- Summary:
-
The primary purpose of this study was to investigate the appropriateness and implication of incorporating a testlet definition into the estimation of the conditional standard error of measurement (SEM) for tests composed of testlets. The five conditional SEM estimation methods used in this study were classified into two categories: item-based and testlet-based methods. When individual items are used as the fundamental measurement unit, the assumptions required by measurement modeling for tests composed of testlets are violated. Therefore, item-based estimation methods might introduce some magnitude of bias in the estimates of conditional SEMs for tests composed of testlets. In general, the item-based methods provide lower estimates of the conditional SEM along the score scale than do the testlet-based methods. This result is consistent with the previous findings that the reliability of test scores composed of testlets would be overestimated by item-based reliability estimation methods.
