What is an IQ test? The IQ test measures a snapshot of a person's mental ability as compared to others of the same age. Some cognitive abilities can be accurately assessed, which is the goal of the IQ test. To measure mental ability legitimately requires standardized and culture-fair questions. Professional IQ tests and those accepted by Mensa, have been screened and validated over many years to be considered reliable instruments. Years of research revealed that high IQ scores are predicators of professional and academic achievement.

This is a sample IQ test meant to provide insight as to the type of thinking skills measured on a real IQ test. The score provided is not a valid IQ score based on a legitimate IQ scale, but rather a percentage based on the number of correct answers and the total number of questions. Answers are fully-explained (unlike most other free IQ tests) when revealed. This example Intelligence Quotient Test includes analogy, anagram, palindrome, serial / sequential reasoning, non-verbal reasoning, inductive reasoning, deductive reasoning, verbal reasoning, spatial visualization, spatial relation, numeric pattern, mathematical reasoning, letter pattern, reading comprehensive, and general world knowledge problems.
