My school recently moved into an all new building. There are 5 floors, with an average of two gender neutral bathrooms on each floor. I was allowed to use the faculty restrooms in the old building after girls screamed when I walked into the women's restroom and received looks of disgust from the boys when I went into the men's. However, when I got to the new building, I discovered that all off the gender neutral restrooms were locked and turned into faculty restrooms.
I fought with the principal a bit about how it even says on some of the restrooms "gender neutral restroom available on ___ floor" and yet, when you got there, it was locked, but she came up with many excuses. So, I had to find teachers to open the doors for me. We ended up having a 504 meeting, which was initially for my anxiety, and they made it so I was allowed to use the faculty and nurses restrooms whenever. Unfortunately, this still meant I had to get a key card from teachers and go all the way to the 2nd floor for the nurse's.
Since its my last year at the school, I've decided not to fight much, especially when I tried to get the GSA's support and was told it wasn't a priority problem since I am the only open trans person in the school.
Having a gender neutral bathroom I think should be a requirement in schools. Maybe to avoid the possibility of "makeout sessions," cameras could be pointed at those bathroom entrances. Our school already does it for the normal restrooms.
