Teachers should possess a set of professional commitments, which includes active participation in professional development that leads to student learning. The purpose of this study was to explore the relationship between professional development engagement and career satisfaction. This study used a quantitative descriptive correlational research design. A purposive stratified sample of states and a census of teachers in those states were used. The Tailored-Design Method, using multiple points of contact with various modes was used to collect data with minimal survey error. There was a response rate of 72.5% (n = 892). The mean score for the professional development engagement was 118.3 (SD = 13.4; n = 858) on a 150 point scale. Agriscience teachers participated in workshops at a higher rate than any other type of professional development. Levels of implementation varied among types of professional development. The mean score for career satisfaction was 19.9 (SD = 4.4; n = 878) on a 25 point scale. Professional development engagement and career satisfaction had a moderate positive correlation (r = 0.34). These findings showed a high level of participation in professional development, especially workshops and a high level of career satisfaction. Recommendations for practice and future inquiry are provided.
