This paper describes the first phase of a study of teachers and school administrators in Western Sydney, Australia. A survey to measure teacher satisfaction, motivation, and health was designed based on findings from earlier research. Participants were 529 teachers and school administrators at 47 primary, secondary, and special purpose schools. Major satisfiers were found to be rewards intrinsic to the task of teaching. Major dissatisfiers were found to be mainly matters interfering with teacher and administrator effectiveness. Control was found to be a key issue, in that matters outside teacher and school control caused the greatest dissatisfaction, particularly imposed educational responsibilities and change, and societal expectations and criticisms. Position held was found to predict satisfaction, change in satisfaction, and to an extent, mental distress. Those with the lowest levels of satisfaction, the greatest decline in satisfaction since beginning teaching, and the highest levels of mental stress, were found in middle management positions in schools. Contrary to previous research on job satisfaction, increased age did not predict greater satisfaction. Higher current dissatisfaction and greater decline in satisfaction were both predicted by length of service at current school. (Contains 18 references.) (Author/JLS)
