High school sports enrollment requirements in the United States are designed to ensure fair competition and promote student-athlete welfare. These requirements typically include academic eligibility, age and grade restrictions, and participation in physical education classes. Academic eligibility involves maintaining a minimum GPA or passing a certain number of credits. Age and grade restrictions ensure that students are within the appropriate age range and grade level to participate. Physical education class requirements ensure that students are physically fit and have a basic understanding of sportsmanship.

According to the National Federation of State High School Associations (NFHS), approximately 18 million students participate in high school sports annually. The NFHS reports that 94% of high school athletes meet the academic eligibility requirements, which include maintaining a 2.0 GPA or passing a certain number of credits. Additionally, the majority of students (85%) meet the age and grade restrictions, and 90% have completed a physical education class within the past year. These data indicate that the enrollment requirements are effective in maintaining a level playing field and promoting student-athlete well-being.
