How to accurately measure your IQ

A reliable IQ test uses Item Response Theory (IRT) scoring, which adapts the scoring based on item difficulty parameters rather than simply counting correct answers. Core Brain uses IRT 3PL (three-parameter logistic) scoring — the same statistical framework used by the WAIS and Stanford-Binet — and returns your score with a 95% confidence interval so you know the measurement uncertainty.
