Which Mensa Denmark IQ test is real, and what a score means
Mensa Denmark offers two very different things under one name: a free online test that its own pages call indicative, and a paid test with 45 tasks in 20 minutes that is the route to membership. This page separates them, explains how the widely shared iqtest.dk fits in, shows what each score can and cannot tell you, and says what an adult can do before paying a fee.
Mensa Denmark's membership and FAQ pages give its admission test as 45 tasks in 20 minutes, at 250 kroner.
0 The short answer
Mensa Denmark has two tests that share a name but not a purpose: a free online "for fun" test on mensa.dk that its pages say does not count for admission, and a supervised test booked through its event list, which its pages describe as 45 tasks in 20 minutes at 250 kroner, scored by an external psychologist. The widely shared iqtest.dk is not the admission test: mensa.dk says its online test is based on iqtest.dk, credits it to Anders Ditlev Jensen, MD, and says nothing that makes iqtest.dk a Mensa product, while the iqtest.dk home page we opened shows no test at all. A normed online battery is a different instrument and not a Mensa Denmark test: ACIS Quick costs 25 dollars one time and takes about 45 minutes (prices read November 4, 2026, and subject to change). The decisive limit is that no online score, ACIS included, is accepted by Mensa Denmark or predicts a pass.

The Mensa Denmark online IQ test is a free, anonymous test at mensa.dk that the site itself labels "for sjov" (for fun), and Mensa Denmark states that it does not grant admission. We opened the test page, the page that introduces it and the home page on November 4, 2026, and translated the Danish ourselves. The introduction page says the test is not admission giving (in Danish, "ikke adgangsgivende"), that no registration is needed, that it is anonymous and that no result is saved, and it encourages people who score high to take the admission test. The test page itself repeats the point in its disclaimers: the result is indicative only and assumes it is the first time you take the test, and admission to Mensa requires placing in the top 2 percent on an official IQ test. It also says the correct answers are not published and that it is not permitted to publish the solutions online.
That last rule matters to anyone searching for a practice version. The disclaimer is the site's own, and it describes the purpose of the test: a quick, uncontrolled indication. Mensa Denmark's FAQ page says the same in plain terms. It calls the online test only a for fun test, says Mensa accepts only results obtained in a controlled and approved IQ test, and says the online result cannot be used for membership. Three separate pages of one organization agree on this, which is rare enough on a topic full of rumor to be worth stating first.
The test page does not describe itself as a miniature of the admission test. It presents image based items that you answer one at a time, with arrows to move between them and a button to end the test. The page also states that the online result is an IQ calculated with a standard deviation of 15. We do not reproduce or describe any item, and we did not open the items beyond what the page shows about its own structure, because the site asks that solutions stay unpublished and because the Standards discussed later treat item exposure as a threat to score meaning.
The home page of mensa.dk frames the offer the same way. It describes Mensa as an association for the top 2 percent, invites visitors to test their intelligence with the online for fun test, and separately invites them to book a place and test their IQ officially. It also states that the association has more than 2,000 members in Denmark and more than 150,000 worldwide. Mensa International also lists an online challenge on its own site, which the page on the international Mensa IQ Challenge covers. The practical reading is simple: the free test is an entry point to the conversation, the booked test is the entry point to membership, and the two should never be mixed in a sentence such as "I got 135 on the Mensa Denmark test" unless you say which one.
2 Is iqtest.dk the Same Test as Mensa Denmark's?
The sources we opened do not establish that iqtest.dk is a Mensa Denmark test: mensa.dk says its online test is based on iqtest.dk and names Anders Ditlev Jensen, MD, as its developer, while one academic paper calls the same test the IQTest of the Mensa Denmark group. That is the disagreement behind the search "iqtest dk", and the honest answer is to lay the evidence side by side.
The first piece of evidence is on the Mensa Denmark test page. Its credits say, in our translation, that the "for fun" test on mensa.dk is based on IQtest.dk developed by Anders Ditlev Jensen, MD, and that the HTML version was developed by others credited by name. The wording describes a relationship in one direction: mensa.dk built on iqtest.dk. It does not say that Mensa Denmark owns iqtest.dk, that Mensa Denmark commissioned it, or that the two tests are identical today. The introduction page, which we also opened, does not mention iqtest.dk at all.
