They’ve also said that “sexual norms” are protected under the Equal Status Act
Ish. They correctly say that sexual orientation is protected, but then conflate it with "sexual norms" in the next sentence. Clever.
If I were on the board of management of a secondary school, I'd find it pretty easy to argue that my preferred school policies (as a gender critical parent) are consistent this guidance for the most part while still being consistent with safeguarding principles.
School overnight trips, for instance, do not require shared accommodation for girls and male-bodies trans students. Rather, the guidance says that activities should be with the chosen gender. So the male-bodied trans students might sit in the self-esteem development session with the girls rather than the boys, but sleep on their own in a single room. Not perfect as it doesn't take that girls' views into account, but at least it follows basic safeguarding.
PE is the tricky one, and frankly I'd advocate for all PE activities to be mixed sex from now on so that the boys can adapt their playing, in a supervised environment, to a style suitable for mixed teams. If you don't divide PE activities by gender at all, then the guidance doesn't come into play.
