Antecedents for interrole conflict between the teaching role and coaching role for the high school teacher coach (TC) were examined. It was expected that younger TCs, those in smaller schools, TCs with more coaching jobs, or TCs with an unbalanced role preference will experience more conflict between the teaching and coaching role. Using regression analysis, the results suggest that school size, age, role preference, and number of coaching jobs were significantly related to total interrole conflict. Surprisingly, the relationship between the number of coaching jobs and interrole conflict was negative, when it was hypothesized to be positive. Discussion of the impact of each antecedent is given.
