Promoting undergraduate engagement is an important and challenging obstacle at large research-focused universities. Thus, the current study evaluated whether a peer-led program of student-geared events could improve engagement among a diverse group of psychology students early on in their degrees. We randomly assigned interested second-year psychology students to participate in the program or to a wait-list. As compared to students who were randomly assigned to the wait-list, students who participated in the program attended more extracurricular events during the year, had higher grades, and reported greater feelings of engagement and enhanced skill learning. These data provide initial evidence that a peer-led program of student events can improve student life for psychology students attending large research-focused institutions.
