Computerized Adaptive Testing Using the Partial Credit Model: Effects of Item Pool Characteristics and Different Stopping Rules.

Dodd, Barbara G.; And Others

Educational and Psychological Measurement, v53 n1 p61-77 Spr 1993

Effects of the following variables on performance of computerized adaptive testing (CAT) procedures for the partial credit model (PCM) were studied: (1) stopping rule for terminating CAT; (2) item pool size; and (3) distribution of item difficulties. Implications of findings for CAT systems based on the PCM are discussed. (SLD)
