Estimating Conditional Standard Errors of Measurement for Tests Composed of Testlets.
Lee, Guemin
Applied Measurement in Education, v13 n2 p161-80 2000
Investigated incorporating a testlet definition into the estimation of the conditional standard error of measurement (SEM) for tests composed of testlets using five conditional SEM estimation methods. Results from 3,876 tests from the Iowa Tests of Basic Skills and 1,000 simulated responses show that item-based methods provide lower conditional SEM estimates than do testlet-based methods. (SLD)
