Weiss’s work focuses on evaluating programs designed to improve community college students’ chances of achieving academic success. He is also deeply involved in methodological projects intended to improve the quality of random assignment evaluations.
Weiss has led multiple randomized controlled trials in postsecondary education, serving as principal investigator or co-principal investigator on four Institute of Education Sciences (IES)-funded randomized controlled trials of five postsecondary programs: the Learning Communities Demonstration, a student success course, the Developmental Education Acceleration Project, the evaluation of City University of New York (CUNY) Start, and CUNY’s Accelerated Study in Associate Programs (ASAP). Weiss has authored multiple reports and peer-review journal articles on the effectiveness of higher education programs.
In his methodological work, Weiss is currently the principal investigator on an IES methods grant on issues of program effect variation. His methodological work, which has been featured in peer-reviewed journals, includes articles on teacher effects in experiments, measuring school performance, the uncertainty of effect estimators in individually randomized trials, and a conceptual framework for understanding the sources of variation in program effects. Weiss has served as the methods section chair at the Society for Research on Educational Effectiveness.
Weiss has been invited to give presentations at numerous conferences and organizations, including the U.S. Department of Education’s Institute of Education Sciences and the U.S. Department of Labor. He holds a BS and a master’s degree in applied statistics from Cornell University and a doctorate in education policy from the University of Pennsylvania.
