Computerized Adaptive Testing Using the Partial Credit Model: Effects of Item Pool Characteristics and Different Stopping Rules.
Peer reviewed Peer reviewed
Dodd, Barbara G.; And Others – Educational and Psychological Measurement, 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)
