@SoTedious this data is actually misleading. They used to publish percentage of AAA by sector which showed 62% of triple A achieved by private school pupils, which suggests their share of Oxbridge places exactly reflects top A-level performance. They have mysteriously stopped reporting this and now only show A-A* percentage whch is misleading bc with grade inflation up to 30% achieve A's, even more in some subjects. The reality is especialy for the most selective Oxbridge subjects (STEM / Maths), an A just doesn't cut it.
I would like to see the 2022 % of A taken by private school students rather than A-A, the last data that was published publicly showed 62% so no overrepresentation based on results.
The main inequality does not happen in the Oxbridge admissions stage but of course in everything that goes on before. Of course it is easier to obtain an A* with small class sizes, specialist teaching, tracking, coaching. I believe even at Sixth Form level there are many initiatives now to address this, it is likely up to GCSE that some children in the state sector don't receive the same level of support and challenge on average.
We chose private not because of Oxbridge as that is not really our aim but our supposedly outstanding state alternative (which gets as many if not more children into Oxbridge per year than the private we chose) did not offer computer science, did not set in Maths till much later, did not offer the languages we were interested in, did not offer Latin, did not offer any sports we were interested in, did not offer fixtures, had a very, very limited range of clubs, and then the staff were awfully unfriendly and strict during the banding test to the point that our daughter refused to go there.
Results wise, I am sure she could have received the same results on paper with our support or supplementary tutoring but not in the subjects that mattered to us as they weren't on offer.
