In this article, the authors critically synthesize how Critical Race Theory (CRT) as an emerging field of inquiry has been used as a tool of critique and analysis in K-12 education research. The authors point out that CRT has been used as a framework for examining: persistent racial inequities in education, qualitative research methods, pedagogy and practice, the schooling experiences of marginalized students of color, and the efficacy of race-conscious education policy. The authors explore how these studies have changed the nature of education research and stress the need for further research that critically interrogates race and racism in education.
