The engagement of teachers as raters to score constructed response items on assessments of student learning is widely claimed to be a valuable vehicle for professional development. This paper examines the evidence behind those claims from several sources, including research and reports over the past two decades, information from a dozen state…

The accuracy of statistics based on performance assessments that represent percentages of students reaching standards is explored using data from a large-scale performance assessment, the Maryland School Performance Assessment Program. Results with students in grades 3, 5, and 8 support the accuracy of pooling results to produce the statistics.…

Conceptual, practical, and logistical issues in the development of science performance assessments (SPAs) are discussed. The conceptual framework identifies task, response format, and scoring system as components, and conceives of SPAs as tasks that attempt to recreate conditions in which scientists work. Developing SPAs is a sophisticated effort…

The effects of performance assessment on student learning were studied in third grades in three suburban schools and matched control schools. Performance measures did not produce clear and immediate improvements in student learning, but some positive changes were seen in mathematics. (SLD)

The application of generalizability theory to the reliability and error variance estimation for performance assessment scores is discussed. Decision makers concerned with performance assessment need to realize the restrictions that limit generalizability such as limitations that lead to reductions in the number of tasks possible, rater quality,…

If annual performance assessments are to yield results that can be compared from year to year, many technical problems must be addressed. It is essential that tests to be equated measure the same construct. Methods of equating performance assessment scores, ways of equating system assessments, and standard setting are discussed. (SLD)

A newly developed performance standard-setting procedure, termed iterative judgmental policy capturing (JPC), is applicable to assessments composed of distinct multidimensional exercises. The procedure is described, and results are reported from the application of JPC in a study involving a panel of 20 teachers and 6 performance exercises. (SLD)

The extent to which performance assessments can have unintended and undesirable consequences is not yet clear, but preliminary evidence suggests several issues of bias and fairness. Among these is the sheer difficulty of scoring complex performance assessments, as Vermont's experiences with portfolio assessment illustrate. (SLD)

The rise of criterion-referenced measurement from 1970 to 1984 was an important period in test development. Since 1984 there has been less research published on criterion-referenced measurement, but there is ample evidence that the concept remains important, especially in the authentic measurement and performance assessment movements. (SLD)

Some unfinished issues relating to achievement test theory that seemed implicit in the basic idea of criterion-referenced testing are reviewed, recognizing their importance in current studies of authentic assessment and performance-based tests. The future of performance-based evaluation is explored. (SLD)

The implications for educational and employment testing of recent measurement, social, and policy issues are compared and contrasted. Changes are proposed relative to technical conceptualization of assessment, an increased focus on performance-based evaluation, and expanded expectations and uses of assessment. (SLD)

An example application of portfolio assessment was developed and the model and estimates of reliability derived from the literature were then used to estimate the characteristics of an operational large-scale portfolio assessment program. Costs were estimated to put results in a realistic context. (SLD)

Results are presented from a study of portfolio use for large-scale assessment in the Pittsburgh (Pennsylvania) public schools that are more encouraging for the use of this form of assessment than many other studies have been. Requirements for the psychometric integrity of portfolio assessment are discussed. (SLD)

The testing practices and tests described in the preceding articles are reviewed and compared. This cross-cultural examination identifies some issues that are common to the United States and Europe: (1) the emphasis on performance tasks, (2) the accommodation of language minorities, and (3) concerns about gender differences. (SLD)

How portfolio-based conclusions about student learning might be used to communicate with audiences outside the classroom is explored. Procedures and criteria for investigating validity in portfolio use are discussed. Ten portfolios from an eighth grade language arts class are used as an example. (SLD)
