Haertel's argument is that one must "expand the scope of test validation to include indirect testing effects" because these effects are often the "rationale for the entire testing program." The author strongly agrees that this is essential. However, he maintains that Haertel's argument does not go far enough and that there are two additional…

Studied Kentucky's efforts to include students with disabilities in its statewide assessment, exploring the inclusion achieved, the kinds of accommodations offered, student performance, and the relationship between performance and the use of accommodations. Statewide results show that most students were included, but that some scores may not be…

Reports on an ongoing evaluation of the Vermont portfolio assessment program. Indicates that the positive news about the instructional effects of the assessment program are in contrast with the empirical findings about the quality of the data the program has yielded. (SLD)

This study explored the performance of students with disabilities on a field test of the revised New York State Regents Comprehensive Examination in English, the first of two new Regents examinations that almost all students in the state will have to take to obtain a high school diploma.

The 1992-93 school year saw the second statewide implementation of the Vermont portfolio-assessment program, and RAND continued its ongoing evaluation of the program's implementation, effects, and data quality. While the first year's study found evidence of the impact of the assessment program and low reliability of portfolio scoring, this year's…

The results of an evaluation of Vermont's statewide assessment initiative are presented, with information about the implementation of the program, its effects on educational practice, the analytic challenge presented by the portfolio scoring process, the reliability and validity of portfolio scores, and the tensions between assessment and…

The 1992-93 school year was the second year of the implementation of the Vermont assessment program. Evaluation of the 1991-92 year yielded mixed results, with some evidence that the assessment program was having a strong impact on instruction, but other indications that the reliability of the portfolio scoring in both writing and mathematics was…

Since 1988 the Vermont Department of Education has been developing an innovative statewide performance assessment program. In 1990, the RAND Corporation began evaluating the Vermont assessment program, focusing specifically on the portfolio component of its assessment system. This report presents results from the evaluation in the 1992-93 school…