The second piece is an academic one. Cerda Etchepare, Pérez Wilson, Melipillán Araneda and Ortega-Ruiz (2015), in Universitas Psychologica, present what their abstract calls an adaptation of the IQTest of the Mensa Denmark group (www.iqtest.dk) for use in Chile. That is the strongest source we found that ties the two names together, but it is a Chilean research paper using a label, and it cannot override what Mensa Denmark says about itself. The two statements fit together if the paper used a common shorthand for a web test that mensa.dk later reused, and they conflict if the paper meant that Mensa Denmark ran the site. The paper's abstract does not settle which. We read the abstract and the bibliographic record, not the full text, so we report only what the abstract says.
The third piece is the site itself. On November 4, 2026 the iqtest.dk home page we opened shows a short Danish introduction that says the site offers a way to test intelligence through a culture neutral methodology, signed only by "admin", dated October 2, 2026, with a login form. We found no test, no item count, no time limit, no score scale, no norms, no named author and no mention of Mensa on it. A site can serve different content to different visitors, so we say only what we saw. A 2012 news article in the Danish engineering weekly Ingeniøren (Mensa søger 11.000 mulige medlemmer) is a smaller clue: a reader comment under it says the same test exists in black and white at iqtest.dk if you choose English. That is an unverified reader remark from 2012, and we use it only to show how old the association between the two is.
What a reader can safely conclude is limited:
Mensa Denmark's own page credits iqtest.dk as the basis of its free test, so the two are related.
No page we opened says that iqtest.dk is operated by Mensa Denmark or that a score there counts for admission.
The page you take today on mensa.dk is the version Mensa Denmark stands behind, and it says it is indicative only.
Any claim that a number from iqtest.dk is "the Mensa score" goes beyond the sources.
Several test hosting sites and forums say more about iqtest.dk, including a year of origin, a question count and a time limit. We treat those as leads, not facts, because none of them is an official page of the author or of Mensa Denmark. If the author's own page or a Mensa Denmark statement appears, this section should be updated.
3 How Many Questions, What Time Limit and What Score Scale?
The online test page does not state a number of questions or a time limit, while Mensa Denmark's membership and FAQ pages give the admission test as 45 tasks with 20 minutes available, and both use a scale with a mean of 100 and a standard deviation of 15. Those are three different facts, and mixing them is the most common error in what is written about this test.
For the online test, the results screen we opened says "Du har besvaret opgaver" (you have answered tasks) and leaves the number blank, and no page we opened gives a count or a clock. Anyone quoting "x questions in y minutes" for the online test is quoting a third party. The scale is stated: the page says the online IQ is calculated with a standard deviation of 15, and it explains that an IQ between 85 and 115 falls in what is called the normal range. A standard deviation of 15 means the same thing here as on most professional tests, and the page on why the standard deviation is 15 explains the convention.
For the admission test, the membership page says the test, which it calls FRT, has 45 tasks and that you have 20 minutes. The FAQ page says it in the same words: FRT consists of 45 tasks and you have 20 minutes available. The FAQ page adds that you only need to be able to see the figures and write your answers on an answer sheet, which describes a paper test taken in person. Twenty minutes for 45 tasks works out to about 27 seconds per task on average, which is our arithmetic and not a figure from Mensa. The speed demand is part of what the test measures.
One page disagrees on detail. The event list, which we opened the same day, says that FRT is used for young people aged 14 to 18 and says nothing about the format for adults beyond the statement that no prior knowledge is needed. The membership page, by contrast, names FRT with the 45 tasks and 20 minutes without an age qualifier. We report the membership and FAQ pages as the fuller description and note that the event list is silent on the adult test name. This page is written for adults, and the age rules are limited to one sentence: Mensa Denmark sets 14 as the minimum age for its test, and its terms add conditions for people under 18.
The top 2 percent line needs one more sentence. The FAQ page says the entry requirement is that the result corresponds to an IQ within the top 2 percent of the population, and it equates that with an IQ over 130 on the scale Mensa Denmark uses. On a normal curve with a mean of 100 and a standard deviation of 15, the 98th percentile lies at about 130.8, which is our arithmetic. So 130 is a rounded statement of the line, and a score of exactly 130 sits at about the 97.7th percentile. The pages on how rare a given IQ is and on how IQ scores differ from percentiles let you move between the two scales yourself.
