(A) Notwithstanding any athlete transfer rules and policies adopted by the interscholastic athletic association, body, or entity, a student who attends a school outside of his attendance zone may immediately participate in interscholastic competitions if the student is otherwise academically eligible and the following conditions are met: (1) for students enrolled in middle school, the interscholastic athletic association shall allow a one-time transfer after eligibility is established in the seventh grade; and (2) for students enrolled in high school, the interscholastic athletic association shall allow a one-time transfer after eligibility is established in the ninth grade. (B) This section does not apply if the student transfers because of a bona fide residency change and a student may not participate in any interscholastic competitions or practices of a school until he is registered in the school.
