Academic eligibility policies are rules that are put in place to ensure that students maintain a certain level of academic performance in order to participate in extracurricular activities such as sports, clubs, and other activities. Research has been conducted to determine the effectiveness of academic eligibility policies in secondary school environments. Here are some studies and references on this topic:

Overall, the research suggests that academic eligibility policies can have a positive impact on student academic achievement and participation in extracurricular activities. However, it is important to note that academic eligibility policies should be implemented in a way that is fair and equitable for all students.
