This investigation explored what hinders and contributes to the level of trust a teacher has of the principal. Two research questions guided the investigation concerning what specific incidents teachers felt affected trust with the principal. This case study allowed veteran elementary teachers to be interviewed and share personal incidents that they felt influenced the level of trust they had with their principal. Teacher participants shared a wide variety of incidents that included both their personal and professional lives. Teachers most often identified incidents where the principal showed benevolence, openness, and honesty. The results of this study led the researcher to infer that teachers have a higher level of trust with principals that show care, communicate openly, and connect with them on a personal level. This study provides implications for the preparation and professional development for K-12 principals. [The dissertation citations contained here are published with the permission of ProQuest LLC.
