IQ Test — Frequently Asked Questions

The assessment presents reasoning problems drawn from four domains — verbal, numerical, spatial and abstract or logical reasoning. You work through them in one sitting, and your answers are scored against a standardised distribution rather than counted as a simple total, so the result places you relative to other test takers rather than giving you a mark out of ten.

Nothing is installed and no account is needed to begin. You can start the test straight away, or read How IQ Tests Work for the reasoning behind the item types.

IQ Metrics runs eight test formats on one shared scoring engine. What changes between them is which abilities are sampled, how many items you answer, and how the result is reported.

• Mix IQ Test — 30 questions in about 30 minutes, shuffled across all four domains. The fastest way to start.
• Classical IQ Test — 40–50 items in 20–25 minutes. The only format that samples all four domains in depth and returns a per-domain breakdown alongside the composite.
• Timed IQ Test — 15–18 items under a 10-minute cap, reported as a directional estimate rather than a full profile.
• Culture-Fair IQ Test — abstract and spatial patterns only, with nothing to read and nothing to calculate.
• Kids IQ Test — ages 4–17, age-banded items and age-normed scoring.

There are also three single-domain deep-dives — verbal, spatial and numerical. The full side-by-side comparison, including item counts and timings, is on the IQ Tests Hub.

It depends which format you choose. The Timed IQ Test is capped at 10 minutes, the single-domain tests run 10–12 minutes, Classical and Culture-Fair take 20–25 minutes, and the Mix IQ Test allows 30.

Scoring happens the moment you submit, so there is no waiting for a result. Finish in one sitting if you can — interruptions add noise to a measurement that is already sensitive to fatigue and attention.

No. You can begin any of the formats without creating an account or signing in.

Your name and email address are needed at the end, so that the certificate can be issued in your name and your report can reach you. What is stored, for how long, and how to have it removed is set out in the Security and Privacy Policy.

Yes. Each test format page carries worked sample items with the reasoning spelled out, so you can see what a question of that type actually looks like before committing to a sitting. Those samples are illustrative: they are not scored and they have no effect on your result.

The scored assessment behaves differently — answers are not revealed as you go, and your score, percentile and profile are produced at the end. Browse the samples from the IQ Tests Hub, or go straight to the scored test.

Cramming does not help much either way, because the items test reasoning rather than recall. The IQ Test Guide covers what genuinely makes a difference on the day.

It depends which format you take. The Mix IQ Test is 30 questions. Classical and Culture-Fair run 40–50 items, the three single-domain tests 20–25, and the Timed format 15–18 under its 10-minute cap.

Every count is listed next to its timing on the IQ Tests Hub, so you can choose by how much time you actually have rather than by the name of the format.

Not in the way you would prepare for an exam. The items test reasoning rather than recall, so there is no syllabus to revise and cramming does not move the number much.

What does help is ordinary and boring: a full night’s sleep, a quiet room, a device you are comfortable with, and sitting it when you are alert rather than at the end of a long day. The IQ Test Guide goes through this properly.

Worth knowing before a second attempt: familiarity with the item formats lifts a score on its own, which is a different thing from your reasoning having improved. Regression to the mean explains the rest of the drift.

Scoring happens on submit. There is no queue and no waiting period — your score, your percentile and your domain breakdown are produced immediately, and the certificate is issued in your name.

Save what you want to keep at that point. The result link is private and expires, so the certificate and the report are worth downloading while it is open.

Your responses are scored against a standard distribution rather than as a simple count of correct answers: the average is set at 100 with a standard deviation of 15, which means roughly 68% of people score between 85 and 115.

Like every cognitive assessment, a single score carries a margin of error and is better read as a band than as a point. This is a self-administered online assessment — it is not a clinical or diagnostic instrument, and it is not a substitute for a formal evaluation by a licensed psychologist. IQ Test Accuracy goes through what online testing can and cannot establish.

Your official IQ score, your percentile ranking against the general population, a printable certificate issued in your name, and a performance report broken down by cognitive domain rather than reduced to a single number.

The domain breakdown is the part worth reading twice. Two people can arrive at the same composite from opposite directions — one through strong spatial and abstract reasoning, another through verbal and numerical — and that difference is far more useful than the composite alone.

Your percentile is the share of the population scoring below you. Because scores follow a normal distribution centred on 100 with a standard deviation of 15, a score of 100 sits at roughly the 50th percentile and 115 at roughly the 84th.

You can see the whole distribution on the IQ bell curve, or run your own number through the percentile calculator.

An IQ score only means something alongside the scale it was measured on. IQ Metrics reports on the standard scale — mean 100, standard deviation 15 — which is what the Wechsler tests use. Stanford–Binet uses SD 16 and Cattell uses SD 24, so the same underlying ability produces a different-looking number.

The IQ score converter moves a score between those scales, and IQ comparison puts two scores side by side. Every calculator is collected on the IQ Tools page.

No, and that is deliberate. The three single-domain formats report a percentile for that one ability — not an IQ. Only the four multi-domain formats (Mix, Classical, Timed and Culture-Fair) produce a composite IQ score, because a composite is only meaningful once several abilities have been sampled.

Use a single-domain test to look closely at one ability — for example mental rotation and visual pattern completion — not as a shorter route to an IQ number.

Yes, through the retest page. A retest is arranged by request rather than started instantly: you submit the email address used for the original assessment and the retest is approved from there. Note the stated policy — if a retested score comes out lower than your previous one, no report is issued for it.

Leave time between attempts. Familiarity with the item formats lifts a second score on its own, and an unusually high or low first result tends to drift back towards the average regardless of anything you do — see regression to the mean and IQ over time.

