What is BrainTypeIQ?
BrainTypeIQ is an online IQ test designed around the CHC model, a theoretical framework used in intelligence assessment and related to tests such as WAIS and WJ.
Based on the CHC model
The test uses the CHC model as its theoretical framework. Scores are calculated from over 1,000 collected responses, after excluding invalid or duplicate responses, using statistical analysis that takes age into account.
