Destination of school leavers

[moved]

I am often asked by parents what percentage of pupils go to Oxbridge or Russel Group Universities from the 11+ schools. I have some data from 2007 but nothing newer. Does anyone have any information that they can provide.

The old Oxbridge data that I hold gives:

Colchester CHS 10%
Chelmsford CHS 15.5%
WHSG 7%
SHSG Not known

WHSB Not known
SHSB Not known
KEGS 15.6%
CRGS 19.5%
