I am not fine with a school stating criteria upon which they are grading students who come for “interviews”.
But why not caulifower?
I hear what you say about it being illegal (I haven't checked, but assume that is the case). But taking a step back, is it good for state school students that is is illegal?
if it was similarly illegal (or not done), to interview students for university (as it was in my country when I went to university, where admission was based solely on a score made of adding your four best subjects out of 100 and 10% of any other subjects you took), then I can understand it not making sense to interview for sixth form.
But in a country where it seems from what I am hearing, pretty much all the top university places go to kids on a combination of grades and interview (and sometimes additional exams such as STEP), making it illegal for state schools to put state school students through the exact kind of test, ie an interview, that they will need for university, while the private schools are free to do so and to select on that basis, seems like a legistative attempt to tilt the playing field in the favour of the private schools. And then they wonder why there are so many more kids from private schools in Oxbridge. Here is on reason straight away.
Interestingly enough, when I went to university in my country, there was a lot of criticism of the fact that there were no interviews, particularly for subjects like medicine, with the argument being that it let in the rigidly academic over those who might have a good bedside manner, with the counter argument being that it was so expensive to interview, rather than just ranking everybody's scores and going down the list of applicants and cutting at the point at which you had enough to fill the places (which is also why in my country the final exam results came out and then the universities were able to make offers immediately to the top applicants, so there was no need to make conditional offers). This was regarded as much better than having to make conditional offers, but it did priviledge the kids who were good at written exams over those with social skills, and meant that the first interview most of us had was for a graduate job!
