Which associations are schools with intercollegiate sports commonly affiliated with?

Schools with intercollegiate sports are predominantly affiliated with the National Collegiate Athletic Association (NCAA). The NCAA is the primary governing body for college athletics in the United States, overseeing the rules and regulations that govern intercollegiate competition, athlete eligibility, and championship events. Founded in 1906, the NCAA has developed a comprehensive framework to ensure fair play and maintain the integrity of college sports, making it the largest and most recognized authority in this area.

This affiliation provides student-athletes with opportunities to compete at a collegiate level, promoting their development in both athletics and academics. While other associations mentioned may focus on various aspects of sports or younger age groups, they do not hold the same level of prominence or governance in the context of intercollegiate athletics as the NCAA.
