What separates our tests from other IQ tests?
CognitiveIndex offers tests that have been developed by professionals in the fields of psychology and cognitive science with multiple stages of validation that takes months to complete—our goal is to be as accurate as possible.
Our tests have been proven to load on intelligence at a comparable level to proctored tests such as the Weschler Adult Intelligence Scales and Standard-Binet Intelligence Scales.
