In this qualitative grounded theory study, 24 participants, referred to as "third culture kids" (or TCKs), ages 18-30 years, who had previously attended international Christian schools were interviewed to determine the dispositions they valued in their teachers. Incorporating principles of grounded theory, a series of rigorous steps were undertaken resulting in the construction of three primary findings TCKs valued in international Christian schoolteachers. These findings were then situated within an extensive literature review. The results provide insight into the "ideal" international Christian schoolteacher desired and valued by TCKs. These findings should be of great interest to anyone responsible for training, preparing or recruiting international Christian schoolteachers, and/or providing ongoing professional development to the teachers in such schools.
