Enrollment decline places new pressures on school administrators and school boards, but Ontario's Commission on Declining Enrollments found no call for a complete reorganization of either the provincial governance system or the structure of the delivery system at the administrative level. This document describes those aspects of Ontario's school system that affect its response to enrollment decline, and cites both constraints faced by school boards facing decline (demographic factors, community and school employee reactions to school closure, and financial factors) and alternative techniques for coping with decline (staff reduction, reassignment, or reorganization; school board restructuring; and allocation of surplus space). Areas listed as requiring attention at the provincial government level include support for minimal programs, long-range financial planning, appropriateness of school district boundaries, fixed costs, improvement in provincial-local relationships, and in general the assumption of a leadership role in education. Information on specific local situations was gathered in a survey of 11 of Ontario's 194 school boards. (Author/PGD)
