Psychometrics: Computerized Adaptive Testing
This project implements a complete computational framework for CAT, bridging the robust mathematical foundations of Item Response Theory (IRT) with the dynamic, data-driven logic of adaptive algorithms. By continuously selecting the most informative items for each individual, CAT achieves precise ability estimation with substantially fewer questions, reducing testing time by 50–70% while maintaining or enhancing measurement quality. The system integrates core components—from Fisher Information and Bayesian estimation to practical constraints like content balancing and exposure control—into a cohesive, operational engine for next-generation educational, psychological, and professional assessment.
