HelloItsMeFell, my observation from mingling among parents, and using my ears as well as my eyes, was that the proportion of white-british families sitting the test was a lot lower than the 30% that makes up the school poulation. My instinct is to wonder why. There could be a number of reasons, or combination of reasons, some of which have been suggested here.
If I was a social science academic looking for a project, I'd be investigating. I would want to interview applicants and their parents about their motivations, and the preparation process, and see if there were trends in families from different backgrounds. However, as I'm a busy working mum I guess I'll have to hope someone else picks it up instead.
"If there are only 150 places at the school in question and 1700 dc sitting the test - 70% of whom are non-white British then the excessively competitive tutoring culture is obviously being driven up by the fierce competition WITHIN the non-white ethnic groups, ie competition against each other!"
Yes, Clavinova, that's what I'm thinking too. I suspect it's not least to do with the fact that many of the faith-school options aren't available to them, so their access to that elusive thing called "choice" is very limited.
RabbitStew: "I think you will find a fair proportion of the parents of children from White, British backgrounds are accessing tutoring to help their children get into the school"
Yes, but the ones I know just tutor once a week for a year in VR/NVR. They don't tutor "for years". Also, about 50% of the ones I know who have been offered a place have chosen other (private) schools instead, because for various reasons they have felt this school wasn't the right choice for their boys.
