The A level results for England are here, and about 8% got an A*, while a plain A was awarded to 27% of pupils.
As far as I can tell, this means that when mapping English grades to the ECTS grading scale, A should be mapped to B, and A* to A. The mapping is not perfect, given that the ECTS system stipulates that 10% should get an A, and 25% a B, but it’s definitely very close.
I don’t understand why the education authorities in the UK don’t try to get rid of grade inflation by adopting a statistical system such as ECTS.
Otherwise, they’ll need to introduce a new grade such as A** in a few years’ time, then A***, and so on ad nauseam.