4 Does the Online Test Count for Mensa Denmark Membership?
The online test does not count for membership: Mensa Denmark accepts results only from a controlled and approved IQ test, and its route runs through a booked test, a result letter and a certificate, or through a prior psychologist's report that Mensa Denmark assesses. The rest of this section sets out that route as the pages describe it on November 4, 2026. Rules and fees can change, and Mensa Denmark's pages are the authority.
The admission test is booked from the event list. The membership page and the event list give the price as 250 kroner for the test. The membership page lists an assessment of an external test at 100 kroner and an annual membership fee of 550 kroner, which includes the member magazine. Registration is binding. The terms page says the test fee is not refunded for cancellation, no show or late arrival, that it is not possible to cancel or change the test date, and that you must bring a valid passport or Danish driving licence. The membership page adds that photo identification is checked at the test.
Who marks the test is stated: the membership page says Mensa Denmark has an external psychologist responsible for scoring all tests taken with it, and that the result letter and certificate arrive within three to four weeks. Attempts are limited. The membership page says the test can be taken three times in all, with at least six months between attempts, and the terms page lists the matching conditions: no more than two earlier participations in FRT and none within the six months before the test date. The event list shows seat counts between 3 and 20 per event, which means these are small group sessions.
There is a second route that skips the booked test. The membership page says Mensa Denmark accepts results from tests taken elsewhere, and it names the WAIS, the WISC, the Stanford-Binet and the Cattell Culture Fair as examples. You provide the name of the test, the detailed result confirmed by a psychologist, the psychologist's contact details, and when the test was taken and how long it took. Checking whether a test is accepted is free; assessing the documentation costs 100 kroner. The wording is a list of examples, not a complete list, and the page says nothing that makes an online test or a battery like ACIS acceptable. A reader who already holds a psychologist's report should ask Mensa Denmark before booking the 250 kroner test, because the answer decides which route is cheaper.
Three conditions follow from this for the reader. The first is that a free online result, however high, has no standing with the association. The second is that the booked route is a one time trip that you attempt at most three times. The third is that the decision to take the official test is better made on the strength of a sensible estimate than on the strength of a single free number, and the page on high IQ society requirements compares what other societies require. The page on the Mensa IQ test and its score line covers the score needed across Mensa, and the sibling page on Mensa qualifying test scores covers which scores count in which country.
5 What Does the Official Mensa Denmark Test Measure?
The official test is a figure based reasoning test, and in Cattell-Horn-Carroll terms a test built only from figures samples fluid reasoning (Gf), the ability to solve problems that cannot be solved from learned facts, so it is a narrow window on one broad ability and not a profile. Mensa Denmark's FAQ page says the association uses the Figure Reasoning Test, FRT, developed by John C. Daniels, and describes it as a test of 45 tasks. The page says you need only see the figures and write answers on a sheet. The event list adds that no prior knowledge is needed. We did not open the test itself and we do not describe any of its tasks. We have no manual for it, so we cannot say how its scores are built or normed, and nothing on the Mensa Denmark pages we opened says.
The CHC model, explained on the page about the CHC model and its abilities, organizes cognitive abilities in layers, with general ability at the top, several broad abilities in the middle and many narrow abilities below. Fluid reasoning (Gf) is one broad ability. Others include crystallized knowledge (Gc), visual processing (Gv), working memory capacity (Gwm), quantitative knowledge (Gq) and processing speed (Gs). A test whose items are all figures and whose answer format is a sheet of choices cannot say anything specific about vocabulary, arithmetic, memory span or speed of simple tasks. It can say something about how well a person finds the rule in a pattern. The page on what IQ measures explains why a single ability can still be a useful estimate of general ability and where that argument stops.
The ACIS page on matrix reasoning describes the matrix format in CHC terms: tasks that measure rule discovery in unfamiliar visual patterns, in which the examinee inspects relationships, infers transformations and selects the option that best completes the structure. It is closely related to Gf, and the page says one subtest should never be read as the whole construct. That description is general to the format. We do not claim that FRT tasks are matrices; Mensa Denmark's pages we opened call them figures. A second ACIS subtest page, figure weights, covers a different fluid reasoning subtest, and the logic grid subtest page covers deductive reasoning under several constraints, a third. The three show how a battery samples fluid reasoning with more than one format, which a single 20 minute test cannot.
