Ultimately this has to rest on the experiences of those academics who participate in the process.

It is well known that the standard of applicants applying to each college varies. Therefore all quantitative data is useless until one is able accurately to correct for this differential.



Yes.

These people are just not twisted and cynical enough.

You have a website written largely by the admissions department that finds that admissions are pretty damn efficient and everybody is quoting it like it's an extract from the bible.

The famous "27%" is written in bold on the admissions webpage but nobody explains what it proves. It's just a meaningless percentage until somebody explains it.

OK, chaps, I give in. These are really good numbers. Can someone please explain to me why?

Yes but the question is whether on the balance of probabilities these academics are right or whether they are dishonest or deluded. Whilst I accept the limitations of the evidence, I think that it is more likely than not, that the university picks the best candidates regardless of college selected.

Each College receives a certain number of direct applicants. There are then two success percentages: 1) the percentage getting a place at that college and 2) the percentage getting a place at any college. Measure 1) is influenced by the number direct applicants to that particular college and measure 2) is influenced by the overall number of applications Oxford receives in a particular year.

About 1 in 4 applicants will be successful at current application levels. So measure 2 tends to be close to 25% and does not vary much between colleges owing to reallocation (more on this below). Measure 1 will lie below measure 2 - how far below depends on the number of direct applicants and whether this sample resembles the parent sample (the total universe of applicants).

OK - on to reallocation. There are three main ways in which a candidate may be reallocated corresponding to different stages of selection.

A) Pre-interview, applicants will be banded (usually based on GCSE, A-level predictions, aptitude test scores). The Departments will work with colleges to make sure that the batch each college interviews consists of a range of bands. This is very much in the interest of applicants who don't have to worry about all the other interviewees being highest band while all the other interviewees at another college are lowest band.

B) Post-interview reallocation occurs if more of the candidates retained for interview achieved the standard needed for a place in a particular year than there are quota places.

C) Finally post-A-level reallocation occurs if a student holds an Open Offer that is underwritten by the college they applied to direct. If another student applying for the same course withdraws or misses his/her offer, the Open Offer candidate us taken; if not, he or she may be reallocated to another college where a withdrawal or miss has occurred.

A + B + C adds up to around 1 in 4 students ending up at a college other than the one they applied to direct.


If we are talking about the "college choices" numbers, measure 2 varies between 17% and 27%. To me (and I think this is Nulli's first point) that looks like a lot but I'm not really a statistician.

Can you explain why the really popular colleges (Brasenose, Worcester) have such low import levels if they get a large number of applicants reallocated to them?

Also, someone commented that tutors are not aware which applicants are open. However, the college admissions office must know so are we saying there is a chinese wall within the college?

I don't disagree with your conclusion but for me the question is "Do the stats back up the assertions?" I have never thought that Oxford dons are either dishonest or deluded. A bit odd, perhaps...

It looks to me as though colleges like Brasenose and Worcester can make up balanced interview pools for many subjects mainly from their direct applicants. They have a large number of candidates in each band and so reallocation 'exports' some of these to balance the other pools. In the case of Brasenose, the result is that 244 of their direct applicants secured places at other colleges - almost as many as secured places at Brasenose itself (294). Worcester is a similar story: 319 versus 269.

Yes, that makes sense - except that the colleges must be letting some of the better candidates go to get the balance. Good for the candidates, not so good for the college. Is the reallocation negotiated or imposed?

Look at the 5th column here

http://www.ox.ac.uk/about/facts-and-figures/admissions-statistics/college-success-rates

That column is the total percentage of applying students admitted to Oxford. In a perfect admissions world, that would be good proxy for the quality of applicants to that college. The figures vary between Manchester at 15% and Corpus and New at 25%. That ought to suggest that Manchester has proportionately fewer Oxbridge standard applicants that Corpus and New. So far, so good.

However look at St Hugh's. Again it has a very high proportion of applying students admitted at 23%. That would suggest that it has a very high standard of applicant. However it only exports 16 students which prima facie would suggest a very low standard of applicant.

In reality St Hugh's is only applicable on three bases. Firstly, it has a very high standard of applicant but has upset the other colleges for some reason that other colleges don't want St Hugh's cast-offs. Secondly, it has a low standard of applicant and St Hugh's takes applicants who wouldn't be of the appropriate standard elsewhere. Thirdly, St Hugh's has two constituencies; there is a high proportion of qualified applicants but apart from 16 hand-ons. the rest of the applicants were very poor.

