Intelligence test for adults: the WAIS-IV
What is the Wechsler Adult Intelligence Scale IV?
The WAIS-IV is the intelligence test for adults (or adolescents above 16 years of age) which has the greatest scientific validity. It is used to know the characteristics of an adult's cognitive intelligence and to determine if that person is intellectually gifted (for this, personality tests are sometimes needed too when the IQ score is too close to 130).
10 core subtests to evaluate every aspect of intelligence
The WAIS-IV includes 10 core subtests. These subtests are summed to four indexes (the Verbal Comprehension Index, the Perceptual Reasoning Index, the Working Memory Index and the Processing Speed Index) and one Full Scale IQ, which ranges from 40 to 160.
Is there a scientifically valid IQ test for people under 16 years old?
A maximum of 2 hours is usually needed for a short interview and the completion of the WAIS-IV. The next day or later, there is a debriefing session during which a written report with the IQ score, the indexes and an analysis of cognitive functioning is provided.
Can I take the WAIS-IV in French?
Yes, you can take the WAIS-IV in English or in French. If you speak better French than English, if for example you have a broader vocabulary in French, it might be more suitable to use the French version.