Is a figure test fair across languages? The page on culture-fair IQ tests explains the goal and its limits. Figures reduce the load of reading and of school vocabulary, which is why Mensa Denmark can say no prior knowledge is needed. They do not remove familiarity with test taking, with timed work and with abstract patterns, and they do not remove the effect of the clock. A person who works slowly and carefully is at a disadvantage on 45 tasks in 20 minutes, since the format rewards speed along with accuracy.
What a single format cannot tell youA test with one task format measures that format along with whatever the format shares with general ability. Two people with the same score can differ in knowledge, memory and speed, none of which the test samples. The Mensa criterion is a position in the top 2 percent on an approved test, and it is silent on the rest of a person's profile. The page on the cognitive domains in IQ testing lists the domains a fuller battery covers.
6 How Does Mensa Denmark's Test Compare With Mensa Norway's?
Mensa Denmark and Mensa Norway both describe an admission test of 45 tasks and 20 minutes taken in person, but they differ in price, in the age they set and in the free test they publish, and nothing we opened says the two tests are the same instrument. Official Mensa pages from both associations were opened on November 4, 2026. Norwegian prices are in Norwegian kroner and Danish prices in Danish kroner, so the numbers are not comparable without a currency conversion, which we do not make.
Mensa Norway's test page states, in the Norwegian original, that the test consists of 45 tasks and is scheduled for 20 minutes, that Mensa Norway offers an authorized IQ test for everyone over 16, that you must bring valid photo identification, that it costs 550 Norwegian kroner and that it takes place in person in a suitable room, usually a classroom. The same page describes a free online test at test.mensa.no, which, in Mensa Norway's words, is not an authorized test but gives an indication of IQ level. The page does not name the admission test as FRT, so the shared format could be a coincidence of design or a shared test. Mensa Denmark names FRT and its developer; Mensa Norway's page we opened does not.
The comparison on the points that matter to a reader looks like this.

The ACIS page on the Mensa Norway test reviews the free Norwegian test in depth, including its format, its scoring and what its score tells you, and it should be read for that test. The point that carries over is the same on both sides of the border. A free online test from either association is a screen, an official one is an admission route, and a number from the first is not a number from the second. The sibling page on the Mensa Germany test covers a third national route. If you are comparing the two countries because you live near the border or hold two residences, the association you apply to is the association whose rules apply, and each association decides what it accepts. A result from one country may or may not be recognized by the other, and neither page we opened says.
7 Which Real Options Give a Danish Adult an IQ Result, and How Do They Compare?
The real options differ in who supervises the session, who the result is compared with and what the result is accepted for, and a free score is useful only for the first of those purposes: finding out whether the next step is worth the money. The table compares what a Danish adult can actually do. Mensa Denmark facts come from its pages opened on November 4, 2026. Where a page printed no figure, the cell says so, and prices can change. The row for a psychologist rests on the Mensa Denmark route for outside tests, not on a Danish price list, which we did not find on a page we opened.

Three readings follow. First, the only two Mensa Denmark options that can lead to membership are the supervised test and a psychologist's report, and the first costs less in fees that are published. Second, the ACIS forms cost more than the free test and sample more domains than a figure test does, but they are unsupervised and do not count for any society. Third, a job screening practice test is not an IQ test, and a score from one should never be quoted as an IQ. The page on every way to take an IQ test lays out in person and online routes side by side, and the page on the best online IQ tests compares online products against a published standard.
8 What Does a Score on the Danish Online Test Mean?
A score on the Mensa Denmark online test means only what the page says it means: an indication, assuming a first attempt, expressed on a scale with a standard deviation of 15, with no stated reference group and no stated margin of error. The page tells the reader this itself. The result is indicative only, it assumes you have not taken the test before, and when few answers are correct the test says it cannot calculate the IQ reliably. We opened those lines on November 4, 2026 and translated them.
