This book offers hands-on suggestions for administrators who want to assess their schools' health. The goal is to improve middle schools by making sure the culture is right for all groups--students, teachers, and staff. Chapter 1, "Climate, Culture, and Quality," distinguishes between the concepts of organizational culture and climate, formulates two perspectives of school climate (openness and health) discusses Total Quality Management theory and educational quality, and offers empirical indicators of school quality. Chapter 2, "The Organizational Climate Description Questionnaire for Middle Schools," discusses the conceptual foundations for the Organizational Climate Description Questionnaire Revised for Middle Schools (OCDQ-RM) and explains how to use the instrument. The uses of the "Organizational Health Inventory for Middle Schools" (OHI-M) are detailed in chapter 3. Chapter 4, "Research Findings on School Openness, School Health, and School Quality," presents findings about relationships between organizational climate and quality schools. Steps for using the OCDQ-RM and the OHI-M to assess and change schools are offered in chapter 5. A total of 8 figures and 37 tables are included. The appendix contains sample questionnaires.