Yes — the Kids IQ Test covers ages 4–17 with age-appropriate items in three age bands, scored against same-age peers rather than against adults. A child’s result is only meaningful compared with others of a similar age.

It is an educational, non-diagnostic experience. It is not a gifted-programme screening tool, and it is not a substitute for a formal assessment by a school psychologist or other qualified professional.

100 is the definitional average, and about two-thirds of people score between 85 and 115. Above 115 places you in roughly the top 16%, and 130 or above in the top 2%.

Beyond about 130 the gap between two scores is often smaller than the measurement error attached to them, so reading 137 as meaningfully better than 133 misreads the instrument. The IQ bell curve shows where each band sits, and average IQ by country explains why national comparisons need to be read with caution.

No. Mensa accepts either its own supervised admission test or approved prior evidence from a supervised, proctored assessment, and no online result qualifies — ours included.

What a well-calibrated online score can tell you is whether sitting the supervised test is likely to be worth your time, which is a genuinely useful thing to know before you book one.

IQ Metrics uses the same bands the home page shows:

• Above 144 — highly gifted
• 130–144 — gifted
• 115–129 — above average
• 85–114 — average, where most people fall
• 70–84 — below average

A band is a convenience for talking about scores, not a category you belong to. A score sitting near a boundary is within the measurement error of the band next door, so 129 and 131 are not meaningfully different despite falling either side of a line. The IQ bell curve shows how thinly populated the outer bands really are.

The score is the position; the percentile is what that position means. An IQ of 115 is a number on a scale. The 84th percentile tells you that 84 people in 100 scored below it — which is usually the part people actually wanted to know.

The IQ Tools page reports four things from a single score at once: percentile, band, rarity, and the range the score realistically sits in. That last one matters most, because a bare number implies a precision the instrument does not have.

The standard scale — mean 100, standard deviation 15 — which is what the Wechsler tests (WAIS and WISC) use, and the scale the IIF certification is issued against.

Check the scale before comparing against a score from anywhere else. Stanford–Binet reports on SD 16 and Cattell on SD 24, and the same underlying ability produces a different number on each. The score converter does the conversion, and IQ comparison puts two scores side by side.

Because it is built from fewer items under a hard clock — 15 to 18 questions capped at 10 minutes, against 40 to 50 items over 20 to 25 minutes on the Classical format. Fewer items means a wider margin of error, so the number is honest as an indication and misleading as a precise figure.

Take the Timed IQ Test when ten minutes is genuinely all you have. If the number is going to matter to you, take a longer format instead.

They are a benchmark for personal insight: which kinds of reasoning come most naturally to you, and where the effort would have to go if you wanted to shift something.

They are intended for personal and educational use. This assessment is not designed or validated for admissions, hiring, or any other high-stakes decision, and should not be used as the basis for one. IQ vs Personality and Can You Improve Your IQ? set out what a score does and does not predict.

Your certificate is issued in your name and shows your official score, your percentile, the date of the assessment and a unique certificate ID. It is formatted for printing and can be downloaded as a PDF.

It is issued under the certification of the International Intelligence Federation, described further down this page, and it is delivered together with the full performance report.

Yes. Your certificate and report are yours to download, print or share as you choose. We never publish a result or attach it to your name anywhere public.

One practical note: the result link itself is private and time-limited, so download or print your certificate and report while it is still open. Once you have the files, nothing depends on the link staying alive.

As a worked example, the illustrative result shown on the Classical IQ Test page is a composite of 114 built from 112 verbal, 108 numerical, 121 spatial and 115 abstract.

That shape is the useful part. The composite tells you where you landed; the four domains tell you how you got there, and they are what shows whether a strength is broad or concentrated in one kind of reasoning.

Download the PDF certificate and the report while your results are on screen. Result links are private and expire for security, so the link is not a store — the files you save are.

If a link has already expired there is nothing to recover from it. You would need to sit the assessment again, or arrange a retest if you are returning to an earlier result.

Yes. Your responses and your score are yours: they are handled confidentially, used to administer the assessment and issue your result, and they are not sold.

Result links are private and expire, so a forwarded link cannot expose someone’s result indefinitely. The full detail is in our Security and Privacy Policy.

Taking a test does not require an account. We collect your responses in order to score them, and the name and email address you provide so that your certificate can be issued and your report sent to you.

The Security and Privacy Policy sets out what is stored, how long it is kept, and how to request deletion of your data.

Result links are private and expire after a period, which is why an older link can come back saying the session has expired. That is intended behaviour rather than a fault: it stops a link that was forwarded or left open exposing a result later on.

If you saved your certificate or report, nothing is lost. Otherwise you can take the assessment again, or use the retest page if you are returning to a previous result.

The International Intelligence Federation (IIF) is the body associated with the certification issued alongside your results. The IQ Metrics assessment was developed in partnership with the IIF, and certificates issued through this site carry IIF certification.

Four domains: verbal reasoning, numerical reasoning, spatial reasoning, and abstract or logical reasoning. Your report shows how you performed in each one rather than collapsing everything into a single number, which is why two people with the same score can have very different profiles.

Formats sample those domains differently. Culture-Fair deliberately uses only the abstract and spatial items, so that reading and arithmetic do not influence the result. How IQ Tests Work goes through each domain and the item types behind it.

Two things, concretely. All eight formats run on one shared scoring engine rather than being eight unrelated quizzes, so a result from any of them is calibrated the same way — the IQ Tests Hub shows what changes between them and what does not.

And results come back as four domains alongside the composite rather than as a single number, which is what makes a score readable instead of merely rankable.

Why Us sets out the wider case, and IQ Test Accuracy is the honest account of what an online assessment can and cannot establish.
