This study investigated how teachers built trusting relationships with their school principals. Study participants were a group of elementary and secondary school principals, associate principals, and assistant principals in southeast Texas. A total of 119 of these administrators completed two Likert-like surveys to identify factors that led them to trust teachers. The two surveys were the Study of Trust and the Survey for How Teachers Create Trusting Relationships with Their Principal. Results of factor analysis indicated that trust was very important to the success of the teacher-administrator relationship. Teachers who cared about students by being sincere, honest, fair, and respectful tended to gain the trust of their principals. Other factors included the ability of teachers to influence their students, to be good teachers, to have a friendly and cheerful disposition, to be loyal and competent, to be good workers, to relate to parents, and to take responsibility for their actions. An appendix contains the two surveys. (Contains 7 tables and 15 references.) (Author/SM)
