Ineffective professional development is a longstanding problem in education. Locally, the school district in the study lacked a comprehensive system for evaluating their secondary level professional development programs. The purpose of this case study was to investigate the district's professional development program, specifically examining its perceived strengths and weaknesses. The conceptual framework of the study was systems theory and the adaptive schools reform model. The research questions examined the perceptions of various school personnel on their experiences with the current professional development program at the study district's high school. Individual interviews were conducted with a purposeful sample of 3 teachers, 4 teacher-facilitators, 1 professional development committee member, and 1 school administrator. Interview data were concurrently analyzed using inductive analysis and typologies derived from the literature. The results were used to create a project consisting of a comprehensive policy proposal that provides detailed guidance and procedures for every stage of the school's professional development program cycle. The study project was designed to assist educators, administrators, and school districts in conceptualizing, designing, and implementing professional development programs that are tailored to meet the needs of local educators. This study promotes positive social change through facilitating the development of improved professional development programs that increase teacher quality and student achievement.
