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,…

Later editions have been intended for a broader audience as the need for understanding what test scores really mean has…

A cursory examination of current measurement texts used in teacher education reveals a treatment of such topics as test reliability, item analysis, and test interpretation based largely upon classical test theory. In the meantime, the landscape of the classroom has been significantly impacted by a growing emphasis on more authentic assessment…

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)

This technical manual is presented to assist those using the Audit of Principal Effectiveness, an 80-statement evaluation instrument designed to determine teachers' perceptions of principals' effectiveness, allow principals to obtain feedback from teachers regarding strengths and weaknesses, and provide a useful tool for researchers studying…

This book is a practical guide for assessing the intended learning outcomes of classroom instruction. It is based on the premise that assessment of student achievement plays a vital role in instruction and that the main goal of assessment is to improve learning. The new title of this sixth edition reflects a shift from major concern with classroom…

This book presents the full array of assessment methods available to the classroom teacher in an interesting and engaging format, broadens the preservice and inservice teacher's understanding of related assessment issues, and places assessment in a meaningful context.

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…