The questions that decide how far to trust any IQ score are the ones the Standards for Educational and Psychological Testing (AERA, APA and NCME, 2014), which we read in their open access edition, lay out. Standard 2.3 says that for each total score, subscore or combination of scores that is to be interpreted, estimates of relevant indices of reliability and precision should be reported. Standard 2.14 adds that where cut scores are specified for selection or classification, standard errors of measurement should be reported in the vicinity of each cut score. Mensa's top 2 percent line is a cut score. The page on reliability and validity in IQ testing explains these ideas, and the page on how IQ scores are normed explains why a score is a position in a reference group and not a free standing number. On the Mensa Denmark online test page, we found no reliability figure, no standard error and no description of the reference group, which does not mean none exists. It means that a reader cannot tell how much a point on that scale matters.
What evidence exists for the iqtest.dk family of tests? The 2015 paper by Cerda Etchepare and colleagues in Universitas Psychologica is the one peer reviewed source we found. Its abstract reports two samples of Chilean secondary school students, 2,994 in a normal group and 394 in an advanced group, and says the authors report adequate reliability indices, confirmed construct validity through factor analysis and Rasch analysis, checked concurrent validity against another standardized intelligence test used in Chilean schools, and found scores correlated positively with mathematics performance. It concludes that the instrument differentiates the two groups. That is a narrow finding. It concerns a Spanish adaptation, a school population and a group discrimination purpose, and it does not tell you how a Danish adult's online score relates to an admission score. We read the abstract, not the full paper, and we make no further claim about its methods. The evidence also does not make the adaptation a Mensa instrument.
Two practical rules follow. First, treat a score from the online test as a band, not a point. Mensa Denmark's FAQ gives a rule of thumb that is more useful than the number itself: it is a good idea to take Mensa's official test if you scored over 120 on the online test. The threshold of 120 sits ten points below the 130 line, which is sensible for an uncontrolled test with no stated error, and it is a rule of thumb from the association, not a statistic. Second, never compare an online number with an official one as if they were on the same footing. The page on what an IQ score means explains the bands, and the page on what makes an IQ test accurate lists the checks to apply to any test.
Reading a single figure test also means keeping in mind how a short test differs from a battery. A short test has fewer observations behind its score, so its error band is wider. The Standards add, in a comment on Standard 2.3, that when the interpretation of scores centers on the peaks and valleys of a score profile, the reliability of score differences is critical. That is why a gap between two short scores is less trustworthy than either score alone. The ACIS page on index score differences explains how to read gaps between indices when a battery gives you several.
9 Can You Practice for the Mensa Denmark Test, and Do Retakes Raise the Score?
Mensa Denmark offers no practice test as such, its own online test is the nearest thing to one, and research on retesting says that a second attempt at a cognitive test usually scores higher, which is consistent with the association capping the official test at three attempts. The association's membership page says the type of tasks resembles what you may meet if you take the indicative test on its "Test din IQ" page, in our translation. That is the closest official statement of a practice relationship. It is also the reason to take the free test once and then stop: the test page says its result assumes you are taking it for the first time.
What does the research say about a second attempt? Hausknecht, Halpert, Di Paolo and Moriarty Gerrard (2007), in the Journal of Applied Psychology, summarized 50 studies of practice effects on cognitive ability tests. Their abstract reports 107 samples and 134,436 participants and an adjusted overall effect size of .26, and it says the effects were larger when practice was accompanied by test coaching and when identical forms were used. The abstract does not say which tests were used in each study, and it does not apply to Mensa Denmark's test specifically. The sound reading is general: when someone sees the same kind of tasks twice, the second score tends to be higher, and part of that gain is familiarity and not ability. The page on retaking an IQ test covers how long to wait and how to compare two scores.
Mensa Denmark's rules fit that picture. The terms page limits earlier participation in FRT to two occasions and requires six months since the last one, and the membership page states a maximum of three attempts with at least half a year between them. The Standards for Educational and Psychological Testing (AERA, APA and NCME, 2014) say in their chapter on test administration, scoring, reporting and interpretation that retest policies should be set by the test developer or user and clearly communicated, and that retesting is intended to decrease the probability that a person will be incorrectly classified as not meeting some standard. A cap and a waiting period are one way to give a second chance without turning the test into a drill.
There is also a point about security. The online test page asks that solutions not be published, and the Standards say that unauthorized distribution of items to some examinees but not others could give some test takers an advantage and that results should then be interpreted with caution. We therefore do not point to any site that publishes items or answer keys for the Danish test, and we describe no tasks. A person who prepares by memorizing leaked items produces a score that no longer means what the test intends. A person who prepares by getting comfortable with timed pattern tasks in general is doing something the research describes as ordinary practice. The page on the ICAR item pool describes one public domain set of reasoning items and what it can and cannot support.
