A supportive school environment is crucial to the enhancement of student teaching experiences. This study assesses student teachers' perceptions of secondary school environments, and then relates the perceptions to their satisfaction with school experiences and teaching commitment. The results show that considerable disparities between student teachers' perceptions of actual and preferred school environments and suggest certain directions for improvement. Student teachers' perceptions about their school environments, especially in the areas of professional interest and staff freedom, were positively associated with their satisfaction. Several school environmental aspects influenced the total years they planned to teach and their intention to teach at the placement schools. (Contains 1 figure and 7 tables.)
