Senate committee substitute to the 1st edition makes the following changes.

Deletes proposed sub-subdivision to GS 115C-12(23) that would bar students of the female sex from athletic teams or sports designated for males. Deletes requirement that sports designated for women not have members of the male sex, so that the provision only requires that athletic teams designated for women not have members of the mail sex.  Amends the retaliation provisions to delete athletic association and instead refer to administering organization (i.e., a nonprofit organization that has entered into and is in compliance with a memorandum of understanding with the State Board of Education to administer and enforce the adopted rules and requirements of Article 29e of GS Chapter 115C) for interscholastic athletic activities at the high school level. Changes causes of action for which there are specified statutory remedies from a cause of action pursuant to sub-subdivisions e through h to a cause of action pursuant to sub-subdivisions f through h.

Enacts GS 115C-548.1 (private church or religious schools) to require these schools that are members of an organization that administers interscholastic athletic activities pursuant to Article 29E, and any other of these schools that organize athletic teams at the middle and high school level that plays a team from any school required to comply with GS 115C-12(23), to comply with GS 115C-12(23), as amended.
