While national initiatives such as CS10K have expanded efforts to prepare high school computer science (CS) teachers, many educators report limited opportunities to engage in sustained professional learning that emphasizes collaboration, mentoring, and instructional development. In response to this persistent gap, our team developed MENTORS in CS, an equity-focused peer mentoring program designed to support high school teachers within their first three years of teaching CS. Over four years, the program has reached more than 100 educators across the United States, with participants reporting increased teaching confidence, commitment to CS education, and a stronger sense of professional belonging. This tutorial will introduce participants to the structure, practices, and materials that underpin the MENTORS in CS program, with the goal of supporting attendees in designing or enhancing their own mentoring initiatives. Participants will engage in three structured activities: (1) analyzing sociocultural and educational data to inform program design tailored to specific teacher communities; (2) exploring mentoring-focused community of practice activities that promote equity and pedagogical growth; and (3) reviewing and applying tools that support goal setting aligned with the CSTA Standards for CS Teachers. The session will also include brief framing presentations, opportunities for peer exchange, and access to a comprehensive implementation guidebook. This tutorial is intended for teacher educators, university faculty, and leaders of K–12 CS professional learning communities. Attendees will leave with practical strategies, adaptable resources, and a clearer understanding of how peer mentoring can contribute to a more supported, confident, and sustained CS teaching workforce.
