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)

Eighth grade teachers in three local school districts helped customize two standardized norm-referenced tests for ninth graders to investigate effects of deleting some items and adding locally constructed items. Results indicate that percentile ranks for the customized tests could be very different from those for the complete test. (SLD)
