Take The Test

There are many online intelligence tests available - with varying levels of quality. We have provided you with a list of our team's picks for best free IQ tests.

The most important thing when looking for the best free IQ test was that they are 100% free. Many providers say their IQ test is free, but then require you to pay once you start the test.

Another important thing we looked at was whether or not the provider required registration before taking the IQ test. This can be annoying and will usually result in follow up emails and offerings that no one wants.

An IQ test is an assessment that measures a person's cognitive abilities and provides a score that is meant to serve as a meaure of that person's intellectual ability. The IQ test is one of the most commonly used psychological tests.

IQ scores are placed on a scale where 100 is considered “average” intelligence, and each standard deviation is 15 points above or below that. It is thought that about two-thirds of a given population is within one standard deviation of the mean, or between IQ 85 and IQ 115.

There are many different tests used for measuring IQ. No one intelligence test is universally accepted as the “official” test, although the Wechsler Adult Intelligence Scale and the Wechsler Intelligence Scale for Children are the most commonly used individual intelligence tests. 

Some intelligence tests are not based on the Wechsler model. Other IQ tests may base their questions on one of the following formats:

  • Stanford–Binet Intelligence Scales
  • Woodcock–Johnson Tests of Cognitive Abilities
  • Raven's Progressive Matrices
  • Cattell Culture Fair III
  • Reynolds Intellectual Assessment Scales
  • Differential Ability Scales
  • Das–Naglieri cognitive assessment system

To simplify – an IQ test is a type of test that will test your intelligence quotient (IQ). There are many different kinds of IQ tests that you can take. Our free IQ test listed above is a great place to start.

As there are many different individual Intelligence Quotient tests available, it is difficult to list a definitive description of test content. The following is based on the Wechsler Adult Intelligence Scale (WAIS), which is the most widely used individual IQ test.

The WAIS-IV (4th Edition) identifies four index scores which represent the major components which make up intelligence:

  • Verbal Comprehension Index
  • Perceptual Reasoning Index
  • Working Memory Index
  • Processing Speeds Index

Collectively, these four main index scores are comprised of 15 subtests, 10 of which are considered “core” subtests. They are organized as follows:

Verbal Comprehension Index of IQ Tests

The Verbal Comprehension Index Score is made up of three core subtests and one supplemental. Core subtests are in bold:

  • Similarities- This subtest presents two words which represent common concepts or objects, and asks the test taker to describe ways in which they are similar. This is to measure formation of verbal concepts and reasoning.
  • Vocabulary- The test taker is asked to name an object based on a picture, and to define words based on an oral or visual representation. This is to measure word knowledge and formation of verbal concepts.
  • Information- The test taker is asked to answer questions drawn from a wide range of general topics. This is to measure skills at acquiring, retaining, and retrieving general facts and information.
  • Comprehension- The test taker is asked to answer questions based on knowledge of generalized principles as well as social situations. This is to measure the ability to use past experiences to form practical understanding and judgement.

Perceptual Reasoning Index of IQ Tests

The Perceptual Reasoning Index Score is made up of three core subtests and two supplemental. Core subtests are in bold:

  • Block Design- Within a specific time limit, the test taker will view a picture and a model, or just a picture, and recreates the design using blocks. This is to measure the test taker’s ability to analyze and synthesize visual stimuli.
  • Matrix Reasoning- The test taker will view an incomplete matrix or series, then selects which response option he or she thinks best completes this matrix or matrix series. This is to measure broad visual intelligence,  fluid intelligence, spatial and classification ability, understanding of part-whole relationships, perceptual organization, and simultaneous processing.
  • Visual Puzzles- Within a specific time limit, the test taker will view a completed puzzle, and select three options which can be used to reconstruct the same puzzle. This is to measure nonverbal reasoning ability, as well as the ability to analyze and synthesize visual stimuli.
  • Figure Weights- Within a specific time limit, the test taker will view a scale which  has missing weight, and will select the response that would balance the scale. This is to measure analogical and quantitative reasoning.
  • Picture Completion- Within a specific time limit, the test taker will be shown a picture or pictures with an important missing part. He or she will choose the answer choice which identifies the part that is missing. This is to measure concentration, visual organization and perception, and recognition of essential visual details of an object.

