Portfolios are the centerpiece of Vermont's statewide assessment program in mathematics. Portfolio scores in the first two years were not reliable enough to permit the reporting of student-level results, but increasing the number of readers or the number of portfolio pieces is not operationally feasible.

Since 1988, Vermont has been developing an innovative performance assessment program that relies substantially on portfolios of student work. This interim report presents findings about the reliability of scores from the first statewide implementation of the portfolio program in the 1991-92 school year. The focus is not on program impact as an…

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 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…
