Rigorous training for aspiring teachers is crucial for sustainable education globally. This book explores the vital mentorship roles of school leaders in selected Zimbabwean secondary schools. Drawing upon the Framework of Instructional Leadership and the Mutual Benefits Model, this qualitative study delves into the lived experiences of school leaders and trainee teachers. Findings reveal that while school leaders generally view mentoring positively and mutually benefit from the process, challenges like limited training, resource shortages, and lack of collaboration exist. The book proposes a practical framework to enhance mentoring in developing communities, emphasising in-service training, clear guidelines, and adequate resources. This essential resource offers valuable insights for scholars and policymakers in education management, curriculum studies, and professional development.
