Wonderlic publishes no IQ conversion. How to estimate one from published norms, why the popular formulas disagree, and why any estimate is a range rather than a measured IQ.
You can practice for an IQ test, but you cannot study your way to a higher IQ. What practice changes, why the gain is not intelligence, and how to prepare fairly.
You can take an IQ test with a psychologist, through a public school, at a university training clinic, at a Mensa session or online. Here is what each gives you and how to choose by what you need the score for.
Pearson lists 45 minutes for the Full Scale IQ on the WAIS-5 and 15 to 30 minutes for the WASI-II, and American Mensa says one to two hours (both read October 2026). Times for each test.
IQ scores sit on a normal curve with an average of 100 and a standard deviation of 15. The share of people in each band, why tests build the scale that way, and where real data fit it less well.
IQ scores rose across the twentieth century, which makes old test norms easy to beat. What studies found on the size, the possible causes and the declines in some recent samples, and what it means for your score.
IQ can rise a little, mostly through years of education. Brain-training games show no reliable gain, and a retake score reads high on average. What controlled studies found, with sources.
An IQ percentile compares you with a test's norm group. It does not count right answers. A score-to-percentile chart, the calculation, and why your percentile is a range.
Abstract reasoning means finding the rule behind patterns you have not seen before. What it is, everyday and test examples, how it relates to fluid intelligence and IQ, and why the UCAT dropped its section.
IQ and emotional intelligence are measured in very different ways. What each score means, how much they overlap, what research says each predicts at school and work, and where the popular EQ numbers come from.
The Wechsler Adult Intelligence Scale, now Pearson's WAIS-5 from 2024, is a one-to-one clinical IQ test. What changed from the WAIS-IV, what it costs, and why a free online WAIS quiz is not the real test.
The Stanford-Binet Intelligence Scales, Fifth Edition (Roid, 2003) is a one-to-one clinical IQ test with 10 subtests and five factors (PRO-ED). How it is given and scored, and why online quizzes differ.
A full IQ test such as the WAIS-5 (Pearson, 2024) samples five abilities and combines them into one score. Raven's matrix test uses a single type of item (APA task force, 1996).
Raven's Progressive Matrices are nonverbal reasoning tests in which you pick the piece that completes a pattern. Scores are compared with an age-based norm group, and the test uses only one kind of puzzle.
Calculated from the WAIS-5's 0.97 reliability (2024), a clinical IQ score has a 95% range of about 5 points either side. Online tests vary, and most free quizzes publish no data.
Fluid intelligence is the ability to reason and solve new problems without relying on what you already know (PNAS, 2008). Learn how it differs from crystallized intelligence and how it is measured.
The average IQ is 100 because tests are scored that way: the norming sample's mean is set to 100 and the standard deviation to 15 (APA, 1996). Learn what the score bands and their labels mean.
