The purpose of the present study was to explore the contribution of extracurricular coaching on high school teachers' job satisfaction. Specifically, the study looked at how perceptions of the coaching environment (athlete relationships, colleague relationships and opportunities through coaching) influenced teachers' perceptions of stressors (athlete-related and workload-related) and coaching efficacy, and how this in-turn influenced teachers' job satisfaction. The sample examined 2949 teachers from across Canada who volunteered as high school sport coaches, above and beyond their regular teaching load. The results supported that the data fit the model well (SB[subscript ? superscript 2][subscript 264]) = 973.36, p < 0.001, SRMR = 0.08, CFI = 0.91, TLI = 0.90, RMSEA = 0.055 CI[subscript 95][0.052, 0.059]) and that teachers who reported a positive coaching environment had increased coaching efficacy and decreased perceptions of athlete-related and workload-related stressors. Increased coaching efficacy predicted higher job satisfaction, while increased perceptions of stressors predicted lower job satisfaction.
