Britain ’s higher education minister David Lammy has warned elite universities that they risk undermining public confidence in their admissions systems by demanding pupils score the new A* grade in their A-level results from next year, The Guardian reports. Lammy said universities planning to use the A* grades to select students risk unfairly rejecting candidates whose schools fail to accurately predict their ability to get an A*. The new grade will be awarded to students who get top scores in their A-levels. It was introduced in response to universities ’ concerns that they can no longer distinguish between straight A students. Last year more than a quarter of all students were awarded an A grade. Applications to most universities depend on schools ’ predictions of students ’ grades. There are also concerns that the A* will cement independent schools ’ dominance of places at the top institutions. Last month Cambridge, Imperial College London and University College London confirmed they would use the A* in their admissions processes. However, other top universities including Oxford, London School of Economics and Durham have ruled out the use of A~ until it has been properly reviewed.
