(a) As used in this Code section, the term “athletic association” means any association of schools or any other similar organization which acts as an organizing, sanctioning, scheduling, or rule-making body for interscholastic athletic events in which public schools in this state participate.
(b) No high school which receives funding under this article shall participate in, sponsor, or provide coaching staff for interscholastic sports events which are conducted under the authority of, conducted under the rules of, or scheduled by any athletic association unless the charter, bylaws, or other governing documents of such athletic association provide that a student shall not lose eligibility to participate as a team member on an interscholastic sports team solely because such student participates during the school year at any time outside of regular season, including playoffs, in a national competitive event, such as an all-star or showcase event, that is not sanctioned by such athletic association.
