The IQ test for seniors: what a normed score after 60 can and cannot tell you

0 The short answer

You can take a normed IQ test at 60, 70 or 80, but the useful one is an adult test whose norms reach age 90, read index by index, and it is never a memory check or a dementia screen. The examiner-given WAIS-5 lists an age range to 90 years and 11 months, and ACIS reports adult norms for ages 16 to 90, but we found no online test with published proof that it works specifically for people over 60, so the confidence interval and the profile matter more than the headline number. If memory or thinking is worrying you or someone close to you, the right step is a physician, not an IQ score.

1 Is There an IQ Test Made Specifically for Seniors?

No single intelligence test is made only for seniors; what exists are adult tests whose norms extend to ages 85 or 90, and the practical question is whether the norms, the format and the setting suit the person. The Wechsler Adult Intelligence Scale, Fifth Edition (WAIS-5) is the clearest example. Pearson's product page, which we read on October 13, 2026, lists the age range as 16:0 to 90:11, a qualification level of C, and a completion time of 45 minutes for the seven subtest Full Scale IQ and 60 minutes for the ten primary index subtests. The page does not explain what level C requires, so anyone who wants a Wechsler test should expect to go through a qualified professional rather than buy it. Our page on the WAIS-5 age range covers that instrument in detail.

The phrase "for seniors" is therefore a statement about norms, not about a special test. A norm is the reference group a score is compared with. An adult test with a 16 to 90 range does not hand a 75 year old a different set of tasks. It compares the 75 year old with a reference group, which in a well built test includes people of a similar age. That is why a person at 72 can score a perfectly ordinary 100: the score says where someone stands among peers, and the average of any age band is 100 by construction. Our page on how IQ scores are normed explains the mechanism, and the page on average IQ by age shows why the average does not fall with age on a normed scale.

What does not exist, as far as we could establish, is an online test advertised with its own published validation for people over 60. A search for the query on October 13, 2026 returned pages that describe tests for seniors but no instrument whose publisher documents a study of that group. RIOT IQ is a useful illustration of the disclosure practice to look for: its page on adult tests says its test is "normed exclusively on adults 18 and older." That is a plain statement of scope, and it also shows that "adults" on many online tests means 18 and up, not older age bands specifically. We read that page on October 13, 2026 and quote only that phrase.

This matters because of how the Standards for Educational and Psychological Testing treat norms. Standard 5.8 says that norms, if used, should refer to clearly described populations, and that those populations should include the people with whom test users will ordinarily wish to compare their examinees. A reader over 60 is entitled to ask whether the reference population of an online test contains people like them, and how many. We come back to what ACIS documents about its own age range in the final section, and we keep the claim narrow there.

There is also a framing problem worth naming. Many pages about intelligence and age compare the average score of 30 year olds with that of 80 year olds and conclude that older people are less intelligent. That comparison mixes ability, cohort, education and health, and the fuller account is on the page about how IQ changes with age. Anyone choosing a test needs the narrower question: which abilities does this test measure, how, and against whom is my score compared.

2 Is an IQ Test a Memory Test or a Dementia Screen?

An IQ test is neither a memory test nor a dementia screen, and a normal or high score does not rule out a medical problem just as a low score does not establish one. The two kinds of assessment answer different questions. An IQ test describes a person's current standing on several cognitive abilities relative to a reference group. A dementia evaluation asks whether a person has a condition, which needs history, examination, often informant reports, and a clinician's judgment about daily functioning.

The Alzheimer's Association's page on medical tests for diagnosis, which we read on October 13, 2026, describes cognitive, functional and behavioral tests that "evaluate memory, thinking and simple problem-solving abilities," notes that some are brief and others longer and more complex, and says more thorough testing is "often given by a neuropsychologist." It also says diagnosis belongs "within the context of an ongoing relationship with a responsible and qualified health care professional." Nothing in that framing is something a self-administered online test can supply.

