The action sequences of respondents in problem-solving tasks reflect rich and detailed information about their performance, including differences in problem-solving ability, even if item scores are equal. It is therefore not sufficient to infer individual problem-solving skills based solely on item scores. This study is a preliminary attempt to…

A more fragmented approach to assessment of global ability concepts than is generally advocated is suggested, based on the assumption that decomposing a complex ability into cognitive components and tracking performance across multiple measures will yield valid and instructionally useful information. Specifications are suggested for designing…

This article examines how psychometric models based on certain assumptions have come to be used counterproductively by many practitioners in ways that limit the kinds of conclusions that can be made. The general problem of the context's influence on performance is discussed, and some implications are drawn. (SLD)

This article presents a model that can be used by local school districts for reanalyzing standardized test results to obtain a more valid assessment of local learning objectives can be used to identify strengths/weaknesses of existing programs as well as individual students. (EGS)

The utility of item response theory (IRT) models in computerized adaptive tests is considered. Measurement questions that have been answered using IRT, and those that might be overlooked because of IRT, are reviewed. Areas in which fuller use of IRT could improve adaptive testing practices are identified. (SLD)

The Presidential Address at the 1986 National Council on Measurement in Education Annual Meeting argues that measurement specialists have tended to set unrealistic aspirations for the role tests play. The conjunctive decision making model is discussed and the use of data in the conjunctive and compensatory decision making models is examined. (JAZ)

The President of the National Council on Measurement in Education replies to his critics. He argues that the concept of measurement error should not be used to make cut-scores more valid and that grade point averages have not been demonstrated to be valid indicators of teachers' subject matter competence.
