The Russell Group are considering the PM's proposal
Of course they are, they want to increase their tuition fees!
So I read their response to see further examples of excellent schools sponsored by universities.
The first offered is: "Queen Mary university of London co-sponsors the Drapers’ Academy in the London Borough of Havering and supports the Academy’s specialism in mathematics and science through close contact with academic departments and help with curriculum development."
Point 1: the academy doesn't have a specialism in maths and science, specialisms were scrapped years ago. Point 2: The school does have a high number of disadvantaged students, however only 42% of them achieved 5 A*-C inc M&E, which isn't much higher than the national average of 37%. Not a great advert for closing the gap.
Then we have the St Paul's Way trust school which was discussed above. An excellent school, but probably not getting many of its 11-16 cohort to uni.
Then a couple of maths sixth forms (excellent idea but not really addressing the Green Paper requirements)
A UTC - no results yet, but UTCs are closing left right and centre across the country so not likely to be a good model to follow
A primary (the Cambridge one), only just opened.
Birmingham University doing a residential and e-mentoring. This isn't running a school.
That's it. Their examples aren't much more use than the one in the Green Paper at recommending that this untested proposal be rolled out across the country to improve attainment for disadvantaged kids.