10 What Conditions Make an Unsupervised Test Worth Taking?
An unsupervised online test is worth taking only when you create the conditions its norms assume, because the Standards say that unproctored administrations where standardization cannot be ensured could give some test takers an advantage, and that results should then be read with caution. The Mensa Denmark online test cannot check any of this, which is another reason it is an indication and not a result.
The Standards are specific. In their chapter on fairness, they say that unproctored test administrations where standardization cannot be ensured could provide an advantage to some test takers over others, and that in those situations test results should be interpreted with caution. In their chapter on psychological testing and assessment, they say that the interpreter of the results should be informed if the test was unproctored. The APA's Guidelines for Psychological Assessment and Evaluation (2020), which we opened as a PDF on November 4, 2026, state in Guideline 8 that standardized administration is most important because the validity of responses may be compromised when adherence to standardization is not met, and that normative data or decision rules may not be accurate when administration procedures do not follow those used in standardizing the test. Both documents say the same thing in different words: a score earns its meaning from the conditions under which it was gathered.
For a reader, that translates into plain steps for any unsupervised session:
Take it once, in one sitting, as a first attempt (see also the sibling page on the Mensa Home Test), since the Mensa Denmark page states that the result assumes a first attempt.
Use a quiet room, a charged device and a screen large enough to see every detail of a figure without zooming.
Do not look anything up, and do not take the test alongside someone else.
Choose a time when you are rested, because fatigue and distraction lower a score without changing ability.
Treat the result as a band, and write down the date and the conditions so that you can judge it later.
The supervised option removes the guesswork, which is part of its value. The terms page says to bring a valid passport or Danish driving licence, the FAQ page says answers go on an answer sheet, and the event list shows small groups. Everything an examiner would otherwise have to assume is controlled. If you are comparing an online result with an official one, remember that the second was taken under conditions the first could not guarantee.
Audio is a separate case on some batteries. Three ACIS subtests, Digit Span, Alphanumeric Sequencing and Arithmetic, present their items as audio and need working sound, so check your speakers or headphones before you begin them. Breaks are allowed between subtests on every ACIS form, progress is saved and you have 30 days to finish. Those provisions help a reader who cannot give three hours to one sitting, but they do not replace a quiet room.
11 What Can an Adult Normed Battery Add Before You Pay a Fee?
An adult normed battery can add a profile and a confidence interval around a Full Scale IQ, which a single figure test cannot give, and it does so by sampling several abilities with several formats and comparing a person with adults of a stated age range, though it cannot be the test Mensa accepts. The point of taking one before paying 250 kroner is information, not permission.
Start with the ability the Danish test samples. ACIS places fluid reasoning in the Fluid Reasoning Index, FRI, which holds five subtests: Matrix Reasoning, Figure Weights, Visual Number Series, Logic Grid and Complex Relations. Quick includes two of them, Matrix Reasoning and Figure Weights, and Optimized adds Logic Grid; the Full Scale form holds all five. The subtest pages describe each format without showing items. An adult who wants to know roughly where fluid reasoning sits, on a scale with a mean of 100 and a standard deviation of 15, with a percentile and a range around it, can see that on a report.
Then look at the rest of the profile, because it explains what a single score hides. A figure test with 45 tasks in 20 minutes depends on speed as well as reasoning. The two ACIS processing speed subtests, Coding and Symbol Search, measure speed on simple visual tasks under time pressure, and the processing speed subtest pages describe what that domain is and how it is read. A reader whose reasoning index is high and whose speed index is lower will understand why a timed paper test may feel harder than the reasoning itself. A gap between two indices should be read with its interval in mind, as the discussion of score gaps above explains.
A report also answers questions the Mensa route does not. The pages on IQ tests for adults and on gifted tests for adults explain what an adult normed result can and cannot support, and the page on free IQ tests covers the free route. If your question is the narrow one, whether to spend 250 kroner on an attempt, the useful output is a range for fluid reasoning and a note on speed. If your question is the broader one, how your abilities compare, a full battery answers it and a figure test does not. In neither case does an ACIS score tell you what you would score on a different test. It is a different instrument with its own norms, and a gap of several points between two instruments is ordinary measurement error and not a verdict on either.
