Categorical growth models describe examinee growth in terms of performance-level category transitions, which implies that some percentage of examinees will be misclassified. This paper introduces a new procedure for estimating the classification accuracy of categorical growth models, based on Rudner's classification accuracy index for item…

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…

Analyzes the three major inferences involved in interpretation of performance assessments: (1) scoring of the observed performances; (2) generalization to a domain of assessment performances like those included in the assessment; and (3) extrapolation to the large performance domain of interest. Suggests ways to improve the validity of performance…

Discusses appropriate ways to prepare students for performance assessments and proposes a list of six guidelines for teaching to performance assessments. The focus is on elementary and secondary education. It is believed that these guidelines will help balance the domain and sample problem. (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)

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)

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 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)

Generalizability of performance-based assessment scores across raters and tasks is examined, focusing on implications of generalizability analyses for specific uses and interpretations of assessment results. Although it seems probable that assessment conditions, task characteristics, and interactions with instructional experiences affect the…

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)

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)

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)

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,…

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)
