Ontario public school systems are responsible for ensuring that Ministry of Education documents, such as subject guidelines, are implemented in their schools. This paper describes an implementation plan developed and used in Simcoe County by a large rural school board with modest program support staff. Four distinct phases characterize this board's Document Implementation Plan: validation, planning, implementation, and review. Each of these phases is discussed in turn, and some of the inevitable tensions that arise when a local jurisdiction attempts to implement centrally developed provincial curriculum standards are also examined. The sources of tension include provincial direction versus local responsibility, collective agreements, shifting financial responsibility to local municipalities, limited resource materials, the large number of documents that must be implemented, the specified timeline, readiness for implementation, and accountability for curriculum implementation. The report concludes with a number of reflections on the implementation process. (TE)
