Improving equity in Computer Science (CS) education across multiple dimensions—from enrollment to experience—benefits from the collaboration of classroom teachers and school leaders. This paper presents the findings of an innovative pilot community of practice (CoP) program that brought together cross-functional teams consisting of CS teachers, school counselors, and administrators. These teams met monthly for equity-focused workshops for one school year. In designing the program, we made extensive use of pre-existing materials from affordable, high-quality, research-based programs, demonstrating potential new benefits from sequencing and synthesizing existing programs. Evidence from surveys and interviews shows that the CoP promoted cross-functional learning and fostered collaboration between teachers and administrators that would not have happened without the catalyst of the project. Participants felt motivated by the program, and they generated ideas that turned into actionable projects to promote CS education equity in their various schools. Although this initiative was well received, there are areas which will be improved in subsequent years, including recruitment of schools, the structure of workshops, and evaluation. This pilot demonstrates the role that equity-centered CoPs composed of cross-functional teams can play in achieving systemic improvement of CS education equity.
