This book examines the critical role that teachers play in supporting at-risk student populations to stay in school and successfully complete their graduation requirements. Thompson addresses how high schools may support marginal students in achieving success by the implementation of teacher self-efficacy and a positive classroom environment. The study identifies ways in which administrators at all levels can support teacher’s professional development and student success through reinforced accountability and consistency. The study also addresses how to grow and strengthen students to not only to stay in the traditional school setting, but to ensure the process will prepare students to be academically, socially, and emotionally ready for college and a career. Fostering this environment requires collaboration and teamwork from teachers, administrators, and parents. Students will demonstrate academic achievement when the school environment is positive, equitable, safe and rigorous.
