This paper describes the development of four school self-assessment rubrics, grounded in New York’s Culturally Responsive-Sustaining Education (CR-SE) Framework: (1) Welcoming and Affirming Environment, (2) High Expectations and Rigorous Instruction, (3) Inclusive Curriculum and Assessment, and (4) Ongoing Professional Learning. Designed for 360° input from leaders, teachers, students, and parents, the rubrics provide a continuum that clarifies complex concepts—such as cultural competence, equity, and social justice—while fostering reflection, assessment, and growth. By embedding developmental progressions, they serve as both learning tools and formative assessments. The process of developing and piloting the rubrics illustrates the power of diverse teams to advance equity, offering practical guidance for schools seeking to embed cultural responsiveness meaningfully into daily practice. The rubrics and supporting materials are available at crs360toolkit.org
