Something called the “hatch” amendment. Basically a note given to the school at the beginning of the year that says your child will not participate in anything with same sex or sexually oriented content. look it up online...it’s a bit more detailed but along those lines.
Actually, it was a notice specifically for FLE. It listed times that parents could look over the curriculum and it specifically listed the sensitive items. It then gives several choices of sending them to all, none, or part. We chose none. The school sends the notice out every year to every student and it is specific to each grade
