Culture Fair Free IQ Test 2018
Based on the work of Dr. John C. Raven

The reference tool for the evaluation of intellectual potential in 2018

This free IQ test consists in 40 questions of increasing difficulty level. The candidate must choose from a range of symbols to find the one which completes the set. The challenge is to grasp the relevance of the symbols without context and to understand the relationship between them.

This free IQ test is particularly challenging because it assesses the top 25% of the cognitive capacity range. Don't give up!

Used for more than 60 years for children and adults alike in more than a hundred countries, this IQ test evaluates an essential component of intelligence: inductive capacity.

Inductive capacity is defined as a person’s capacity to formulate new concepts when faced with new information, to extract meaning from confusion or ambiguity and to think through complex situations and events in a clear manner.

The gold standard in intelligence tests

This IQ test is thus able to differentiate between individuals according to their capacity for immediate observation and their logical reasoning and determine their learning potential.

Frequently Asked Questions

Marissa, Chief Psychologist since 4 years at IQ Research

Can my child take this IQ test?

Yes. Although it is used most often by adults, this IQ test is valid for children from age 6 and a half to age 16 and a half. The IQ obtained is automatically adjusted to account for age during the normalization phase.

How is the IQ calculated?

After completing the test, your score will firstly be converted according to international standards and correlated to a percentile based on your age. The higher the percentile, the better the performance. For example a percentile of 67 indicates that 67% of subjects achieved a lower score.

Secondly your percentile is correlated with your IQ using the Wechsler scale (standard deviation 15).

By definition, the average IQ is 100. If you exceed 100, you have above-average intelligence and a lower score indicates that, according to a specific measure, you are less intelligent.
