The problem of this study was to determine what relationships exist between teachers' perceptions of principals' executive professional leadership and teachers' perceptions of principals' behavior in five aspects of administrative behavior. These administrative areas include Principals' support of teachers' authority (EPA), principals' egalitarian relationship with teachers (EPR), principals' involving teachers in decision-making processes for the school (EPI), principals' support of teachers in managerial matters (EPM), and principals' social support. Subjects for the study were grouped according to gender, length of service and level of education for descriptive purposes and to determine variations in their perceptions of the principals' administrative behaviors. Significant relationships were found to exist between teachers' perceptions of principals' EPL and EPI leadership and teachers' perceptions of principals willingness to involve them in decision—making processes for the schools (EPI). A significant negative relationship was also found to exist between the teachers' perceptions of principals' leadership (EPL) and teachers' perceptions of the managerial support (EPM) provided by principals. A slight negative relationship was found between teachers' perceptions of principals' leadership (EPL) and teachers' perceptions of social support (EPS) received from principals. There was a slight but insignificant positive relationship between teachers' perceptions of principals' executive professional leadership (EPL) and teachers' perceptions of egalitarian relationships (EPR) which existed between the teachers and principals. A positive but not significant relationship was also noted between teachers' perceptions of principals' leadership (EPL) and teachers* perceptions of the manner in which principals granted them professional authority (EPA). When teachers were grouped by demographic variables, two important trends in^perceptions were noted regarding principals' executive professional leadership. (a) Female teachers had a tendency to perceive principals as having lower professional leadership than did male teachers. (b) Teachers with higher educational levels perceived principals as having less professional leadership ability than teachers with relatively low educational levels. Teachers' level of experience did not appear to have any systematic significant impact on their perceptions of the principals' executive professional leadership. It was recommended that those who train principals should be aware of the need to emphasize professional administrative areas which are critical to teachers' perceptions of leadership in the schools because teachers' perceptions affect their teaching performance.
