Three universities are being investigated after a “sharp rise” in the number of first class and upper second class grades awarded to students.
It is believed to be the first time the Office for Students (OfS) has officially probed institutions over grade inflation since gaining new powers earlier this year.
The regulator refused to name the universities under investigation on Friday. “We expect to publish further details in due course, as our investigations progress,” it said.
The OfS said it had “identified potential concerns that require further scrutiny” at the institutions. But it stressed this was not to be interpreted as wrongdoing at this stage.
