Cattell-Horn-Carroll (CHC) Theory

The Cattell-Horn-Carroll (CHC) Theory is a comprehensive framework that explains human intelligence by organizing various mental abilities into three levels: broad domains (like reasoning or memory), narrower skills within those domains, and specific test tasks. Developed from research in psychology, it helps understand how different abilities are related and how they influence learning and problem-solving. This model is widely used in educational and psychological testing to assess cognitive strengths and weaknesses accurately.
