The problem of this study was to determine teachers' perceptions of their school organizational climate, to determine teachers' perceptions of their principal's leadership behavior, and to ascertain the relationships between teachers' perceptions of school organizational climate and principal's leadership behavior. The study had three major purposes. The first was to determine teachers' perceptions of their school organizational climate as measured by the Organizational Climate Description Questionnaire (OCDQ) across selected variables. The second was to determine teachers' perceptions of their principal's leadership behavior as measured by the Leader Behavior Description Questionnaire (LBDQ) across selected variables. The third was to ascertain whether significant relationships existed between teachers' perceptions of school organizational climate and their principal's leadership behavior. Based on the analyses of data, the conclusions could be drawn that: 1. The school organizational climates as perceived by secondary school teachers tended to fall into the closed end of the open-closed climate continuum. It is interesting to note that teachers with more years of teaching experience perceived their school organizational climates as being open. 2. All of the teachers in this study perceived their principal as an effective leader. 3. There was a significant relationship between organizational climate and principal's leadership behavior; however, no matter how teachers perceived their school organizational climate, they still perceived their principal as an effective leader.
