William H. Angoff,

The 15th William H. Angoff Memorial Lecture, "Evaluating the Quality of Accountability Systems: Beyond Reliability and Validity," was delivered in April 2015 by Dr. Brian Gong of the National Center for the Improvement of Educational Assessment. Dr. Gong discussed how the evaluation of accountability systems, including school accountability and educator evaluation, should be treated separately from the evaluation of achievement testing.

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.
