Key Takeaways

  • IQ tests are standardized tests covering a range of skills such as logical, spatial, classification, analogical, and pattern-driven questions. Although the free online version cannot be compared to the official version of IQ tests available, they give a general, perhaps the somewhat inflated idea of the category to which one belongs.
  • Be advised that online IQ tests are no substitute for official tests administered by professional psychologists.
  • Results are instant and have not been processed with the due diligence expected from a professional. Therefore, treat scores as unofficial.
  • Parents are advised not to use free online tests to diagnose their child’s learning disability.

Where To Get Free IQ Tests Online

If you wish not to spend money or too much time assessing your intellectual prowess, there are some free options online. These will give you at least an indication of your potential IQ; it is best to do the official tests for more accurate results. The following 14 IQ tests are some of the most reliable:

1. Wechsler Adult Intelligence Scale (WAIS)

  • Number Of Questions: 60
  • Time Required: 15 – 30 min

David Wechsler designed this test in the 1950s; they are still widely used to assess a person’s cognitive ability. There are two key areas in the WAIS, namely verbal and performance. With 14 subtests, 7 fall within the verbal arena and 7 within the performance section.

The verbal test considers arithmetic, vocabulary, letter-number sequencing, comprehension, information, similarities, and digit span. On the other hand, performance subsets deal with the arrangement and completion of pictures, block design, object assembly, symbol search, digit symbol, and matrix reasoning.


The free online IQ test based on the Wechsler takes about 15 – 30 minutes to complete but is not as reliable as the official WAIS. The official version can be purchased. Follow the link to do 60 questions of the WAIS, Version 5

Should You Trust Online IQ Scores?

Authentic and professionally administered IQ tests are designed to be: reliable, calibrated to the norm, comprehensive, and professionally supervised.

Adult IQs are relatively stable over time, so if accurately measured, then scores should not vary widely across different tests and times. Allowances should be made for bad mood days, feeling tired days, etc. However, a few online stories of people who have taken multiple tests online report a wide variance in scores, which does not say much about their reliability.

Well-designed tests are calibrated to the population of people the test taker compares themselves to. To reliably know how your IQ compares to the average American, you need to write a test that a sufficiently large and representative sample has written of Americans.

If you are of average intelligence, you should score 100. Also, the test should be normed so that if all Americans wrote the test, 68% of them should score between 85 and 115. There is no guarantee that online tests have been normed against a sufficiently large and representative population.

If you score 100, the tests say that an average IQ may not be reflective of the American average. Also, because the IQ norm of the US population changes over time, well-designed IQ tests need to be updated.

Another reason online test scores may be unreliable is that they lack professional supervision, unlike authentic clinical tests. Nothing prevents online test takers from breaking test rules by accepting help from friends and using calculators and dictionaries.

Are Online IQ Tests Sufficiently Comprehensive?

Since IQ is a numerical summary or average of mental ability, a wide range of cognitive aptitudes need to be accurately assessed to arrive at an accurate representative number. A proper IQ test typically takes 1 – 2 hours and consists of 25 – 50 multiple-choice questions.

Suppose the online test is heavily biased towards verbal reasoning, for example, and only takes 15min to complete. In that case, it may be accurately measuring only one aptitude, not overall IQ. The gold standard of adult IQ testing is the Wechsler Adult Intelligence Scale version 4.

WAIS-IV contains 10 subtests and 5 supplemental tests in 4 main areas of mental ability: perceptual reasoning, word comprehension, working memory, and processing speed.

Are All Online IQ Tests Instant and Free?

Not all online IQ tests are free; a more comprehensive analysis of your results needs to be paid for in certain cases. These are not necessarily instant either, as registration is necessary, and results are emailed.

For example, the official versions of these IQ tests require payment to get the results. The Worldwide IQ Test costs $11.99 to get an exact IQ score and report emailed to you.
