ATHLETICS: Prohibits schools from being members of, or participating in competition sponsored by, any intrastate interscholastic extracurricular athletic association or organization that does not provide for certain student eligibility procedures

HB 644 prohibits Louisiana public and nonpublic schools receiving state funds from joining or competing through any intrastate athletic association that doesn't follow specific student eligibility rules. It directly affects all Louisiana high schools (grades 7-12) that receive state funding and their athletic associations. The bill requires associations to ensure new students are immediately eligible upon enrollment and allows transfers to a student's "home school" (based on attendance zone) without delay, or to other member schools once before 11th grade with time limits. Schools violating this would be barred from participating in competitions sponsored by non-compliant associations.
