The "Questionnaire for the Assessment of Enjoyment in Physical Education" (QUAEPE) is an instrument for the assessment of three specific facets (pleasure, flow, recovery) of students' enjoyment in physical education. Based on a sample of 1,351 students, the aim of the present study was to examine measurement invariance across school tracks and relationships with students' grades in physical education. Support for strict measurement invariance across school tracks was found. The three facets of enjoyment correlated highest with grades in physical education for students attaining school in the lowest ability track and lowest for students in the highest ability track. These results suggest that there may be distinct classroom practices in physical education for different school tracks, which have an impact on the relationship between performance and affect.
