here you go summer all England breakdown. Cohort success rate:
45% to 50% 1 school, 45.2%
35% to 40% 2 schools, both Indies, avg 36.9%
30% to 35%, 5 schools, all indies, avg 32.6%
25% to 30%, 5 schools, all indies , avg 27.3%
20% to 25%, 5 schools, all indies, avg 21.0%
15% to 20%, 22 schools, 16 indies & 6 state, avg 17.3%
10% to 15%, 51 schools, 37 indies & 14 state, avg 12.0%
5% to 10%, 137 schools, 89 indies & 48 state, avg 6.9%
0.1% to 5%, 1533 schools, 271 indies & 1262 state, avg 1.2%
0% (eg no successful applications), 233 schools, 38 indies & 195 state
In truth the final 0% will be higher and the 0.1 to 5% lower as Cambridge, unlike Oxford, do not specify the actual number of applications and accepts, where an individual school has less than 3 candidates in one or other category. Obviously an average per school can be worked out, but it means there will be some schools counted in for Cambridge who in reality received no offers. Just to put that in context we're talking almost 1000 schools with less than 3 applications to Cambridge.
The 394 schools from Scotland, Wales, NI. Channel islands with applications are not included as the DoE does not report any info on them - something about devolved government :). Between them they managed around 230 offers, and there are only a handful of schools who might have crept towards the 5% cohort success rate.
78 English schools I could not reconcile with the DoE data (they have a few postcode data quality issues). However again these schools in total had 24 offers fairly evenly spread so cohort figs likely to be low (only 1 school with more than 1 successful applicant).
It is just the 2013 cycle data, but if I get a moment I might have a look at the 2012 and 2011 figures as I have all the data electronically.
Enjoy :)
