Our IQ test is built on decades of cognitive science research and validated psychometric principles
Our cognitive assessment is designed based on the Cattell-Horn-Carroll (CHC) theory of intelligence, which is the most comprehensive and empirically supported model of human cognitive abilities. This theory identifies multiple broad cognitive abilities that contribute to overall intelligence.
The test incorporates elements inspired by established instruments such as the Wechsler Adult Intelligence Scale (WAIS), Raven's Progressive Matrices, and the Stanford-Binet Intelligence Scales. While our online assessment is not a replacement for clinical evaluation, it provides a reliable estimate of cognitive abilities.
Each question type is designed to measure specific cognitive domains, allowing us to provide a comprehensive profile of your intellectual strengths and areas for potential development.
Our test includes five distinct cognitive domains, each measuring different aspects of intelligence
These questions measure fluid intelligence and abstract reasoning ability. You must identify patterns in visual matrices and determine the missing element.
These questions assess quantitative reasoning and the ability to identify mathematical patterns and relationships in number series.
These questions measure crystallized intelligence, vocabulary knowledge, and the ability to understand relationships between concepts.
These questions evaluate your ability to mentally manipulate objects, understand spatial relationships, and visualize transformations.
These questions assess your ability to apply rules, draw valid conclusions from premises, and identify logical fallacies.
Our scoring algorithm takes into account multiple factors to provide an accurate assessment:
The final IQ score is calculated using deviation IQ methodology, which compares your performance to a normalized distribution. This is the same approach used by all major standardized IQ tests.