12 Where ACIS Sits, and What a Buyer Should Do
ACIS is an online, unsupervised, adult normed battery that gives a Full Scale IQ and six indices; it is not a Mensa test, it is not accepted by Mensa Denmark or by any high IQ society, and it does not predict a pass. The ACIS research page, read on November 4, 2026, puts the limit in its own words: ACIS "is not intended for clinical diagnosis, hiring decisions, accommodation determinations or admission to high IQ societies" (see ACIS for research). It is also English only, and the technical documentation says verbal and knowledge tasks are affected by English proficiency and educational exposure. The documentation is on the technical manual page.
The Standards for Educational and Psychological Testing (AERA, APA and NCME, 2014) give the frame for reading any of these scores. They ask that users have evidence of reliability and precision for the scores they interpret, that cut scores come with standard errors near the cut, that standardized procedures be followed and that results from unproctored sessions be interpreted with caution. The APA's Guidelines for Psychological Assessment and Evaluation (2020) add that norms must fit the person tested and the procedure used. Applied to this topic, that means three things. A free online number is an indication. An ACIS result is a normed adult picture gathered without supervision. A Mensa Denmark result is a supervised score from an approved test, scored by an external psychologist. Only the last opens the door.
What it costs, as read on November 4, 2026 and subject to change: ACIS Quick is 25 dollars for 6 subtests in 3 domains, about 45 minutes; Optimized is 35 dollars for 13 subtests in 5 domains, about 110 minutes; Full Scale is 59 dollars for all 20 subtests in six domains, about 175 minutes. Every form reports a Full Scale IQ with its 95 percent confidence interval, and the Custom Test lets you pick subtests at 10 dollars each. There is no subscription, and the free trial needs no card. The refund policy reads: "Full refund within 5 days if the report does not deliver the features described at checkout or a technical issue prevents you from accessing your results." The general page on how IQ scores are normed explains what a reference group is, and the technical manual holds the ACIS documentation.
A sensible order for a Danish adult who is curious about Mensa:
Take the free Mensa Denmark online test once, under quiet conditions, and read the result as a band.
If you score over 120, which the association itself uses as its rule of thumb, consider the official test; if not, consider whether you still want to attempt it.
If you want a profile first, start the ACIS free trial with no card, open an example report and choose a form.
If you hold a psychologist's report, ask Mensa Denmark whether the test is accepted before you book anything.
If you book, remember that registration is binding, the fee is not refunded and you can attempt the test three times at most.

14 Frequently Asked Questions
What is the Mensa Denmark IQ test?
Mensa Denmark offers two tests. A free online "for fun" test on mensa.dk is indicative only and does not grant admission. The admission test, which its pages call FRT, has 45 tasks and 20 minutes, costs 250 kroner, is booked through the event list and is scored by an external psychologist.
Is the Mensa Denmark IQ test free?
Only the online test is free, and it does not count for membership. Mensa Denmark's pages say the online result cannot be used for admission. The admission test costs 250 kroner, and having a psychologist's report from another test assessed costs 100 kroner. Prices were read on November 4, 2026.
Can you take the Mensa Denmark IQ test online?
You can take the free online test, but not the admission test. The online test is anonymous, saves no result and is described as indicative. Admission requires a booked, in person test with photo identification, or a psychologist's report from another test that Mensa Denmark assesses and accepts.
What is iqtest.dk?
iqtest.dk is a Danish web address that mensa.dk credits as the basis of its online test, developed by Anders Ditlev Jensen, MD. The home page we opened on November 4, 2026 showed no test, no author beyond an admin name and no norms. Treat older descriptions of the site as unverified.
Is iqtest.dk accurate?
We found no published reliability, norms or error band for it on an official page. A 2015 paper reported adequate reliability and validity for a Spanish adaptation among Chilean secondary school students, which does not describe the Danish original. Mensa Denmark calls its own online result indicative only.
Is there a Mensa Denmark practice test?
Mensa Denmark offers no practice test as such. Its membership page says the tasks resemble those on its free online test, which assumes a first attempt, and publishing solutions online is not permitted. The association allows three attempts at the official test, with at least six months between them.
