Correspondence, survey, and group interview data were combined to investigate the nature and consequences of participatory evaluation activities in a medium-sized school district (48,000 students) in Simcoe County in Ontario (Canada). The study focused on the dynamics, supporting conditions, and consequences of internally conducted participatory evaluation. Data were collected from staff who participated in several evaluation studies, including evaluations of student guidance services, library services, intermediate mathematics, intermediate history and contemporary studies, and French as a second language. In each case, the author, as the sole district staff member in a research capacity, provided technical support for problem formation, instrument development, data processing, analysis and interpretation, development of suggested courses of action, and assistance in report writing. Results inform the researchers' understanding of the conditions supporting effective internal participatory evaluation. (Author/SLD)