Even brief clinical screens are contested as population tools. The U.S. Preventive Services Task Force reviewed screening for cognitive impairment in community dwelling adults aged 65 and older without recognized signs or symptoms and concluded that the evidence is insufficient to assess the balance of benefits and harms, an "I statement." That is published in JAMA in 2020. The statement concerns routine screening of people without symptoms, and it does not say that evaluation is unnecessary when there are concerns. It does mean that nobody should treat a home test as a safe all clear.

Medicare, for U.S. readers, describes two routes on its page about cognitive assessment and care plan services, read on October 13, 2026. A provider may "give you a cognitive assessment to look for signs of dementia when you go for other visits," and Part B covers a separate visit "to fully review your cognitive function," for which, after the Part B deductible, you pay 20 percent of the Medicare approved amount. Coverage rules change, so check the current page. The point for this article is that the pathway for a memory concern is clinical and, in the United States, often covered, whereas an online IQ test is not.

The American Psychological Association publishes guidelines for exactly this clinical task. The APA guidelines for the evaluation of dementia and age-related cognitive change (2021) are written for psychologists who carry out such evaluations, and they replace earlier guidance. We cite them to show where the professional standard sits, not to describe their detailed contents, which we did not open in full.

If you are reading this page because you or a relative notices lapses, repeated confusion, trouble with familiar tasks or changes in behavior, stop here and contact a physician. An IQ result can be reassuring or alarming without meaning anything of the kind. A high vocabulary score can sit beside real difficulty with new learning, and a low speed score can be ordinary for a person's age. That is why the later sections stress reading by ability rather than treating a score as a verdict. For people who only want to know where they stand, and who have no concern, the rest of this page is a practical guide.

3 Which Kinds of Assessment Exist for a Senior, and What Does Each Cost?

There are five realistic routes: a physician's cognitive assessment, a psychologist or neuropsychologist, a proctored high IQ society test, a normed online test, and free quizzes, and they differ in purpose far more than in price. The table compares them using prices and facts from pages we opened on October 13, 2026. Where a page did not state a price, the cell says so instead of guessing.

Two details in the table deserve a sentence each. American Mensa's testing page said it offers sessions proctored by Local Group volunteers and private sessions at more than 400 approved facilities, with a "tested at, or above, 98 percent of the general population" requirement, and it showed promotional prices alongside the 60 and 99 dollar figures with end dates in October. We list the standard prices and recommend checking the page, because promotions end. The same page requires a photo ID with proof of date of birth. Our page on the Mensa Norway test covers another national branch.

The second detail is the cost of clinical evaluation. We did not find a published price for a neuropsychological evaluation in an official source, and prices depend on insurance, the clinic and the question being asked, so we do not give a number. That absence is itself informative: a clinical evaluation is a medical service whose price follows from the referral, not a product with a list price.

Where does each route fit a person over 60? If the motive is a medical concern, the first two rows are the only ones that apply. If the motive is a society membership, row four is the route, and our page on accurate IQ tests explains why an unsupervised online score cannot substitute for it. If the motive is curiosity about one's own profile, the normed online test is a reasonable option, provided the report is read with its limits in mind, and the page on professional versus online IQ tests sets out what changes between a supervised and an unsupervised administration. If the motive is simply to play with puzzles, free quizzes serve, and the page on free versus validated tests explains what a free number does not carry.

4 Which Abilities Change With Age, and Which Hold Up?

Vocabulary and general knowledge hold up or rise well into later adulthood, while the speed of simple processing and several measures of current reasoning and memory fall earlier, and the pattern differs by ability rather than by person. The best single source for the shape of this pattern is the study by Hartshorne and Germine, published in Psychological Science in 2015. It combined normative data from the WAIS-III (2,450 healthy, cognitively unimpaired Americans) and the Wechsler Memory Scale with web based data from the TestMyBrain site, and it reported that abilities peak at very different ages. In the authors' words, some abilities peak and begin to decline around high school graduation, some plateau in early adulthood and decline in a person's 30s, and others do not peak until the 40s or later.

