This conceptual article utilizes critical race theory (CRT) to explain how everyday forms of racism--racial microaggressions--emerge in the everyday experiences of People of Color. We provide a framework for understanding and analyzing racial microaggressions that demonstrates how everyday racist events are systemically mediated by institutionalized racism (i.e. structures and processes), and guided by ideologies of white supremacy that justify the superiority of a dominant group (whites) over non-dominant groups (People of Color). To demonstrate the conceptual utility of the framework, we utilize historical and contemporary examples of racial micoraggressions, and offer varied ways to use the framework in critical race research. We argue racial microaggressions can be a powerful "tool" for identifying, disrupting, and dismantling the racism that marginalizes, subordinates and excludes People of Color in and outside of education.
