In every public school setting in which a student may be in a state of undress in the presence of other students, school personnel shall provide separate, distinct areas designated for use by students based on their biological sex to ensure the personal privacy and safety of students.

Every public school shower room, locker room, and restroom designated for student use and which is accessible by multiple students at the same time shall be designated for and used only by students of the same biological sex. At no time shall a student be allowed to access a public school shower room, locker room, or restroom designated for use by the opposite biological sex.

A student who asserts to school officials that his or her gender is different from his or her biological sex may be provided with alternative shower room, locker room, or restroom accommodations, provided that a parent or legal guardian of a minor child who makes such assertion shall provide written consent to use of such alternative accommodations. Such accommodations shall not include the use of student shower rooms, locker rooms, or restrooms designated for use by students of the opposite biological sex.
