WAIS test online

The WAIS is an individually administered test. A psychologist reads instructions, times you, judges open-ended answers to vocabulary and similarity questions, and hands you physical blocks for the Block Design subtest. Some subtests depend on how a person answers aloud, and the examiner decides when to stop.

Pearson does offer telepractice options in which the examiner supervises you remotely, but the examiner is still in control and decides whether the situation is suitable. That is a different thing from a self-service website. Anything that gives you a "WAIS score" after a quiz is producing an estimate and, at best, borrowing the name.

Some online tests are honest about this and describe themselves as WAIS-style. Others use the WAIS name to suggest a validity they do not have. If a site calls itself the official or accredited online Wechsler test and cannot show a link to the publisher, treat it with suspicion.

The WAIS-5 groups its subtests into five areas, each of which gives an index score. Seven of the subtests combine into the Full Scale IQ.

Searches for the WAIS-IV usually ask for the subtests. The WAIS-IV has 10 core subtests, which produce the Full Scale IQ and the four indexes, and five supplemental subtests that an examiner can use as substitutes or to add information. The four indexes are Verbal Comprehension, Perceptual Reasoning, Working Memory and Processing Speed.

Each subtest raw score is converted to a scaled score by comparing it with people of the same age. Subtest scaled scores have an average of 10 and a standard deviation of 3. Subtests then combine into index scores and the Full Scale IQ, which have an average of 100 and a standard deviation of 15. Our guide to the standard deviation explains why those spreads give the percentiles they do.

Because the comparison is with your own age group, a Full Scale IQ of 100 is average at every age. A score of 130 or above puts you in the top 2% or so. The IQ classifications page lists the descriptive labels, and the average IQ page explains why the middle is always 100.

The WAIS-IV had four indexes. The WAIS-5 splits perceptual reasoning into Visual Spatial and Fluid Reasoning, adds new subtests, and was standardised in 2023 to 2024 on about 2,000 people aged 16 to 90. Its Full Scale IQ reliability is reported at .97.

In a counterbalanced study of 186 adults aged 16 to 90 who took both tests, the WAIS-IV averaged 1.9 points higher than the WAIS-5 (Winter, Trudel and Kaufman, 2024). The gap is the Flynn effect at work: people score higher on older norms. It is smaller than the roughly 3 points a decade that earlier studies found. Older WAIS results remain valid records, but the two editions are not interchangeable. Our Flynn effect page covers why.

The WAIS-5 also changed its descriptive labels. Pearson's sample report describes a Full Scale IQ of 111 as "above average", for instance. The labels below are the WAIS-IV ones, and the WAIS-5 manual is the authority on its own.

You need a psychologist who is qualified to give it. In the UK that is normally a chartered psychologist, and in the US a licensed psychologist or neuropsychologist. Assessments are often arranged for a reason: a school or workplace referral, a clinical question such as ADHD or a learning difficulty, or a private request for a gifted-level result. Providers set their own fees and decide what comes in the report, so ask before you book.

If your aim is Mensa membership, a Wechsler Full Scale IQ of 130 is accepted by American Mensa, and the supervised Mensa tests are a separate, shorter route. The Mensa qualifying scores table lists the cut-off for each test.

An online reasoning test can give a rough sense of how you handle puzzles, particularly matrix-style questions like the Matrix Reasoning subtest. It cannot give a Wechsler IQ, because it has no comparable norm group, no supervision and no examiner.

The LifeScore test is built from matrix-style visual reasoning questions, so it resembles one WAIS subtest, Matrix Reasoning, and nothing else. The WAIS also tests vocabulary, spatial construction, working memory and processing speed, which our test does not. It is not the WAIS and not a clinical assessment.

The matrix practice below is in the style of Matrix Reasoning. It is original, and it is there to show you how these questions work.
