Psychometrically linking a state criterion-referenced test (CRT) and a norm-referenced test (NRT) to yield NRT information through the CRT was studied with samples of 1,500 to 3,000 elementary school students per subject and grade level in Connecticut. A CRT/NRT link can create a focused and coherent assessment system. (SLD)

Four main approaches to customized testing are described, and their resulting scores' valid uses and interpretations are discussed. Customized testing can yield valid normative and curriculum-specific information, although cautious application is needed to avoid misleading inferences about student achievement. (SLD)
