Students in Arkansas public schools and charter schools must use bathrooms matching their biological sex under a new bill recently signed into law by Gov. Sarah Huckabee Sanders.

The law applies to communal restrooms and locker rooms for students in pre-K through 12th grade (pdf).

“The governor has said she will sign laws that focus on protecting and educating our kids, not indoctrinating them and believes our schools are no place for the radical left’s woke agenda,” Alexa Henning, a spokesperson for Sanders, told Reuters. “Arkansas isn’t going to rewrite the rules of biology just to please a handful of far-left advocates.”

Sex is defined in the bill as the “physical condition of being male or female based on genetics and physiology.”

Schools are directed to rely on a student’s sex as identified on his or her original birth certificate.

Schools are additionally required to “provide reasonable accommodation to an individual who is unwilling or unable to use a multiple occupancy restroom or changing area designated for the individual’s sex,” such as single-occupancy bathrooms and changing rooms.

A reasonable accommodation doesn’t include access to a restroom or changing area designated for use by members of the opposite sex while the members of the opposite sex are present.

The law doesn’t apply to an individual who enters an opposite sex area for custodial, maintenance, or inspection purposes, or someone who is providing emergency medical assistance or responding to an ongoing emergency, including a physical altercation.

The bill does not prohibit schools from adopting policies to accommodate individuals protected under the Americans with Disabilities Act or young children in need of physical assistance when using such facilities.

The bill also applies to overnight trips sponsored by the school district.

During overnight trips, schools must ensure students only share sleeping quarters with a member or members of the same sex or provide them with single-occupancy sleeping quarters.

There’s an exception for opposite-sex students who are in the same immediate family.

Any allegation of noncompliance with the bill should be referred to the Professional Licensure Standards Board by filing a formal complaint.

School authorities in violation of the law are subject to fines of at least $1,000. The law also allows parents to file lawsuits to ensure the law is enforced. Additional sanctions can be levied against the school district’s superintendent, school principals, directors, or teachers if they are found to specifically be in violation of the law.

The bill’s sponsor in the House, Republican state Rep. Mary Bentley, told the Senate Education Committee in March that the idea for the bill came after several members of a local school board approved a similar policy in October, the Arkansas Democrat Gazette reported.

Donn Mixon, an attorney representing roughly 45 districts in the state, told the Arkansas Democrat Gazette that some districts have allowed students to use the restrooms in which they feel most comfortable, and they will have to change their policies.

Other districts have already been following policies in line with the new law.
