Based on an institutional-contingency view, this study focuses on ways in which public and private school sectors in six San Francisco area counties embody different organizational logistics and authority principles, including rational-legal, traditional, and local-market. Results suggest that, among other characteristics, nonreligious private schools, following the market model, generate clientele and support by emphasizing distinct educational goals, whereas religious schools, following the traditional model, stress local constituents' commitment. Conversely, rational-legal norms of public schools make social support irrelevant, demand collection and evaluation of standard, aggregated data, and support differentiated decision-making structures which limit constituent involvement. One contrast from previous findings is the suggestion that public and religious schools do not possess different organizational environments. Still, the rational-legal norms of public schools constrain their abilities to generate commitment through means used by traditional and market-oriented systems. Further, an organizing norms-governance practices "fit" is important to members' involvement. The report concludes with recommendations for research and policy options, a one-page bibliography, and two appendixes. (KS)