The specifics matter for a reader choosing a test. In the paper's normative data, digit symbol coding, a speeded symbol matching task, peaked in the late teens, and digit span peaked in the early twenties. The tasks that draw on learned knowledge (vocabulary, information, comprehension, arithmetic and similarities) peaked significantly later than nearly every other task. Vocabulary peaked around age 50 in the WAIS-III normative data and around 65 in the web sample, and the authors link the later web peak to vocabulary learning continuing later into adulthood. We therefore avoid the common shortcut that vocabulary peaks "in the 60s or 70s": the paper reports roughly 50 in one dataset and roughly 65 in another.

There is a limit to what that paper can say about the 70s and 80s. Its main web experiments covered participants up to about 70 years old, with one replication reaching 73, so the strongest evidence in it concerns the decades before the senior years. A page about people over 60 should say that plainly and not borrow certainty from younger data. The page on how IQ changes with age covers the longitudinal evidence and the Seattle Longitudinal Study in depth, and we do not repeat it here.

Salthouse's selective review in the Journal of the International Neuropsychological Society gives the second half of the picture. He describes a nearly linear decline from early adulthood on measures representing the efficiency or effectiveness of processing, and stability or increase on measures representing "products of processing carried out in the past, such as vocabulary." He also reports that the magnitude of individual differences in performance across the age range he reviewed was nearly constant, and he notes that longitudinal data are needed to learn whether some individuals decline while others stay stable. Two cautions come with his review. First, longitudinal and cross-sectional comparisons sometimes disagree, and one proposed factor is practice from prior test experience, with no consensus yet on the explanation. Second, many studies likely excluded many older adults with poor cognitive performance attributable to health problems or diagnosed pathologies, so averages can flatter older adults.

A third piece of context is the gap between laboratory scores and daily life. Salthouse's review in the Annual Review of Psychology states that adult age differences in many cognitive abilities are well documented and related to success in the workplace and everyday life, yet "increased age is seldom associated with lower levels of real-world functioning," and the reasons for this lab-life discrepancy are not well understood. A lower speed score at 75 does not therefore map onto an inability to manage a household or a career. It tells you about one narrow kind of performance under the clock.

The last row is deliberate. The sources we opened do not give an age curve for the particular reasoning tasks ACIS uses, and we do not infer one. Our page on fluid and crystallized intelligence and the guide to the CHC model explain the families these results come from.

5 Why Does a Profile Matter More Than One Number After 60?

After 60, a single Full Scale IQ can hide a gap of a full standard deviation or more between abilities that age differently, so the six index scores are the more informative part of the report. The idea is simple. If knowledge based abilities hold up and speed based ones drift, a person with an ordinary overall score may have a high verbal index and a lower processing speed index, and those two facts mean different things. A report that gives only the average removes the information that most distinguishes a healthy older adult from a misleading headline.

ACIS reports six indices: VCI (verbal comprehension, Gc), FRI (fluid reasoning, Gf), QRI (quantitative reasoning, Gq), VSI (visual spatial, Gv), WMI (working memory, Gwm) and PSI (processing speed, Gs). Verbal comprehension covers Antonyms, Vocabulary, Information, Synonyms and Similarities. Fluid reasoning covers Matrix Reasoning, Figure Weights, Visual Number Series, Logic Grid and Complex Relations. Quantitative reasoning covers Mathematical Achievement and Arithmetic. Visual spatial covers Visual Puzzles, Layer Rotation and Spatial Comprehension. Working memory covers Digit Span, Alphanumeric Sequencing and Visual Sequence. Processing speed covers Symbol Search and Coding. Our pages on what IQ measures and the cognitive domains explain the terms.

A worked example shows why the spread matters. Imagine, hypothetically, a 74 year old whose VCI is 112 and whose PSI is 88. The difference is 24 points, and with a standard deviation of 15 that is 1.6 standard deviations, which is our arithmetic and not a published figure. In one person's profile, a gap of that size between a knowledge index and a speed index is the kind of pattern the age and cognition literature above would lead one to expect, and by itself it says nothing alarming about thinking ability as a whole. If instead the same person had noticed real change in daily life, that would be a reason to speak to a physician, whatever the numbers.

