I think we can consider the war on single sex spaces in schools to be won, with there being a lot of battles still to fight against the losing side who has not realised they lost. Which means great costs and losses still to come.
Like Nazi Germany at the beginning of 1942, history buffs.
So more battle -
They will be about the specifics of implementation (look up “universal toilets” in the building regs)
It will be about making sure policies are published on websites
It will be about FOIing on the ground implementation policies
it will be FOIing impact assessments and safety positions around these third spaces and the dangers universal toilets will have.
it will be about making sure everyone knows if the budget is blown on universal toilets, how much more expensive that is that the old, safer, cheaper single sex cubicle designs. I think k the cost approach is huge.
Ultimately holding their feet to the fire
And MOST OF ALL pushing to hold those who took these clearly illegal decisions to account and having governing boards remove head teachers and SLT members as often as possible.
