The present meta-analysis sought to quantify the average degree of aggregated test score distortion due to rapid guessing (RG). Included studies group-administered a low-stakes cognitive assessment, identified RG via response times, and reported the rate of examinees engaging in RG, the percentage of RG responses observed, and/or the degree of…

Twenty-eight studies of grades, over a century, were reviewed using the argument-based approach to validity suggested by Kane as a theoretical framework. The review draws conclusions about the meaning of graded achievement, its relation to tested achievement, and changes in the construct of graded achievement over time. "Graded…

States have moved rapidly over the past 20 years to institute systems of standards and assessments. State assessments in particular take on added importance at the high school level as they are required for graduation by an increasing number of states. Federal legislation mandating testing in high school also serves to increase the stakes and…

The two articles in this special section discuss the use of portfolios in large-scale assessment. Both describe pilot studies of portfolio assessment, pointing out pitfalls and advantages. If portfolios are to realize their potential in assessment and instructional improvement, teachers, students, and the public must receive better information…

Current discussions of the effects of test administration conditions (i.e., testing stakes) and the motivational levels associated with them on achievement test performance are reviewed. Results of a nonexperimental study suggest that, in contrast to a moderate-stakes testing environment, the National Assessment of Educational Progress does not…

Studies of the extent of standardized testing in U.S. schools in the early 1980s to 1990s were reviewed. All show the amount of systemwide testing to be less than two days per year. Methodological issues are explored, and the extent-of-testing estimates are updated to about 1995 through more recent research. (SLD)
