This study is an evaluation of the psychometric issues associated with estimating objective level scores, often referred to as "subscores." The article begins by introducing the concepts of reliability and validity for subscores from statewide achievement tests. These issues are discussed with reference to popular scaling techniques, classical…

Demands for accountability have seen the implementation of large scale testing programs in Australia and internationally. There is, however, a growing body of evidence to show that externally imposed testing programs do not have a sustained impact on student achievement. It has been argued that teacher assessment is more effective in raising…

This study examines the practical implications of using state tests to measure student achievement in impact evaluations that span multiple states and grades. In particular, the study examines the sensitivity of impact findings to (1) the type of assessment used to measured achievement (state tests or an external assessment administered by the…

This study addresses the sample error and linking bias that occur with small and unrepresentative samples in a non-equivalent groups anchor test (NEAT) design. We propose a linking method called the "synthetic function," which is a weighted average of the identity function (the trivial equating function for forms that are known to be…

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.…

Performance based assessment refers to tasks that require students to construct responses or take actions to demonstrate specific knowledge or skills. Performance assessment tasks appear in a variety of formats, but they focus on higher order skills and are nonroutine, and sometimes loosely structured, in nature. A number of concerns have been…

This paper summarizes an investigation of applications and issues in free response (FR) testing during 1989. It draws on ideas from the results of the National Educational Longitudinal Study 1988 (NELS:88) field test, a seminar series at the Educational Testing Service (ETS), working papers prepared for several FR testing applications, and…

Testing and assessment that are "more authentic" (performance-based or alternative) represent the most pressing issue in education today. Some of the major criticisms leveled at standardized testing are examined, and the advantages and disadvantages of more authentic assessment are reviewed. A general direction for integrating traditional and…

Computer-based testing (CBT) is typically implemented using one of three general test delivery models: (1) multiple fixed testing (MFT); (2) computer-adaptive testing (CAT); or (3) multistage testing (MSTs). This article reviews some of the real cost drivers associated with CBT implementation--focusing on item production costs, the costs…
