Hi! One of my stories is set in a boarding school, and one of the characters is nonbinary. Since the dorms are split into male or female, I was wondering what dorms this character would be put into? Or if they might get their own dorm (but then which building, male or female, would that dorm be in?). I'm not sure if you'll know this since you aren't boarding school experts, but I thought it might be worth asking.
Unfortunately I cannot really answer this. A boarding school has its own internal structures and standards that vary between each one. I know some schools in reality have created co-ed/nongendered arrangements, but if your character is the only/first nonbinary individual the school has dealt with then it’s rather up in the air.
Best situation would be the school letting the nonbinary character choose where they want to dorm, worst situation would be the school dictating not only where the nonbinary character could sleep, but how they are to present themselves and act.
