This article examines the relationship between Catholic school teachers' motivation and job satisfaction. The data are derived from a survey of 716 teachers in Catholic elementary and secondary schools in three dioceses in the US (Atlanta, GA; Biloxi, MS; and Cheyenne, WY). The school's academic philosophy and its environment were important predictors of the teachers' satisfaction with their work with students and with their relationships with administrators and other teachers. The motivation to teach in the school because it was a Catholic school was an important predictor of the teachers' satisfaction with the school. The results of the study confirm the importance of a religious factor as an important motivator for teachers choosing to teach in Catholic schools and an important predictor of their job satisfaction.
