The author asserts that the field of teacher education must begin a critical conversation to better prepare and support teachers in attending to the complexities of racialized identities, experiences, and perspectives of multiracial students in K12 schools. The author offers a review of literature relevant to multiracial students, and draws from the emerging theoretical framework of Multicrit (Harris in Int J Qual Stud Educ 29(6):795-813, 2016) to present monoracism, ahistoricism, colorism and intersectionality to analyze excerpts from three respective research studies. Each excerpt demonstrates an imperative to build a critical understanding of multiracial students within teacher work. The author concludes with implications for future research and practice.
