This capstone project examines systemic disparities in disciplinary practices at an independent private middle school and proposes a Diversity, Equity, and Inclusion (DEI) intervention to address these inequities. Drawing on Critical Race Theory (CRT) and Restorative Justice (RJ), the project identifies root causes of disparities, including implicit bias, inconsistent policy enforcement, and cultural misunderstandings, which disproportionately affect Black, Latinx, and Indigenous students. The intervention includes a policy guide, professional development workshops, and restorative practices, such as restorative circles and community advisory councils, to build staff cultural competence and foster inclusive relationships. Data-driven decision-making and equity audits are employed to ensure ongoing improvement and accountability. By addressing systemic inequities and interpersonal dynamics, this project offers a replicable framework to reduce disciplinary disparities and promote an equitable and culturally responsive school environment.
