The College Transition Collaborative applies social psychology knowledge and methods to contribute to systemic equity in college completion outcomes, particularly for students of color, first-generation college students, and women in male-dominated fields across the US and Canada. CTC's work helps schools understand how their students experience moments of transition or difficulty, and how psychologically attuned practices–messages, policies, behaviors, and programs–can convey to all students they are valued, respected, and can excel.
