Data were obtained from a sample of 263 teachers working in both types of schools, and the hypotheses were tested using hierarchical multiple regression analysis. Results supported all three research hypotheses, showing that (a) burnout level is higher in extremely demanding schools in comparison to normally demanding schools; (b) school principals' level of transformational leadership negatively affects the level of teachers' burnout; (c) this effect is moderated by school type (extremely- vs. normally demanding), such that transformational leadership is more effective in reducing burnout in less demanding schools rather than in high demanding schools. The finding shed light on contextual contingencies of the transformational leadership-burnout relationship.
