About the WAIS-style IQ test
The Wechsler Adult Intelligence Scale (WAIS) is the most widely used IQ test for adults in clinical psychology, now in its fourth edition (WAIS-IV). The IQ EXAM WAIS-style assessment mirrors the WAIS-IV's four-index structure online: 20 questions spread across Verbal Comprehension, Perceptual Reasoning, Working Memory, and Processing Speed. You'll get a Full Scale IQ (FSIQ) score on the standard 100-point scale plus a per-index profile.
Whether you want to estimate your Full Scale IQ, prepare for a clinical Wechsler assessment, or compare your cognitive profile across the four index scales, this WAIS-style intelligence test gives you results in 15 minutes. Free to take, no signup required to start.
You'll also see this assessment called the Wechsler Adult Intelligence Test, the WAIS-IV, the older WAIS-III (WAIS 3, also written "wais iii"), or simply a Wechsler IQ test online. All those names refer to the same Wechsler lineage; this WAIS practice test is built on the four-index framework that has been continuous from WAIS-III through to WAIS-IV. It works as a WAIS practice test before a clinical Wechsler administration, or as a stand-alone Wechsler intelligence test that hands you a Full Scale IQ in 15 minutes.

Frequently asked questions
What is the WAIS test?
The Wechsler Adult Intelligence Scale (WAIS) is the most widely used adult IQ test in clinical psychology. The current edition WAIS-IV measures four index scales (Verbal Comprehension, Perceptual Reasoning, Working Memory, Processing Speed) that combine into a Full Scale IQ (FSIQ).
What is FSIQ?
FSIQ stands for Full Scale IQ — the composite score produced by the Wechsler scales. It's a weighted average across the four index scales and uses the standard 100-point IQ scale (SD 15).
What is a good Full Scale IQ (FSIQ) score?
On the 100-point scale, an FSIQ of 100 is exactly average and about two-thirds of adults score between 85 and 115. An FSIQ above 130 is in the gifted range (top ~2%). Your IQ EXAM report shows your FSIQ, percentile, and the four index scores.
What is the average IQ?
The average IQ is 100 by definition — the Wechsler scales are centred on 100 with a standard deviation of 15, so most people (about 68%) score between 85 and 115.
Is the WAIS test free?
Yes — the WAIS-style assessment on IQ EXAM is completely free to take. The detailed report and certificate are an optional unlock.
How long does the WAIS test take?
About 15 minutes. There are 20 questions of progressively increasing difficulty, distributed across the four Wechsler index scales.
What's the difference between WAIS and Stanford-Binet?
Both produce a deviation IQ on the 100-point scale. WAIS uses 4 index scales focused on adult cognition; Stanford-Binet 5 uses 5 factors that work across a wider age range.
Is this an official WAIS test?
No — IQ EXAM is an online assessment inspired by the WAIS-IV index structure. The official WAIS is administered one-on-one by a licensed psychologist.
Do I get an IQ certificate?
Yes — after the test you can unlock an official IQ EXAM certificate showing your WAIS-style FSIQ, percentile, and the four index scale scores.
What's the difference between WAIS-III, WAIS-IV, and "WAIS 3"?
WAIS-III (often searched as "WAIS 3" or "wais iii") was the third edition of the Wechsler Adult Intelligence Scale, published in 1997. WAIS-IV (2008) is the current edition and what most modern clinical reports use. Both rely on the same four-index Wechsler framework (Verbal Comprehension, Perceptual Reasoning, Working Memory, Processing Speed), so this WAIS-style test gives a useful estimate against either edition's deviation-IQ norms.
Can I take a Wechsler IQ test online as a WAIS practice test?
Yes — this is exactly that: a Wechsler IQ test online, built on the WAIS-IV index structure, that doubles as a WAIS practice test for anyone preparing for a clinical Wechsler administration. It's not a substitute for an in-person assessment, but it gives you a useful Full Scale IQ estimate and a feel for the kind of reasoning and processing the official WAIS / Wechsler adult intelligence test measures.
