This book shows the extent of parents' involvement in secondary school management, identifies effects of increased parents' involvement on the managerial functioning of Headteachers as well as establishing the perception of parents' involvement in secondary school management. A hybrid theoretical framework of the behavioural science theory and parents-school-relations concept buttressed the study and revealed that parents' involvement in the management of schools support Headteachers in their various roles hence, more parents' involvement was requested for. The Ministry of Education should encourage parents' involvement in the management of public secondary schools; review the role of parents' involvement in secondary school management with a view to giving legal status to the Parents'-Teachers'- Associations. The Perception of parents' involvement in the management of other sectors of education in Kenya should be studied to elaborate of how parents' involvement is perceived. This book suggests that further studies be done to throw more light on parents' involvement in secondary school management, its financial, political, tribal and religious implications for Headteachers.
