Dr. Jason Bryer is currently an Assistant Professor in Data Science and Information Systems at the City University of New York. Additionally, Dr. Bryer is a consultant with Cornell University where he has developed a research and data collection platform for New York State’s Office of Special Education (https://data.osepartnership.org). Prior to joining CUNY, he was Executive Director at Excelsior College where he has served as Principal Investigator of the FIPSE First in the World grant to develop and research the Diagnostic Assessment and Achievement of College Skills along with supporting research and evaluation of other grants at the institution. Dr. Bryer’s research interests include quasi experimental designs with an emphasis in propensity score analysis, data systems to support formative assessment, and the use of open source software for conducting reproducible research. He is the author of over a dozen R packages, including three related to conducting propensity score analyses. When not crunching numbers, Jason is a wedding photographer and proud dad to three boys.

The Diagnostic Assessment and Achievement of College Skills is a diagnostic assessment designed to help students transition to college. DAACS provides personalized feedback about students’ strengths and weaknesses in terms of key academic and self-regulated learning skills, linking them to the resources to help them be successful students.
This project supports the implementaion of Positive Behavioral Interventions & Supports (PBIS) in New York State. PBIS is a systems approach to creating and maintaining positive school climates where teachers can teach and students can learn. This evidence-based framework emphasizes preventing school discipline problems.
