2003 MARC Conference

Validity and Accommodations: Psychometric and Policy Perspectives

August 4 and 5, 2003

University of 浪花直播, College Park, 浪花直播

A conference hosted by the Department of Measurement, Statistics and Evaluation and the Center for the Study of Assessment Validity and Evaluation, University of 浪花直播.  Supported by the 浪花直播 State Department of Education.  Organized by Dr. Rebecca J. Kopriva, Dr. David E. Wiley, Dr. Phoebe C. Winter, and Dr. Robert Lissitz, Department Chair, University of 浪花直播.

Summary

Dissatisfaction with the validity of test results for an increasingly diverse population of test takers has led to the widespread use of testing accommodations.  These accommodations adjust testing conditions with the goal of increased validity of scores for accommodated test takers.  Major questions about testing accommodations are

  1. What are the effects of testing accommodations, in general, and of specific accommodations, in particular, on score validity?
  2. Since accommodations are assigned to test takers, are the assignments appropriate, in the sense that other assignments or other accommodations would not improve score validity more?
  3. Are scores resulting from accommodated testing comparable to other scores? If so, in what sense and to what degree?

State and district experts in psychometrics, measurement systems, English language learners, and students with disabilities will pose these questions and others to the conference presenters. It is anticipated that conference presentations will include discussions about:

  1. New psychometric models and concepts addressing the validity and comparability of accommodated and non-accommodated scores.
  2. New approaches to assigning test takers to accommodations.
  3. Legal and policy foundations of accommodation theory and practice.
  4. Methods for evaluating the validity of accommodated scores.
  5. Accommodations in test design and construction: building accessibility into the development of tests.
