I think it depends on how and why the curricula is chosen.
I went to a girls' school and for O Level we studied 'Lord of the flies', not a single female character in it.
If it is a question of giving the group a list of texts and letting the students choose that is different to the ones highlighted by a previous poster.
Also for PE, if students vote on which sports / dance / movement classes then that's fine, if they are told girls do dance, boys do football that's different.
Not having adequate safeguarding though on its own deserves an inadequate rating. Children need to be safe in order to learn.
