@fivecandles: Thank you for taking a different tone in this discussion. Please understand that I am not trying to bash teachers. My questions and comments have always addressed the end result (11 students applied to Oxbridge and ten were offered places) and I believe I am keeping an open mind as to why the results are what they are. Please note also that I regard the result as belonging to both the school and the students. I have not implied that teachers are primarily responsible for these results; I have repeated indicated my agreement that the students are principally responsible and that they make their decisions based on inputs from sources as well as their teachers.
For me, Oxbridge acceptance is a proxy for achievement. You apparently believe similarly as you seem quite proud of your school's results. But I believe we agree that it is only a proxy and there are many other results that indicate as high an achievement.
I'm guessing that ten out of 11 may be a better result than your long-term average and may be better than your Oxbridge coordinator expected. Please note that I am not trying to insult your school or denigrate the result. I am merely commenting that I find this result quite extraordinary. If this result is consistent with previous years' results and with your school's expectations, just say so and I will be even more impressed.
But, even if ten out of 11 was a better than average year, your program clearly did an excellent job with the students who chose to apply to Oxbridge. I assume that it did an equal job with those who preferred to apply to, for example, Medicine & Dentistry at non-Oxbridge schools, or top fine arts or performing arts courses, etc.
I do believe university acceptances are probabilistic and noisy, definitely at US universities, more so at most UK universities and even more so at Oxbridge. The reason I believe that is that, in the US, you generally apply to a entire university, not just a course. Over there, variability in admissions can arise from things such as fluctuations in the quality of the applicant pool from year to year, fluctuations in the relative weighting the admissions office gives to various criteria and, just possibly, whether the admissions officer reviewing your application is having a particularly good or bad day. But at Harvard, you are competing for one of 1600 places regardless of which year you apply and you have a pretty good idea of how many other students are applying.
My understanding is that in the non-Oxbridge UK schools you apply to a specific course. Any given course may have more or fewer places in a given year and more or fewer applicants. So a student who might be offered a place one year might not be offered one the next year. My understanding is that it gets even more variable at Oxbridge because you apply to a course within a college, and that most college/course combinations are quite small, admitting just a handful of students each year, so that a student who might be offered one of six places one year might not be offered one of three the next year. Add to that the variability in the quality of the applicant pool to each college/course combination (perhaps this year an exceptionally large and talented group of people apply to Law at XYZ while an unusually small and unexceptionally qualified people apply to Economics at ABC) and you've got a probabilistic outcome. And applicants can have particularly good or bad days at their interviews; I'm guessing that interviewers cannot always see through that, so there is another source of variability.
Now let's be clear on what I have been asking: Outside of the 11 who applied, are there any students at your school who would have gone to Oxbridge had they been offered places? Please note that, for the purposes of what I really want to know, you could extend it to Medicine & Dentistry programs anywhere, top fine arts or performing arts courses, etc., or just generally "better" courses than those to which the students actually applied.
But getting back to Oxbridge, you wrote earlier that you believed at least some students did not apply to Oxbridge because "[they decided] that given their chances of getting in are slim they could do without the stress" I interpret this statement to indicate that, yes, some students at your school would have preferred to attend Oxbridge had they been offered a place but chose not to apply because they felt the probability of their being accepted was so low as to make it not worthwhile.
Is it not possible that some of these students underestimated their chances of getting into Oxbridge (or Medicine & Dentistry, etc.) Whether it is because of how your school selects students or in the way you teach students, your better students appear to have a much higher than average chance of getting an Oxbridge place. Do you think they fully understand that? Put it another way, after seeing the success rate of their peers who did apply to Oxbridge, do you think some of the other students might wish they'd "given it a go"?
You have declined to say how many students your school enrolls overall. This matters because, if your school teaches only 20 kids a year then I can very well believe that the other nine all found equally fulfilling alternatives and none of them would have gone to Oxbridge even if they'd been offered places on a silver platter. If your school teaches 200 kids a year then I'd find that harder to believe.
Believe me, in my line of work I understand selection bias. Those of your students who self-selected to apply to challenging courses were already, on average, the better performers and higher probability candidates. But I also understand that most real world distributions are continuous, not step functions. My guess is that your first cohort of 11 did better than you or they, the students, expected, and that, conditional on your first cohort having done so well, your second cohort would also have done better than you (or they) expected. But no one will ever know, since they did not apply.
Hopefully you realize that I did not really believe you were patronizing when you suggested that your straight A student might be capable of more things than hairdressing and would probably be better off going to university. Perhaps I should have included a warning about American sarcasm in the last sentence of my previous post.
I happen to think the following would be good things:
- If state school students understood the "true" probability of gaining Oxbridge (or other challenging) places. It's not easy, but it's not impossible.
- If state school students understood the expected rewards of a challenging degree. This thread began, after all, as "Who gets the best jobs?". In addition to the financial considerations, people with "better" degrees tend to have more flexibility and options.
- If students' parents, peers and other influences understood the benefits of doing challenging degrees.
I suspect you desperately tried to ensure at least the first two with your former pupil turned hairdresser. Something I'd like to understand more about is the difference in the third between the US and the UK.
