This study reports on early program retention in a multi-component undergraduate science, technology, engineering, and mathematics (STEM) scholar program aimed at diversifying STEM at a large, research-intensive, predominantly White university. The authors drew on London and associates' STEM Engagement Framework to determine what factors are related to remaining in the program through the first two years. Results indicate that having a high scientific identity and reporting fewer instances of discrimination increased the likelihood of remaining in the program. Black students were somewhat more likely than the other underrepresented racially minoritized (URM) groups to remain in the program and were as likely as non-URM participants to remain enrolled in the program.
