Sutton Trust research is cited by Sean Coughlan in a piece on Post Qualification Admissions in the BBC.
Universities in the UK should stop using predicted grades when people are applying for places, say lecturers and head teachers.
A study from the University and College Union says no other developed country uses such a system of forecasts of results for university admissions.
The lecturers say most predicted grades turn out to be incorrect.
Head teachers have backed calls for a change, saying the current approach is “no longer fit for purpose”.
A study from the UCU lecturers’ union has examined admissions systems from 30 major countries and found no others using the UK’s approach of pupils applying on the basis of grades predicted by their teachers.
Clare Marchant, head of Ucas, has spoken against changing the applications timetable.
She said it would mean “structural change to either the secondary or higher education systems”.
And she warned it would be harder for poorer pupils who would have to make decisions after they had finished their exams and left school.
“It was felt that students from disadvantaged backgrounds would be less likely to have access to teachers and support in making application choices,” said Ms Marchant.
The Sutton Trust social mobility charity has said the opposite – with a report saying the current system works against talented, disadvantaged youngsters.