Reading by index also guards against the opposite error. A person may take a test hoping to prove that nothing has changed and find a high Full Scale IQ. That number can come from strong verbal and quantitative indices while working memory or speed sits lower, and the single figure averages those differences away. Our page on what IQ scores mean and the one on IQ scores versus percentiles explain how to move between the scales, and the percentile calculator converts any index into a rank.

For a senior, the practical consequence is a choice of form. Only a battery that includes the speed, working memory and verbal tasks will show them as separate indices. A shorter form can still be informative about the domains it covers, but it will not show the domains it leaves out. The section on choosing a form below ties each form to what it reports.

6 What Does an Age Norm Do for a 75 Year Old, and What Does It Hide?

An age norm tells you where a score sits relative to people of a comparable age, which removes ordinary slowing from the comparison but cannot tell you why a score is where it is, and the quality of the comparison depends on how many people of that age are in the reference group. On a normed scale, the mean is 100 and the standard deviation is 15 (see the page on why a standard deviation of 15 matters). Scaled subtest scores run from 1 to 19 with a mean of 10 and a standard deviation of 3. If norms are age banded, a 75 year old's raw performance is converted by comparison with the reference group for that band, so slowing that is typical at 75 is already in the reference.

That is a feature and a limit. It is a feature because it prevents the unfair comparison of a 75 year old with a 25 year old. It is a limit because the score then says nothing about change within the person. An unchanged score from 65 to 75 means the person has kept pace with peers, which can happen alongside real raw decline, and a falling score means the person is declining faster than peers. Neither statement is a diagnosis. The page on average IQ by age contrasts raw ability with standardized scores in more depth.

The Standards for Educational and Psychological Testing set the question to ask. Standard 5.9 asks that reports of norming studies specify the population sampled, sampling procedures and participation rates, any weighting, the dates of testing and descriptive statistics, and that technical documentation indicate the precision of the norms themselves. In the chapter on test users, the Standards add that when a test developed and normed for one group is applied to other groups, score interpretations "should be qualified and presented as hypotheses rather than conclusions." We read both passages in the 2014 edition on October 13, 2026. For a reader in their 70s or 80s the second sentence is the useful one: treat any online score as a hypothesis to check against other information.

What does ACIS state? Its technical manual describes the supported adult range as 16 to 90 and documents age bands for score context. We do not repeat figures from it here; open the technical manual and read the age band table yourself. At any age, the 95 percent confidence interval in your report is a range to take seriously rather than a decoration.

Selection also operates in who takes an online test. Someone who is comfortable enough with a computer to take a timed, self administered battery at 80 is probably healthier and more educated than the average 80 year old, which is our inference and not a finding. That cuts two ways: the score compares you with other people who chose to take it, and a reference group made up of such people can be tougher than the general population of the same age. The cure is not to avoid the test, but to read the percentile as "compared with the people in this reference group" and to use the profile and interval to judge.

7 How Do Timed Subtests Work for Older Test Takers?

Timed subtests measure how fast and accurately a person works under a clock, which is where age differences are largest, so the clock is a feature of the test that older test takers should understand before starting, not a verdict on their intelligence. The ACIS home page explains that for the processing speed subtests, Coding and Symbol Search, time limits are essential because they directly measure how quickly a person processes information, and that for other timed subtests, limits prevent excessive rumination so that scores reflect spontaneous problem solving. Our page on why IQ tests are timed covers the logic, and the page on processing speed covers why this is the domain that declines first.

The public pages for the subtests describe the formats. We read them on October 13, 2026. Coding gives 120 seconds to match as many symbols as possible, using on-screen buttons to select the matching number. Symbol Search has 80 puzzles with a 2 minute time limit and a penalty for wrong answers, so accuracy matters as well as speed. Mathematical Achievement has 25 questions with a total time limit of 35 minutes, and a formula table is available. These are descriptions of format, not items.

