This document describes the Urban Science, Technology, Engineering, and Mathematics Talent Expansion Program (USTEP) partnership between Chicago State University and two City Colleges of Chicago. The program aims to increase the number of underrepresented students entering, pursuing, and graduating from STEM programs through student-centered academic support including cohort classes, workshops, research experiences, and career exploration activities utilizing CSU's local prairie garden. Evaluation results found higher retention and transfer rates and GPAs for USTEP students compared to non-USTEP students at the participating schools.
