Expert explanations of IQ testing, psychometric theory, scoring models, and how modern intelligence assessments measure cognitive ability
Our IQ test is a full-scale online intelligence assessment built using Item Response Theory (IRT), standard error of measurement (SEM), person-fit analysis, General Ability Index (GAI), and confidence intervals (CI). These psychometric models allow precise measurement of cognitive ability across logical reasoning, spatial intelligence, verbal comprehension, and working memory.
The assessment is calibrated using modern psychometric measurement theory, incorporating IRT calibration, standard error estimation, person-fit validation, and confidence interval modeling to ensure score stability, internal consistency, and resistance to random, guessed, or invalid response patterns.
This IQ test stands apart by applying formal psychometric scoring models, including Item Response Theory (IRT), domain-level factor structure, General Ability Index (GAI) reporting, and continuous reliability monitoring across millions of completed IQ tests.
Unlike simple quizzes or entertainment-based IQ tests, this assessment applies controlled difficulty progression, response-pattern validation, person-fit analysis, and measurement-error modeling to prevent score inflation and reflect true underlying cognitive ability.
We offer different assessment versions optimized for various age groups:
Our test is available in 15+ languages with cultural adaptations to ensure fair and accurate assessment regardless of your cultural background.
Each language version has been carefully adapted and validated to maintain the same level of accuracy across all cultures.
