Guided by the trichotomous achievement goal framework, the current study examined mastery, performance-approach, and performance-avoidance goals and their relations to self-reported persistence/effort among Turkish students in secondary physical education. Two hundred twenty-nine students in grades 8 and 11 completed questionnaires assessing their achievement goals and self-reported persistence/effort in secondary physical education. Results of this study revealed that 8th-graders scored significantly higher than 11th-graders on performance-approach goals and self-reported persistence/effort. Mastery goals and performance-approach goals emerged as significant positive predictors of students self-reported persistence/effort, but their predictive power varied by grade. Overall, results of this study provide empirical support for the trichotomous achievement goal framework in the context of secondary school physical education.
