May was a senior statistician and psychometrician on the IES-funded validation of the Vanderbilt Assessment of Leadership in Education (VAL-ED) involving over 300 schools nationwide. He was also the primary author on Using State Tests in Education Experiments: A Discussion of the Issues, from the Institute of Education Sciences, a National Center for Education Evaluation technical methods report on the use of state test scores in education experiments from the Institute of Education Sciences. Since 2003, May has taught advanced statistics and research methods courses to graduate students at the University of Pennsylvania and the University of Delaware. As a leader for measurement studies, May works closely with Rebecca Maynard, Horatio Blackman, Sara Chapman, Kalyn McDonough, Kati Tilley and Jim O’Toole on tasks that include survey development, pilot design, data collection and analysis, and fielding the main survey.