Is the Mensa Denmark online test the same as the official test?
No. The online test is free, anonymous, unsupervised and indicative, while the official FRT is a paper test taken in person with photo identification and scored by an external psychologist. Mensa Denmark says only that the task types resemble each other, not that the scores are equivalent.
How many questions and how long is the official Mensa Denmark test?
Mensa Denmark's membership and FAQ pages say FRT has 45 tasks and gives you 20 minutes. That works out to about 27 seconds per task, our arithmetic. The online test page states neither a question count nor a time limit, so figures quoted for it come from third parties.
What score do you need to join Mensa Denmark?
The FAQ page sets the requirement as a result within the top 2 percent of the population and equates it with an IQ over 130 on a scale with a mean of 100 and a standard deviation of 15. On a normal curve, the 98th percentile is about 130.8, our arithmetic.
How many times can you take the Mensa Denmark test?
Up to three times in all, with at least six months between attempts, according to the membership page. The terms add that you may have taken FRT at most twice before, and not within the six months before the test date.
Who scores the Mensa Denmark test, and how long do results take?
Mensa Denmark says an external psychologist is responsible for scoring every test taken with it. The membership page says you receive a result letter and certificate within three to four weeks. The pages we opened do not describe how the raw score is converted into an IQ.
Can you join Mensa Denmark with another IQ test?
Possibly. The membership page says Mensa Denmark assesses results from tests taken elsewhere, naming the WAIS, WISC, Stanford-Binet and Cattell Culture Fair as examples, for 100 kroner. You need a psychologist confirmed result and contact details. Checking whether a particular test is accepted is free.
How does the Mensa Denmark test compare with the Mensa Norway test?
Both associations describe an in person admission test of 45 tasks and 20 minutes, and both publish a free online test that is not admission giving. They differ in price, 250 Danish kroner against 550 Norwegian kroner, and in naming: only Mensa Denmark's pages name the test as FRT.
What does the official Mensa Denmark test measure?
Mensa Denmark describes FRT as built from figures and needing no prior knowledge. In Cattell-Horn-Carroll terms, a figure only test samples fluid reasoning, not vocabulary, memory or the speed of simple tasks. We found no manual or technical data for FRT on the pages we opened.
What does a score on the online test mean?
It means an indication on a scale with a standard deviation of 15, assuming a first attempt. The page itself says the test cannot calculate an IQ reliably when few answers are correct. No reference group or margin of error is stated, so read the number as a band.
Should I take the official test if I score high online?
Mensa Denmark's FAQ suggests taking the official test if you scored over 120 online and calls that a rule of thumb. It is not a statistic. Because the online test states no error band, a high number is a reason to consider the official test, not a prediction of the result.
Will retaking a test raise my score?
Usually a little. A meta-analysis of 107 samples and 134,436 participants reported an adjusted overall practice effect of .26, larger with coaching and identical forms. Part of such a gain is familiarity and not ability, which fits Mensa Denmark capping attempts and requiring six months between them.
Can an ACIS score get me into Mensa Denmark?
No. ACIS is not accepted by Mensa Denmark or any high IQ society and does not predict a pass. Its own research page says it is not intended for admission to high IQ societies. It can give an adult normed picture by index before you decide whether to pay a fee.
How can I check where I stand before paying 250 kroner?
Take the free Mensa Denmark online test once and read it as a band. For a fuller picture, an adult normed battery such as ACIS reports a Full Scale IQ with a 95 percent confidence interval. ACIS is online and unsupervised, so it is an estimate and not a result Mensa accepts.
Is a figure test fair if Danish is not my first language?
A figure test reduces reading and vocabulary demands, and Mensa Denmark says no prior knowledge is needed. It does not remove the effect of the clock or of familiarity with test formats. The association's booking pages are in Danish, so confirm the language of your session with Mensa Denmark.
What should I do on the day of a supervised test?
Bring a valid passport or Danish driving licence and arrive on time. Mensa Denmark's terms say the fee is not refunded for cancellation, no show or late arrival, and the date cannot be changed. Rest beforehand, since the test is timed and the booking is binding.

You get a profile, not a number
ACIS measures six CHC domains across 20 subtests and reports each one with its own normed score and confidence interval, so you can see where you are strong and where you are not.
