Allows public schools to let certain students not enrolled in school participate in high school interscholastic athletics; allows public high schools in same district to enter into cooperative sports programs under certain conditions.

This bill allows public high schools in the same district to form cooperative sports programs when one school cannot field a varsity team due to low participation or budget constraints. It also permits specific students not enrolled in public school - including those attending nonpublic schools, charter schools, or receiving home instruction - to join their district's athletic teams if their own school doesn't offer that sport and the district cannot field a team. To participate, students must prove residency, meet all athletic eligibility requirements (like academic standards and physical exams), and for home-schooled students, demonstrate equivalent academic progress. Districts may charge participation fees for non-hardship cases but must follow state meal program criteria for financial hardship assessments.
