The validity of interpretations of National Assessment of Educational Progress (NAEP) achievement levels is evaluated by focusing on evidence regarding three types of discrepancies: (1) between standards; (2) among descriptions of achievement levels; and (3) between assessments and content standards. All of these discrepancies raise serious…

The contribution of item response theory to the validity of interpretations of achievement test results is reviewed in the context of four applications. The applications include construction of scales for achievement tests, test construction, development of customized tests, and investigation of the influence of instruction on achievement tests.…

The adequacy of linking statewide standardized test results to the National Assessment of Educational Progress by using equipercentile equating procedures was investigated using statewide mathematics data from four states. Results suggest that the linkings are not sufficiently trustworthy to make comparisons based on the tails of the distribution.…

Ten states participated in a cross-state scoring workshop in 1991, evaluating writing from elementary school, middle school, and high school students. Correlation of scores assigned by readers from one state with those from readers from another state were generally quite high. Implications for defining common standards are discussed. (SLD)

The following ways of linking results from distinct assessments to use them for multiple purposes are reviewed: (1) equating; (2) calibration; (3) statistical moderation; (4) prediction; and (5) social moderation. The characteristics of these methods, their requirements, and the comparative inferences they support are described. (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)

The nature of admissions tests and their intended uses are reviewed. Evidence regarding the validity of tests, their contributions to admissions decisions, the effects of coaching, and possible bias in the predictive meaning of test scores for women and minorities are discussed. (Author/SLD)