Those facts bear on preparation. A person who is slower with a mouse or a screen will lose raw points that reflect interface speed rather than ability. The ACIS home page says a physical keyboard can help for tasks like Coding. For a senior this is sensible advice, because a task built from matching and tapping measures hand and screen speed as well as cognitive speed, and the best device is the one the person already uses well. The page on the processing speed test shows what a speed index covers.

The second issue is how the person feels about being timed. Lamont, Swift and Abrams reviewed age based stereotype threat in Psychology and Aging, pooling 82 effect sizes from 3,882 older people with a mean age of 69.5. They found a significant small to medium effect (d = 0.28), larger when stereotype based rather than fact based manipulations were used (d = 0.52) and when performance was tested with cognitive measures (d = 0.36). Many of the studies pooled manipulate exposure to negative age stereotypes, and the average effect is modest. Applied to the reader, the lesson is practical and narrow: do not approach a timed battery as a test of whether you are "still sharp." Treat it as a measurement of how you perform on tasks of this kind, today, in a particular setting.

Third, breaks. ACIS says breaks are allowed and that a test can be completed within 30 days. A long form is not a one sitting commitment. Fatigue, sleep deprivation, stress, distractions, illness and medication can all lower scores, as the ACIS home page notes, so a senior can spread the sessions out. The page on how long an IQ test takes compares durations across instruments, and the timing of each ACIS form is in the section on choosing a form.

8 Will Hearing, Vision and the Device Get in the Way of the Score?

Yes, they can, because a sensory or interface difficulty lowers a score for reasons that have nothing to do with the ability being measured, so checking hearing, glasses and the device before starting protects the result. The numbers on hearing are large. The National Institute on Deafness and Other Communication Disorders says on its page about age related hearing loss, which we read on October 13, 2026, that "about one in three people in the U.S. between the ages of 65 and 74 has hearing loss" and that "nearly half of those older than 75 have difficulty hearing." The page suggests considering a hearing check if screening questions suggest a problem.

Three ACIS subtests are delivered by sound. The public pages for Digit Span and Alphanumeric Sequencing say that numbers, or numbers and letters, play at one per second, and the Digit Span page recommends headphones or a quiet space. The page for Arithmetic tells test takers to wait until the audio finishes before they respond. The ACIS home page says headphones are recommended for audio based subtests such as Digit Span. If hearing is a concern, wear the hearing aids you normally use, use headphones that are comfortable at a good volume, and test the sound before beginning. A hearing difficulty on a task delivered by sound is a measurement problem rather than a cognitive one, which is our inference, and it is the reason to fix the listening conditions first.

Vision works the same way. Several subtests are visual and some are timed, and a screen that is too small, too dim or too far away costs raw points. The ACIS home page recommends a larger screen, a stable internet connection and a quiet environment for visual and timed subtests, and it says the platform works on desktop computers, laptops, tablets and modern smartphones. For a person over 60, the practical reading is to use the largest screen available, glasses as usual and good light, and to avoid a small phone for the visual and speeded tasks.

How many seniors have the equipment? The Pew Research Center's short read on older adults and technology, which we read on October 13, 2026, reports that among U.S. adults 65 and older, 75 percent use the internet, 61 percent own a smartphone, 44 percent own a tablet and 64 percent have home broadband, from a survey fielded from January 25 to February 8, 2021. The figures are from 2021 and ownership has likely changed since, so treat them as an order of magnitude, not a current rate. They do support one conclusion: many older adults have the means, and the real question is comfort with the interface.

There is also a research caution about online testing in this age group. Gates and Kochan reviewed computerized and on-line neuropsychological testing for late life cognition in Current Opinion in Psychiatry and concluded that the psychometric quality, standardization, normative data and administration advice of computerized neurocognitive devices are lacking, so that the risk of diagnostic errors is potentially high. Their subject is computerized tools used to detect neurocognitive disorders, which is a clinical purpose, not an IQ profile. It is still a sound reason to refuse to use any unsupervised online test to look for disease.