Working Memory Index of IQ Tests

The Perceptual Reasoning Index Score is made up of two core subtests and one supplemental. Core subtests are in bold:

  • Digit Span- The test taker is read aloud a sequence of numerals and recalls them in the same order they were initially read. They might also be asked to recall them in the reverse order, or to provide the numbers in ascending or descending order. This is to measure mental manipulation, working memory, rote memory and learning, encoding, and attention.
  • Arithmetic- Within a specific time limit, the test taker will mentally solve a number of arithmetic problems. This is to measure concentration, mental manipulation, short term memory, long term memory, attention, mental alertness, and numerical reasoning ability.
  • Letter-Number Sequencing- The test taker is read aloud sequences of numbers and letters and will recall the letters in alphabetical order, and recall numbers in ascending order. This is to measure mental manipulation, sequential processing, concentration, attention, short-term auditory memory, and memory span.

Processing Speed Index of IQ Tests

The Processing Speed Index Score is made up of two core subtests and one supplemental. Core subtests are in bold:

  • Coding- The test taker will copy symbols which are paired with numbers within a specific time limit, using a paper key. This is to measure learning ability, processing speed, visual perception, and visual scanning ability. The test taker will complete this subtest using the same paper key as was provided to them. 
  • Symbol Search- Within a specified time limit, the test taker will scan a search group, and will indicate whether any of the symbols in the target group matches the search group. This is to measure short-term visual memory, processing speed, visual-motor coordination, visual discrimination, cognitive flexibility, and speed of mental operation. The test taker will complete this subtest using a provided response booklet.
  • Cancellation- Within a specific time limit, the test taker will scan an arrangement of shapes, marking specific target shapes. This is to measure visual selective attention, processing speed, vigilance, visual-motor skills, and perceptual speed. The test taker will complete this subtest using a provided response booklet.

Since there is not one governing body or organization that gives IQ tests, there are a lot of different ways to take an IQ test.

Test Administration 

There is no one way to administer an IQ test, because they are all different. In general, IQ tests are administered one-on-one, with a trained psychologist. 

Due to the large number of subtests and questions in many IQ tests, these tests can sometimes take a while and breaks are given to break up the testing day.

Some reasons for taking an IQ test could fall in the following categories:

  • Employers may test potential candidates for a position
  • The military may use intelligence tests to determine new recruit positions
  • Schools may administer tests to determine placement in a special education program
  • Private schools may use test results to determine admittance
  • An individual might simply be curious about his or her IQ or want to get into an organization like Mensa. Take a Mensa practice test.

IQ Test Fees

Intelligence test fees for in-person IQ tests can vary widely, due to the different kinds of tests and reasons for taking them.

In general, you can expect to pay between $0-$200 to take the test. If you are taking it as a requirement for an employer, the military, or school, you may be compensated for your fees.

Your IQ score will depend largely on which test you are taking. In general, ranges are as follows:

IQ Score Range  WAIS-IV Classification 
 130+  Very Superior
 120–129  Superior
 110–119  High Average
 90–109  Average
 80–89  Low Average
 70–79  Borderline
 69 and below  Extremely Low

Mensa is the oldest and largest high IQ society. Mensa membership requires an applicant to score at or above the 98th percentile on an approved intelligence test.  

Mensa is managed locally by each country's local chapter. In the United States, the Mensa chapter accepts test scores from about 200 different standardized tests (all of which require a neutral and qualified testing environment in a traditional environment).  

The American Mensa group does not accept any online test scores. The American Mensa chapter accepts the following tests:

  • Cognitive Abilities Test (CogAT) - CogAT Practice Test
  • Differential Ability Scales (DAS)
  • Differential Ability Scales - Second Edition (DAS-II)

What is a good IQ score?

About 50% of the population's IQ test scores are average. The average score for the IQ test is determined to be 100. So any score over 100, you would be considered above average. Take our free IQ test to see how you stack up.

Who has the highest IQ ever?

Marilyn vos Savant has the highest IQ score recorded, according to the Guinness Book of Records. She recorded a score of 228 at the age of 10.

To put this in perspective, only 0.5% of the population has scored above 140 on an IQ test.
