In this article, Tara Yosso, William Smith, Miguel Ceja, and Daniel Solorzano expand on their previous work by employing critical race theory to explore and understand incidents of racial microaggressions as experienced by Latina/o students at three selective universities. The authors explore three types of racial microaggressions--interpersonal microaggressions, racial jokes, and institutional microaggressions--and consider the effects of these racist affronts on Latina/o students. Challenging the applicability of Vincent Tinto's three stages of passage for college students, the authors explore the processes by which Latinas/os respond to racial microaggressions and confront hostile campus racial climates. The authors find that, through building community and developing critical navigation skills, Latina/o students claim empowerment from the margins. (Contains 14 notes.)