9 How Should You Prepare, and Should You Retake the Test Later?

Prepare the conditions, not the content: a good device, a quiet room, working hearing and vision aids, a rested day and a plan for breaks, and do not retake the test soon to look for change. The subtest pages for the audio and quantitative tasks state that no external aids such as calculators, notes, scratch paper or drawing tools are allowed, except where a page says otherwise (the Mathematical Achievement page allows pen and scratch paper but no calculators). Follow the instructions on each subtest page. This page does not describe test content, and nothing here should be read as a way to rehearse items.

A short checklist follows from what the sources above establish. Pick a time of day when you are usually rested and clear headed, because fatigue, sleep deprivation, stress, distractions, illness and medication can all lower performance, as the ACIS home page notes. Use the device you know best. Check the sound before the audio subtests. Plan sessions you can finish without rushing, and use the permitted breaks. If you take regular medication that affects alertness, choose a time when it is steady. If you are unwell, postpone. If a relative helps, the help should be with the device and the setup, not with answers, because the result is only meaningful if the answers are yours.

The most common mistake after a first test is to retake it soon to see whether the score changes. Practice effects are well documented. Calamia, Markon and Tranel carried out meta-analyses of practice effects in neuropsychological assessment covering nearly 1,600 individual effect sizes and reported that practice effects, defined as score increases due to memory for specific items, learned strategies or test sophistication, complicate the interpretation of change, with the use of alternate forms, participant age and the length of the interval associated with the size of the change in many cases. A second administration of the same test within weeks therefore measures partly the first one. Salthouse's selective review also lists practice from prior test experience as one proposed reason cross-sectional and longitudinal comparisons disagree.

If the goal is to track change over years, the advice is the same as for any repeated measurement: keep conditions and form as similar as possible, leave a long interval, and treat a small difference as inside the confidence interval of the first score. If the goal is to learn something about memory problems, an IQ test is the wrong instrument, as the second section explains. The page on IQ and memory shows how closely the two are connected and where they separate, and the page on working memory tests describes what that domain covers.

10 How Do You Read the Report: Interval, Percentile and Index Gaps?

Read the 95 percent confidence interval first, the six indices second, and the single Full Scale number last, because the interval tells you how much the number could move and the indices tell you what it is made of. A score is an estimate with error around it. The Standards for Educational and Psychological Testing note that the standard error of measurement can be used to generate confidence intervals around reported scores, and the ACIS report gives a 95 percent confidence interval, a percentile and scaled subtest scores from 1 to 19. A reader who sees a Full Scale IQ of 108 with a wide interval should hold the number loosely, in the way the page on reliability and validity explains.

Percentiles translate the score. A percentile says what share of the reference group scored lower, and the IQ rarity calculator shows how common any score is. Percentiles are not evenly spaced, so a move of five points near the middle changes the percentile more than a move of five points in the tails, which is why the page on IQ scores versus percentiles warns against averaging them.

Index gaps come next. A person over 60 whose verbal index is a standard deviation above the speed index has a pattern consistent with the abilities we described, and that pattern is common enough in the age literature that it is not by itself a cause for concern. The reading changes when a person has noticed changes in everyday functioning, when scores are low across several indices, or when a relative has observed changes. Then the sensible step is a conversation with a physician, and the IQ report can be brought along as one more piece of information, clearly labeled as an online, unsupervised result.

Three misreadings are worth naming. First, treating a low index as "brain age." No such quantity exists in a normed IQ report. Second, comparing the report with a clinical screening score as if both measured the same thing. They do not. Third, assuming a high Full Scale IQ rules out a problem. It does not, because the test never asked the clinical question. Our page on what IQ scores mean gives the descriptive bands, and the IQ percentile calculator converts between the scales.

