Computerized Mastery Testing with Nonequivalent Testlets
Applied Psychological Measurement Volume 16, Number 1, ISSN 0146-6216
A procedure is introduced for determining the effect of testlet nonequivalence on operating characteristics of a testlet-based computerized mastery test (CMT). The procedure, which involves estimating the CMT decision rule twice with testlet likelihoods treated as equivalent or nonequivalent, is demonstrated with testlet pools from the Architect Registration Examination.
