The Optimal Item Pool Design in Multistage Computerized Adaptive Tests With the p -Optimality Method.

The present study extended the p -optimality method to the multistage computerized adaptive test (MST) context in developing optimal item pools to support different MST panel designs under different test configurations. Using the Rasch model, simulated optimal item pools were generated with and with...
