Tennessee Governor Bill Lee has signed a bill requiring schools districts to alert parents of any instruction on sexual orientation or gender identity and let them opt their students out.

Senate Bill 1229 will give parents and guardians the ability to excuse their child from curriculum regarding sexual orientation or gender identity. The bill will prohibit schools from penalizing a student for opting out of the curriculum.

According to the legislation, parents or guardians must be notified of the curriculum at least 30 days in advance. Parents must submit a written request to the student’s teacher, school counselor or principal in order to excuse their child from the curriculum.
