This book tells how a secondary school can be improved without resorting to radical approaches. It is based on the author's experiences and on the programs at Concord High School, Wilmington, Delaware. Emphasis is placed on organizing a secondary school that can initiate changes from the "inside," by the educators on the firing line. Containing practical and simple procedures for developing a modern, progressive, viable secondary school, the book provides insight into new trends in secondary education. Sensitivity training, organizing for change, constructing a curriculum, scheduling for flexibility, and controlling students and dealing with outside pressures are discussed in relation to the development of a viable school that is capable of constant growth and change while it remains constantly effective and dynamic.
