No public school shall require any student athlete on a single-sex sports team to participate in a match, or any part thereof, against an opposing team that includes one or more athletes of the opposite sex.

The Department of Elementary and Secondary Education, the Massachusetts Interscholastic Athletic Association, or any equivalent school organization or an entity or board that provides athletic officials, including, but not limited to, referees and umpires, for school sports or athletic events shall not penalize any public school, single-sex public school sports team, coach of such a team, or student athlete on such a team, for forfeiting or refusing to play in a match against an opposing team because such opposing team includes one or more athletes of the opposite sex, except that such a forfeit may be recorded as a loss.
