Research shows teacher influence in school decision-making is related to improving individual job satisfaction and professional commitment. However, few empirical studies investigate how different domains of school decision-making may have a distinct relationship with both individual teacher job satisfaction and professional commitment. Using the Schools and Staffing Survey 2011-2012 and the National Teacher and Principal Survey 2015-2016 which are national samples of U.S. primary and secondary schools, this study examines teacher influence in managerial and instruction domains of school decision-making and whether both are associated with job satisfaction and professional commitment. Results showed that teacher influence in the instruction domain has a statistically stronger relationship with teacher professional commitment than job satisfaction. In contrast, teacher influence in the managerial domain of school decision-making has a statistically stronger relationship with teacher job satisfaction than professional commitment. The results have policy implications for involving teachers in school decision-making and improving their overall job satisfaction.
