I think it is worrying that some schools are identifying children in primary and labelling them Oxbridge material. As others have said and proven with personal experience, people's learning trajectories are different.
We have a two tier system where some are privileged because of economic inequalities. But now we are celebrating the fact that even within the state system there are further divisions, with some very young children being dismissed from the off.
I believe in setting, streaming, differentiating and even moving throughout the system based upon ability rather than age. This way almost all children would sit exams when they are ready not at some arbitrary age. I often laugh, thinking I might still be in secondary taking my English G.C.S.E now
I don't like the idea of teachers, many of whom are not Oxbridge material themselves having the power to shape a child's future attainment in this way. For some these pronouncements become a prophecy, for others a burden. For many more though it will simply make clear what we all know to be true, very few of these children will succeed to Oxbridge. Do they need to realise this at 11 years. Realise that competition for jobs and a salary which will afford them a comfortable life is and will be quite probably out of their reach.
Once a degree was enough to ensure good future prospects and a comfortable life, before that just finishing school and before that being able to turn up on time ensured one a job and therefore access to resources such as food. As work becomes yet more scarce it would seem that teachers are able to pick out tomorrows food bank recipients and those likely to get any job, those that have a degree from not just a university but from an ever diminishing list of universities.
Anyone notice anything?
Such nonsense as early assessment of university potential requires an assessment to be made of those without potential !
