This study sought to analyze and compare administrative organizations and operational patterns of 18 Michigan junior colleges functioning in 1964-65. The factors were examined historically; by concept and theory; by type, structure, and function; and by changing concepts and trends. A questionnaire solicited data on existing organization structures, on operational patterns, and on the relationship between the two. It also collected information on the operative factors in the structures and patterns by means of charts, lists of duties, and lists of committees and their functions. From these data, the investigator devised an organization chart to serve as a guide for reorganizing existing and establishing new junior colleges in the state. His accompanying recommendations were that (1) the Michigan Council of Community College Administrators formulate guidelines for titles and duties of administrators; (2) job specifications be set up to prevent overlapping of duties and to prevent an administrator in one area from functioning in another; (3) administrative theory be extensively applied in organizing and reorganizing administrative structures; and (4) the Michigan Association of Junior Colleges undertake a program to involve more faculty in decision-making processes.
