The major purpose of this study was to observe, describe, and explain the decision-making processes and associated leadership behavior of teachers and advisors in secondary schools that individualize their educational programs. Two senior high schools and two middle schools were chosen for observation in this study. A companion study by Dunstan (1981) was conducted simultaneously to analyze and describe decision-making processes and leadership behavior at the school-wide level. The data were gathered by means of qualitative methodology, including interviews, observations and document analysis. Decision-making in the schools was analyzed in terms of decision content, involvement, and process. Leadership behavior of school-wide personnel and of a unit or department were also identified, described, and analyzed. The first chapter includes the introduction to the study, the statement of the problem, and the background and significance of the study. Chapter 2 describes the design and methodology utilized. Chapter 3 includes the presentation of the data. Chapter 4 presents relevant theoretical literature. Chapter 5 analyzes the data, taking into account the literature.
