Our IQ Test Methodology
Our methodology uses original browser-scored items, four cognitive domains, a transparent raw-score mapping, and clear limits.
Key Takeaways
- The test is inspired by public psychometric ideas and the open ICAR framework described by Condon and Revelle in 2014, but the shipped items here are original.
- The four domains are abstract, verbal, numerical, and logical reasoning. Spatial ideas appear inside visual matrix items.
- The norming table is research-informed but not locally standardized, so every result is shown as an estimate with a confidence range.
Score Context
This guide is part of the Rice Purity Hub IQ knowledge cluster. It explains the topic in plain language, uses standard psychometric terms, and links back to the free IQ test so readers can compare ideas with a private browser-scored estimate.
Limits And Clinical Use
IQ scores use a normal distribution with a mean of 100 and a standard deviation of 15. Percentiles describe how a score compares with a norm group, not a person's worth, creativity, kindness, or future.
How This Connects To The IQ Test
Online tests can be useful for self-reflection, but they are not clinical assessments. A licensed psychologist must administer instruments such as the WAIS, Stanford-Binet, or WISC when results affect diagnosis, placement, or accommodations.
