The relationships among Catholic school teachers' commitment, job satisfaction, and work environment are examined. A survey of full-time Catholic elementary school teachers in a large Catholic diocese yielded a 68 percent response rate (n=655). Findings classified three groups of teachers on the basis of three sources of commitment: commitment to faith and organizational values; to the teaching profession itself; and to job-related features. Overall, teachers found intrinsic aspects of their work more satisfying than external factors and expressed general satisfaction. A recommendation is made for conscious administrative efforts to build a faith community and to employ persons whose characteristics match organizational needs. Six statistical tables are included.
