The RIOT test is first professional online IQ test.  It is a rigorously developed, professional online IQ test and testing platform for psychologists, researchers, clinicians, employers, institutions, and curious individuals.

The Reasoning and Intelligence Online Test (RIOT) is an IQ test for adults (18+).  It features 15 subtests across six cognitive indices and is administered through a custom-built online platform. Designed for efficiency, the test can be completed in 60 minutes or less.

It measures:

• Verbal Reasoning
• Fluid Reasoning
• Spatial Ability
• Working Memory
• Processing Speed
• Reaction Time

The RIOT IQ:

• Meets educational and psychological testing standards from APA, AERA, & NCME.
• Is based on the Cattell-Horn-Carroll (CHC) model of intelligence
• Was developed by intelligence researcher  Russell T. Warne. Dr. Warne’s research on human intelligence and giftedness is widely recognized. He has published numerous articles in esteemed journals such as Psychological Bulletin and Intelligence. He is also the author of In the Know: Debunking 35 Myths About Human Intelligence, published by Cambridge University Press in 2020.
• Has been reviewed by a diverse expert panel to ensure fairness. Every question in the RIOT IQ Test undergoes a rigorous sensitivity review by an independent panel of experts, including cognitive, educational, and school psychologists. These specialists carefully examine each item to identify and remove potentially biased, distracting, or inappropriate content.  If a concern is flagged, the item is either revised or removed to maintain fairness and accuracy. This comprehensive review process reinforces our commitment to delivering an equitable, scientifically valid assessment for all test-takers.

The RIOT IQ test is built on over a century of IQ and intelligence research, adhering to psychometric standards and rigorous statistical norming procedures. We strive to be the best online IQ test in the world, and to serve as an alternative to gold standards such as the WAIS and Stanford Binet IQ tests.

The RIOT IQ test is normed for native English speakers aged 18 and older, born and residing in the United States. Norming an IQ test establishes a reference point for interpreting scores. First, the test is administered to a large, diverse demographic group. Statisticians then analyze the results to determine the average score and score distribution. These findings create norms that allow individual scores to be compared to the broader population, providing meaningful insight into cognitive ability. All our IQ tests, including our free IQ test, utilize the same norms.

The RIOT is the only online intelligence test that meets all educational and psychological testing standards set by the American Educational Research Association, the American Psychological Association, and the National Council on Measurement in Education.  See the specific standards that we adhere here to.

Screened for Bias and Fairness

The Riot IQ team took rigorous steps to ensure fairness and reduce bias. A diverse panel of experts, including cognitive, educational, and school psychologists, conducted a sensitivity review to identify and remove potentially biased or distracting content related to race, sex, or other demographics. Problematic questions were either revised or removed.  Each question also underwent statistical analysis to detect bias across different characteristics, ensuring that RIOT provides an accurate and equitable intelligence assessment for all test-takers.

Based on the CHC Model

The Reasoning and Intelligence Online Test (RIOT) is built on the well-established Cattell-Horn-Carroll (CHC) model of intelligence, one of cognitive psychology’s most widely recognized frameworks. The CHC model categorizes intelligence into broad abilities, all of which are assessed by RIOT. Decades of research and widespread application in standardized testing validate the CHC model, making it a strong foundation for the RIOT assessment.

IQ Test Range

The RIOT is designed to accurately measure IQ scores between 75 and 145, with corresponding T-scores ranging from 34 to 80. In some cases, scores outside this range may be extrapolated, but they should be considered approximations, especially if they exceed the range by more than 5–10 points.

IQ score & comparisons

After completing the RIOT test, examinees receive an IQ score (with a margin of error) and an interpretation that compares their results to those of other RIOT test-takers and a representative sample of examinees.

15 Subtests, 16 T-Scores

Along with an IQ score, you will be able to more granularly analyze your T-scores for each of the 15 subtests. In psychometrics, each subtest score is referred to as a “T-Score”. Some subtests have more than 1 score. Reaction Time has 2 T-scores: Choice Reaction Time & Simple Reaction Time, hence 16 T-scores.