Imposed under the Non-Aggression Pact.

The colleges agreed many years ago that no college would introduce any new admissions arrangements without the support of a majority of the colleges and each college would implement any agreed changes to the admissions system

.A scheme of pre-interview re-allocation was agreed and so each college had to implement it.

Possibly so: the administrative staff might get one set of data, some of which is removed before being passed on to the academic staff. I doubt tutors will bother to hunt for the data even without an actual chinese wall - they're usually occupied with teaching and/ or research, at least from my experience.

I'm not entirely sure re open applicants, but I was re-allocated pre-interview, and my tutor was very surprised when I told her I didn't apply to Brasenose during one of my tutorials subsequently, and claimed that she was unaware of this. Logically, they should be able to deduce who the re-allocated candidates are (for the law faculty, each college can pick up to 2 candidates per place from their own applicant pool, and the remaining interviewees are selected at faculty level before being reallocated randomly), so my conclusion is that 1) my tutor forgot, which isn't unlikely given the sheer number of applicants they look at or 2) they really don't care about where you applied to.

I'd wager a guess that even without a chinese wall, tutors aren't likely to be fussed that someone was an Open or re-allocated applicant. I would like to think that their interest in selecting the best students (whom they will have to teach subsequently) outweighs whatever perceived "affront" they might suffer as a result of being "snubbed" by a student as 2nd choice.

There is a central university admissions department and then the colleges. It is indeed true that the former doesn't let the latter know which candidates are open (or second interviewfor science subjects). They also do things like withhold admissions test scores until after interview to try to make them less biased - there is a well established 'Chinese wall', as you put it.

All applications go through the central university computers before they go to the colleges. If you make an open application, the computer enters a college for you. To the college it looks just as if you chose the college.

nexttime, for most science subjects that can't be true - for one thing the colleges must know whether or not they're providing a room for the candidate. Of course the tutors wouldn't know that. But they typically do the second college interviews the day after they've done first college interviews.

It varies by course. e.g. in Law the colleges only get to hold onto two strong candidates, the rest are liable to be reallocated pre- interview. But I believe that in Maths, the colleges say who they want to be reallocated (i.e. who they don't have enough rooms to accommodate)

Or the Open Application scheme is very efficient, providing St Hugh's with an almost perfect number of suitable students...

(Those statistics include open applications in the college X figures)

Each subject differs. I believe in maths every candidate has a second "choice" college (although the applicant doesn't get to make that choice!), so in a sense everyone is pooled. This of course prevents a college from only letting the no-hopers go, and keeping back all the viable candidates until they have filled all their places and only crumbs are available for those candidates who do not ultimately get in to their first choice. Effectively the first choice college's only right is the right to pre-empt the second choice college.

Open applicants are not pre-sorted. Although the open applicants allocated to St Hugh's may be different in calibre to St Hugh's own applicants, they should, within normal variation, be the same calibre as the open applicants to all other colleges.

The only variation between colleges is the significance of the proportion of open applicants in the total applicant pool to that college.

A college either has a lot of cuckoos or few cuckoos but every cuckoo is the same colour.

Therefore it should not affect what I am saying.

A tutor once told me they even have third/fourth/fifth colleges!

Assuming for now open applicants are of average quality, imagine college X got so few applications that 90% of the applications college X got sent were open applications. Because the candidates they have to consider are of average calibre, they will not need to send many away.

(That's what I was trying to say, although it may have nothing to do with that you were trying to say.)

Actually I would prefer to believe the opposite. I asked for evidence and all people are saying is it must be true because Oxford says so. Can you list out the "absolutely convincing evidence"?


The "absolutely convincing evidence" is publicly available and has already been presented to you. If you refuse to accept this as convincing, there's nothing more anyone can do.

But they typically do the second college interviews the day after they've done first college interviews.


So itake it all science applicants are still interviewed at two colleges as standard. You might be staying with you're choice of college or with the one allocated to you. So whether you're staying with that college or not they still don't know where you've applied. No?

I'm sure they try to do that - it is of course in the interests of everyone involved that admissions are completely fair. However, with it being a human process, it probably isn't perfect (like most things in life).
