It is a premise of this Association for Supervision and Curriculum Development (ASCD) yearbook, that staff development will become a human Curriculum Development (ASCD) yearbook, that staff development will become a human resource development system designed to change the nature of schooling, the status of its personnel, and their relations with each other. The structure of staff development is the volume's main focus. Part I deals with the research base as it bears on the design of culture-oriented staff development programs. Part II deals with the principalship, school structure, district personnel relations, staff development organization, and the university and its relationship to the schools. Part III describes current developments in Australia, England, and Wales. Part IV describes staff development intitiatives in two very large school systems (Pittsburgh, Pennsylvania, and Los Angeles, California) and two medium-sized districts (Lincoln, Nebraska, and Anchorage, Alaska). Each of these programs was chosen because each can significantly affect the workplace itself as well as deliver services. An epilogue discusses the "curious complexities of cultural change." The ASCD Board of Directors and other staff are listed. Each chapter includes a list of references. (MLH)
