This session explores the powerful impact of peer-to-peer leadership in a secondary MTSS framework through the lens of three distinct student-led programs. Participants will discover how Mustang Mentors support freshmen in their academic and social transition to high school through peer mentorship. The presentation also highlights Peer Links, which connects students with and without disabilities across the school day to promote belonging for all students. Furthermore, we will examine how the "Be Nice." team champions mental health awareness to cultivate a proactive and compassionate school climate.
