The centralized secondary center pattern of inter-school district cooperation is examined in this third of four case studies addressing access of rural students to vocational education. The report identifies essential features of this form of cooperation, details factors facilitating/impeding the operation/maintenance of the cooperative arrangement, assesses the program's compatibility with its setting, and recommends modifications for further study and development. Chapter I presents study background, purposes, and methods. Chapter II outlines political, geographical, age, educational, economic, health, social, and agricultural characteristics of the case's south central Minnesota setting. Chapter III analyzes size, facilities, finances, governance, staff, scheduling, curriculum, students, and perceptions of school personnel and community members of the participating school districts. Chapter IV focuses on the history, legal structure, financing and costs, size, staff, scheduling and curriculum, students, and transportation needs of the center. Chapters V through VII detail consumer homemaking, occupational home economics, and vocational agricultural programs. Chapter VIII offers a summary, conclusions, and recommendations. Identified as strengths of the centralized center are its provision for leadership, development, and initiatives regarding the center and its specialized facilities and teaching staff. The most troublesome weaknesses include the necessity for students to travel and the inequalities of access among the school districts. (NEC)
