About

About IQTest EN

A reference site about intelligence testing, with a short free test attached. Here is what it is for and how it pays for itself.

IQTest EN exists because the search results for almost every question about IQ are dominated by pages that answer the question badly. Reference tables circulate without sources or dates. Free tests turn out to be free up to the moment the score appears. Sites that will not say what norm group they used present percentiles as though they meant something.

None of that is hard to do better. It mostly requires being willing to publish numbers that are less flattering than the alternatives.

What is here

A free ten-question reasoning test that reports a band rather than an invented number, with every answer explained.

Reference charts generated from the normal distribution rather than copied from other sites, each stating its assumptions.

Long explainers on what an IQ score is, how it is calculated, what it predicts and where the evidence stops.

A page each on the main cognitive tests — Mensa, Raven, WAIS, WISC, Wonderlic, CogAT, Stanford–Binet, culture-fair.

Side-by-side comparisons of the best-known online tests, with our position on them stated on the page.

What we will not publish

• Invented statistics. No fabricated taker counts, no accuracy percentages nobody could verify, no celebrity IQ figures presented as measurements.
• A single number from a ten-item test. The band is what the test supports.
• Percentiles calculated from our own traffic and presented as population percentiles. They would be higher and they would be wrong.
• Accuracy guarantees. Nobody can guarantee this and the claim is a marketing sentence.
• Claims that any online test qualifies anyone for Mensa. None do.

How this is funded

The test is free and there is nothing to buy on this site. We link to iq-test.io as the longer free test we recommend, and we say so on every page where it appears, including in our own comparison articles where we name what competitors do better.

You should read the reviews section knowing where we stand. We think stating it plainly on the page is more useful than a disclosure buried in a footer.

Who writes it

A small editorial team. Every reasoning item is solved independently by two people before publication, every number in a reference table is traced to a named source or generated from the distribution, and where the research is contested we say so on the page rather than picking the tidier answer.

We are not psychologists and nothing here is a clinical opinion. Where a question needs one, the pages say so and say what kind of professional to ask.

The full editorial policy is a page of its own.
