I agree that more evidence is neede, because there are surely schools out there who get great results without this very draconian approach (I went to a selective private school and it was no where like as strict as this).
I also think comparing to NI or Scandinavia, which are far more monocultural, is pretty pointless. We know that monocultural societies get better results. We are not a monocultural society in England so what are people suggesting? That we should return to that?
Regarding critical thinking, I have seen in a number of threads people who have colleagues who have gone through Far Eastern schooling who on paper are as bright as can be but have really fallen down when required to think outside the box. Luckily this school doesn’t sound quite that bad.
I read an article a while back about what education systems create the most enquiringly minds and those which regard teachers with very high regard are right up there and that sounds like something this school is getting right.
However, is till do have concerns with how these kids will get on after school. We know that at uni state school kids do better than the spoon-fed private school children. I’m not sure that Michaela children will fall into the first bracket.
