Each academic year, a large number of teachers voluntarily assume coaching positions in Canadian high schools and thus undertake the dual role of teacher-coach. To date, much of the scholarship on teacher-coaches has been conducted with small samples of participants and as such, the conclusions that can be drawn about the status of the Canadian teacher-coach are limited. The purpose of the current study was to profile the Canadian high school teacher-coach using a national sample. A total of 3062 teacher-coaches (males = 2046, 67%) emanating from all Canadian provinces and territories completed a questionnaire examining personal background and work conditions. Results indicated that aspects of teacher-coaches’ personal background significantly influenced the benefits and challenges they perceived from coaching as well as the recommendations they suggested to improve their coaching experience. The recommendations put forth by the teacher-coaches to improve their work conditions must be earnestly considered by school administrators to ensure the long-term viability of the Canadian high school sport system, which is largely sustained by dedicated volunteers.
