Extracurricular activity participation has been associated with a multitude of positive outcomes, including school completion, and research suggests that students at risk for school failure are particularly likely to benefit from participation. However, before extracurricular activity participation can be promoted to address such issues, predictors of participation should be examined. Thus, the purpose of this study was to examine the school-based extracurricular activity participation characteristics of middle school students, with an emphasis on that of Hispanic students. Hispanic students were less likely than European American students to participate in sports-related activities during the seventh grade. Additionally, within the Hispanic group, females and participants with a bilingual education background also reported lower participation. Results suggest that discrepancies in extracurricular activity participation rates for Hispanic students appear early, and they also underscore the significance of examining participation variability within this group.
