This study investigated perceptions about the effectiveness of a student-led sports event. Participants from a student-led tag rugby league were surveyed about its perceived effectiveness. The sample consisted of 227 participants, most of whom were undergraduates (91%) across a wide variety of academic programs. The effectiveness of the league was assessed by comparing the perceptions of participants with previous tag rugby experience with participants who had no previous tag rugby experience. Participants enjoyed participating in and reported above-average levels of commitment to the league. However, there was a difference in perceptions about the effectiveness of the league between men and women. Men with previous tag rugby experience had significantly lower perceptions about the effectiveness of the league than their counterparts with no previous experience. Post hoc analysis revealed the importance of rules and officiating protocols to men. The findings not only speak to the viability of student-led sports events but also to the utility of obtaining direct feedback from event participants themselves, which is a critical aspect of rounding out the post hoc event evaluation process. Results indicate that university course instructors should pay particular attention to knowledge of rules and officiating protocols before selecting students to deliver a league.
