View a short video interview (9 min., 12 sec.) in which Professor Reckase discusses two basic types of tests, the continuum model (i.e., measuring height and weight) and the domain model (i.e., how much of a curriculum a student has learned). Professor Reckase discusses the advantages of both test types. He also explains why policymakers sometimes place unrealistic demands on test designers, and the compromises that may be necessary to resolve conflicting demands on achievement tests. In addition, Professor Reckase discusses the difficulty of delivering subscores while at the same time keeping the tests short. View the accessible transcript.

About the Lecture Series

The Angoff Lecture Series was established in 1994 to honor the life and work of William H. Angoff, an ETS research scientist who distinguished himself as a prominent contributor in the field of educational measurement in more than 40 years at ETS. During that time, Angoff authored some of the classic publications on psychometrics, including the definitive text "Scales, Norms, and Equivalent Scores," which appeared in Robert L. Thorndike's Educational Measurement (2nd edition).

The lecture series honors Angoff's legacy by encouraging and supporting the relatively nontechnical discussion of public interest issues related to educational measurement.
