The field of school psychology continues to further embrace a social justice perspective to address systemic racism, privilege, prejudice, and discrimination. To accomplish this mission, school psychologists must ensure that there is a solid literature base that is inclusive and representative of students from minoritized backgrounds. A review of student sociodemographic characteristics was conducted of all articles in four of the primary journals of school psychology from 2010 to 2019 (n = 1,213 articles). Compared to national estimates of school-age sociodemographic distributions, researchers tended to include samples more representative of students identifying as White/Caucasian and underrepresentative of students from low-income backgrounds. Authors rarely included or described participants' sexual orientations and gender identities beyond the binary (female/male). We provide a discussion and recommendations for improving the inclusivity of students from minoritized backgrounds in future school psychology research.
