Bubbles - I think at this stage they cant refuse admission. However what they do do is make it very very very clear what they are like at open evening so people can make an "informed choice" as to whether its what they want. I suspect that filters out quite a few.....
Annecdotally theres a bunch of upset parents,especially around mental health issues.
However the other side is that the structure and quiet is good for some kids... and officially if not in lessons they are able to access more support..... FOr some SEND I guess it works well? Not my area of expertise....
And yes to letting parents off the hook - they say that in their open evening - never have to make a paper mache homework with them again! Its nearly all "self-quizzing" and if they dont do it they stay in after school for detention so the parents dont have to worry at all!
I'm fascinated by the school. Instinctively I don't like it at all as it is so far removed from my teaching style and personality as a student. However you cant deny its working/getting results/lots of people love it and its now oversubscribed.