11 Which ACIS Form Should a Senior Choose?

Choose the Full Scale form if you want all six indices, because a shorter form shows only the domains it covers, and use the one time prices, the breaks and the free trial to keep the commitment small. The forms and prices below were read on the ACIS home page on October 13, 2026, and prices can change.

All three allow breaks, give 30 days to finish, and include the 5 day quality guarantee. There is no subscription, and there is a free trial with no card. The page on the best online IQ tests compares ACIS with other products, and the page on online IQ tests explains what the product covers.

Which form for which reader? A person who wants to see verbal comprehension, working memory and processing speed as separate indices needs the form that includes all three, and the Full Scale form is the only one that reports all six domains. A person who only wants a rough sense of where they stand may prefer the cheaper form, knowing that a smaller number of subtests means less detail. Time matters too: 175 minutes over 30 days is manageable in sessions of 30 to 45 minutes, and the breaks rule exists for that reason.

Before paying, use the free trial and read the subtest pages for the tasks that look hardest, especially the timed ones. Check what the trial contains when you start, because memory based and speeded tasks can feel demanding when they come without the surrounding profile. If you find the experience uncomfortable, stop. Nothing about the test is meant to be a challenge to endure.

Not everyone should use this page's product. ACIS is in English only, so a person whose first language is not English should read the page on IQ tests for non-native English speakers first. Someone who needs a score for hiring, a school accommodation or admission to a high IQ society needs a different route, as the final section says. A person who needs a psychological or neuropsychological opinion needs a clinician.

12 Where ACIS Sits, and What a Buyer Should Do

ACIS is an online, unsupervised, normed profile with adult norms from 16 to 90, a confidence interval and six indices, but it is not a clinical or diagnostic instrument, it is in English only, and this page does not claim it has been validated specifically for people over 60. The strengths are concrete. The report gives a Full Scale IQ and six primary indices on the standard scale (mean 100, standard deviation 15), scaled subtest scores from 1 to 19, percentiles and a 95 percent confidence interval. Payment is one time, breaks are allowed, a free trial needs no card, and there is a 5 day quality guarantee. The technical manual is where the documentation of norms and scoring lives, and a prospective buyer over 60 should read its age band material before paying.

The limits are as plain. The test is taken on a screen with no examiner, so no one checks hearing, vision, effort or whether someone else is helping. It is not a clinical or diagnostic instrument, so it cannot tell you whether you have a cognitive condition. It is not for hiring, school accommodations or admission to high IQ societies. It is in English only. And on age, the supported range is 16 to 90, the age band documentation is in the technical manual, and a buyer in their 80s should read the interval, not only the single number.

The testing standards support exactly this stance. The Standards for Educational and Psychological Testing (AERA, APA and NCME, 2014) place the burden on test developers to describe norms clearly (Standard 5.8), to document the sampled population, sampling procedures and participation rates and the precision of the norms (Standard 5.9), and to provide interpretations in simple language that describe what the test covers, what scores represent, the precision of the scores and how they are intended to be used (Standard 6.10). They also say that when a test normed for one group is applied to others, interpretations should be presented as hypotheses, not conclusions. The APA publishes separate guidelines for the evaluation of dementia and age-related cognitive change (2021), written for psychologists who carry out clinical evaluations, and nothing in an online IQ report replaces that process. Read the report as a hypothesis about your cognitive profile.

What should a buyer do? First, decide the purpose. If you have a concern about memory or thinking, see a physician, and in the United States ask about Medicare's cognitive assessment visit. Second, if the purpose is curiosity or a baseline profile, start the free trial, read the pages for the timed and audio subtests, set up the device, hearing and room, and choose the form that includes the domains you care about. Third, read the confidence interval before the number and the indices before the Full Scale IQ, and treat any single gap as a feature of the profile rather than a verdict. Fourth, if you want a society membership or a formal evaluation, use the proctored routes in the table above. Fifth, if you want to track change over years, wait a long interval and keep conditions the same. The general guide to IQ tests for adults and the page on IQ tests for former gifted kids cover adjacent readers.
