Looking at the school's own website ot is interesting that all the photos show only female pupils but all the language is bery carefully gender-neutral.
Earlier this year, I attended a leavers ceremony for a girl’s school. And every mention of the word ‘girl’ by speakers was noted with an obvious shared glance of disdain between two teachers wearing rainbow lanyards.
It was not subtle and was noticed by others, not just me, including some of the girls at the ceremony.
