The authors examined whether the perception of the university environment mediated the relationship between ethnic identity and persistence attitudes of Latino college students. Participants were 175 Latino college students who attended a primarily White university. The results supported the hypothesized mediating role of the university environment. Higher Latino ethnic identity was associated with perceiving a more negative university environment and feeling less committed to finishing college. In turn, perception of a negative college environment was associated with feeling less committed to finishing college. When perception of the university environment was removed, no significant relationship was found between ethnic identity and persistence attitudes, indicating that it is the perceived context that influences Latino college students' persistence attitudes.
