I am looking for a general intelligence test which meets the following requirements:

  • available online for free
  • there is a table which translates "points" to IQ (I don't want a hidden online evaluation)
  • it should be a reliable test (I am not looking for any sample tests like Mensa Workout)

Perhaps I should add, that I don't want to use the test to measure intelligence. I am a mathematics teacher and just want to have a complete IQ test to develop some problems for my classroom about probability and statistics based on an authentic IQ test-design.

    $\begingroup$ Of possible interest: Public domain scientific intelligence test available for use in research. $\endgroup$ – chl Jan 28 '12 at 20:11
  • $\begingroup$ I doubt that any DIY test will result in high levels of accuracy. These tests cost a lot of money to create and they are fairly elaborate. Self-administering them is, well, kind-of a crazy idea. Just knowing what the test measures gives you an advantage. $\endgroup$ – Indolering Feb 4 '12 at 3:51

Paper IQ Test: EDIT: There is a list of printable tests including an IQ test at http://personality-testing.info/printable/, it looks to be of standard internet IQ test quality...

Here is a printable version of an IQ test developed on this website. It is no where near the quality of a professional IQ test but may be interesting and its internal workings are very visible so it may be useful for education.

Online Test: Try iqtest.dk. It is basically a copy of Raven's Progressive Matrices.

This test is developed with the aim of measuring your Intelligence Quotient (IQ). The test is Culture Fair, i.e. it minimises the effect of cultural variables, such as language, mathematics, etc. The test is based on logic, but is furthermore designed to test learning capability, memory, innovative thinking and the ability to simultaneously address several problems.

The test measures the general intelligence - g.

The calculation of IQ is based on answers from more than 250,000 people.

  • $\begingroup$ Thanks, but I cannot find the table which translates correct questions to an IQ value. $\endgroup$ – Julia Jan 30 '12 at 14:03
  • $\begingroup$ @Julia they specifically say that the correct answers are not published, I suppose to prevent people from "beating" the test. So, it's probably not what you're looking for given that you specifically said "I don't want a hidden online evaluation" $\endgroup$ – Josh Jan 31 '12 at 0:34
  • $\begingroup$ @user189 I feel I had to remove my upvote in light of that fact... sorry! While this is a useful resource, it doesn't really meet Julia's requirements... $\endgroup$ – Josh Jan 31 '12 at 0:36

    $\begingroup$ I don't know the assumptions for this test, but if standard assumptions hold, I think it can be used for the intended purpose. Normally, all questions have equal weight, the average score is 100 IQ points, and each IQ point equals 1/15th of a standard deviation of the distribution. This test will give you a total score in IQ points as well as a percentile score, so you can check if these assumptions are true. $\endgroup$ – Ana Mar 11 '12 at 15:09

    $\begingroup$ Links are broken, going to update them with what I think are the correct ones from the same website. $\endgroup$ – AnnanFay May 13 '17 at 12:37


This webpage includes an answer key and conversion table. The test is fair, valid, and reliable at no cost.

    $\begingroup$ Thanks for sharing. Just to clarify, this test looks like an SAT reasoning test and there is a conversion table (but it is from raw to SAT points, thus, an additional conversion to IQ would be required as well as a discussion of the degree to which it is a reasonable proxy for IQ). Is there any documentation about this test (i.e., copyright, explanation of what the scale was intended to measure, explanation of norm development, IQ correlates, etc). Is it the actual SAT test from 2002? or just a practice test that the organisation has developed? $\endgroup$ – Jeromy Anglim Nov 26 '12 at 0:33

I just found out about ICAR.

The International Cognitive Ability Resource is a public-domain assessment tool which aims to encourage the broader assessment of cognitive abilities in psychology and other social sciences and facilitate neuropsychological assessment in medical research and practice. The collaborators working on this project believe that the best way to achieve this aim is by making it easier for research scientists to employ flexible and unrestricted measures which have been well-validated against one another.


It's designed for researchers and you need to register to learn about what is available and gain access to measures.
