Senate Bill No. 388 establishes new eligibility criteria for students enrolled in charter schools or virtual charter schools in Oklahoma to participate in extracurricular activities offered by their resident school districts. According to the bill, these students can only participate if the activity is not available at their charter school and does not have an associated course requirement. The eligibility will be determined based on the rules and policies of the resident school district and any relevant school athletic associations. Additionally, the bill clarifies the definition of "resident school district" and codifies this new section as Section 3-140.1 of Title 70 in the Oklahoma Statutes.

The bill also amends existing laws regarding charter school enrollment and participation in athletic associations. It removes the requirement for charter school students to obtain a transfer to attend a charter school in their district of residence and introduces a new provision that mandates school athletic associations to adopt a written policy allowing charter school students to participate in interscholastic activities. Furthermore, it specifies that statewide virtual charter schools will be considered as having state-wide geographic boundaries and outlines the enrollment process for students whose parents are on active military duty. The act is set to take effect on July 1, 2025, with an emergency clause for immediate implementation upon passage.
