This book examines case studies of eight public and eight private schools that investigated different identifiable and transferable private school practices that public schools could adopt to improve student outcomes. Data came from interviews with administrators, teachers, parents, and students from diverse schools. Chapter 1, "Accountability to Parents," discusses resistance to parents, structural limits to parent accountability, managing participation at parochial schools, lower-income parent participation, cases of formal accountability to parents, and observations about accountability to parents. Chapter 2, "Clarity of Goals and Expectations," discusses the religious character of parochial schools, broader educational goals versus testable outcomes, anchoring expectations in scripture, and clarity of goals. Chapter 3, "Behavioral and Value Objectives," discusses different approaches to discipline and the teaching of ethical and religious values in public and private schools. Chapter 4, "Clear Standards for Teacher Selection and Retention," includes faculty collegiality, hiring standards and teacher quality, formal and informal teacher evaluation, teacher retention and dismissal, and observations on selection and retention. Chapter 5, "Similarity of Curriculum Materials," discusses formal curricular similarities. Chapter 6 discusses "Competitive Improvements." Chapter 7, "Conclusions," suggests that similarities between public and private schools and the problems they face outweigh the differences. Differences are determined mainly by parent socioeconomic and cultural factors. Case study descriptions are appended. (Contains 17 references.) (SM)
