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.

The temporal stability and intertask consistency of an eighth-grade mathematics performance assessment and how task similarity affects the ability to generalize results of the assessments were studied with results from 101 eighth graders. Results support the suggestion that large-scale performance assessments be used with considerable caution…

A brief history of developments in the assessment of the reliability of credentialing examinations is presented, and some new results are outlined that highlight the interactions among scoring, standard setting, and the reliability and validity of pass-fail decisions. Decision consistency is an important concept in evaluating credentialing…

Issues pertaining to the quality of performance assessments, including reliability and validity, are discussed. The relatively limited generalizability of performance across tasks is indicative of the care needed to evaluate performance assessments. Quality control is an empirical matter when measurement is intended to inform public policy. (SLD)

Alternatives to multiple-choice tests for teacher licensing examinations are described, and their advantages are cited. Concerns are expressed in the areas of cost and practicality, reliability, corruptibility, and validity. A suggestion for reducing costs using multiple-choice responses calibrated to constructed-response tasks is proposed. (SLD)
