The purpose of this study was to determine the primary school principals' views on trust in students and parents and also, to explore the relationships between principals' levels of professional burnout and their trust in students and parents. To this end, Principal Trust Survey and Friedman Principal Burnout scales were administered on 119 primary school principals (F = 7, M = 112) working in Malatya, a city located in the eastern part of Turkey. Research results revealed that principals' views on trust in students differ significantly in terms of school size. It was revealed that principals working in small schools get the lowest scores from "burnout" scale, while principals working in big schools get the highest. It was also found that, contrary to the burnout, principals working in small schools get the highest scores from "trust in students" subscale, while principals working in big schools get the lowest. Results also showed that principal trust in parents and students variables altogether account for approximately 21% of the total variance in exhaustion, 22 % of the total variance in depersonalization, and 6% of the total variance in accomplishment.
