Participation in school-based extracurricular activities influences educational success. Thus, it is important to depict a profile of school-based extracurricular activity involvement for a Latino student population that is marginalized in schools. This research uses the Educational Longitudinal Study of 2002 and logistic regression analyses to present a profile of the factors linked to participation in school-based extracurricular activities among Latino 10th-grade students. Results indicate that geographic characteristics, as well as immigration-related characteristics such as immigrant generational status and English proficiency, are pertinent factors in Latinos' participation in school-based extracurricular activities.
