Since its introduction as an analytic and theoretical tool for the examination of racism in education, CRT scholarship has proliferated as the most visible critical theory of race in educational research. Whereas CRT’s popularity can be viewed as a welcome sign, scholars continually caution against its misappropriation and overuse, which dilute its criticality. We draw from the cautionary ethos of this canon of literature as the impetus for examining CRT’s terrain in social studies education research. Starting from Ladson-Billings’s watershed edited CRT text on race and social studies in 2003, this study provides a comprehensive theoretical review of scholarly literature in the social studies education field pertinent to the nexus of CRT, racialized citizenship, and race(ism). To guide our review, we asked how social studies education scholars have defined and used CRT as an analytic and theoretical framework in social studies education research from 2004 to 2019, as well as how scholars have positioned CRT within social studies education research to foreground the relationship between citizenship and race. Overall, findings from our theoretical review illustrated that contrary to the proliferation of CRT in educational research, CRT was slow to catch on as a theoretical and analytic framework in social studies education, as only seven of the articles in our analysis were published between 2004 and 2010. However, CRT emerged as a viable framework for the examination of race, racism, and racialized citizenship between 2011 and 2019, with a majority of these studies emphasizing (a) the centrality of race as a core tenet of CRT, (b) idealist interrogations of race, (c) the perspectives of teachers of color and White teachers in learning how to teach about race, and (d) the role of race and racism in curricular analyses that serve as counternarrative to the master script of the nation’s linear social progress in social studies education.
