Organizational development (OD) can be of value as a professional development tool in the school, especially where it can broaden the perspective of the teacher so that he can conceptualize the school as an organization with various related units working to achieve the same goal, see more clearly his place in the total educational program of the school, and see his place in the total school organization. This increase in the interdependence of teachers will be of real value as schools try to implement changes, such as school-based budgeting, team teaching, and the total curriculum, that involve the total school organization and as state departments of education try to decentralize some decision-making to the schools. Inservice programs on OD in Manitoba are described. (Author/IRT)
