The results relating to staff development, contained in a Rand Corporation survey on change agents, are summarized in this paper. The researchers discovered that successful staff development program implementation was characterized by three major components: local materials development, online planning, and concrete, ongoing training. Their research indicated two basic types of staff development models--the deficit model and the "developmental strategy" model. The developmental strategy model involves teachers and principals in preparing for change and is not standardized. The school district offers consistent financial support and relies on local resource people to guide innovative efforts whenever possible. The researchers conclude that effective staff development depends much more on the district's point of view about principals and teachers as learners than on the specifics of the staff development program.
