Nonparametric or kernel regression estimation of item response curves (IRCs) is often used in item analysis in testing programs. These estimates are biased when the observed scores are used as the regressor because the observed scores are contaminated by measurement error. Accuracy of this estimation is a concern theoretically and operationally.…

Using generalizability theory, this study examined both the rating variability and reliability of English as a second language (ESL) students' writing in two provincial examinations in Canada.

This report examines the differences in impact estimates and standard errors that arise when these are derived using state achievement tests only (as pre-tests and post-tests), study-administered tests only, or some combination of state- and study-administered tests.

Students at each grade level were randomly selected to participate in…

The major elements of a test interpretation model which would assist school personnel in presenting standardized test information to the public are presented. The model is a prototype based upon the testing program used in the Oakland, California Public Schools. An outline and sequence of the test score presentation are suggested, including notes…
