Unless you go to church, your choices are very limited. She left the school 6 years ago after GCSEs and it’s only in the last couple of years of Uni and starting to work that she has regained some confidence and has less anxiety
I recognise this. Unless you are Catholic, or rich enough to go private, or have some kind of pull somewhere, there's not much choice at all in the area. We put HP on the list because it was literally the only non-Catholic state secondary school within any sort of plausible catchment area.
As for the head leaving - that shouldn't let him off the hook. He's an absolute disgrace.
And the top members of the "leadership" team - a bunch of out-of-control bully boys in Hall's image, for the most part - are culpable as well. Chappell and Wilson are the Crabbe and Goyle to Hall's Draco. (Except at least Draco was redeemable.)
Hall needs investigating, prosecuting if necessary, and a very close look at his assets. He shouldn't go out with a party and a gong.
