Universities are considering whether to shift the timetable of the admissions system so that applications would take place after students have their A-level results.
A review into the admissions process has been launched by Universities UK. It will examine whether it would be fairer to move away from a system based on predicted exam grades.
Paul Cottrell, head of the UCU lecturers' union, said an "overhaul of university admissions is long overdue".
The review, to be chaired by Paddy Nixon, vice-chancellor of Ulster University, says it will "draw on best practice from across the UK".
But universities in Scotland have run their own review of admissions, with an emphasis on ensuring access for applicants from deprived areas.
Universities have been under pressure over entry systems - with criticism over the increasing use of unconditional offers, in which students commit to a university place in return for being accepted regardless of their exam results.
Unconditional offers give universities more certainty over their recruitment numbers and finances - but there are concerns this is achieved at the cost of "pressure-selling" tactics on students.
There have also been challenges over whether disadvantaged students have fair access into the most selective universities. The review, due to report back next spring, will look again at the findings of an inquiry carried out under the Labour government, which called for applications to be made after A-level results - changing to what is called "post-qualification admissions".
At present, students apply and narrow down their selections before they take their A-levels - and universities make offers using the grades predicted by their schools. But most predicted grades are incorrect and there have been arguments that students would make better informed choices and rely less on guesswork if they could apply after they knew their results.
There have also been social-mobility arguments that under the current system some disadvantaged youngsters might not even apply to universities their subsequent results might have allowed them to enter.
The Sutton Trust education charity has called for an end to the use of predicted grades, with figures showing almost three-quarters of students did not achieve the grades they had been predicted.
