QAA chief executive Vicki Stott said the findings were “of serious concern”.
She said her organisation would work to ensure that the university implemented the recommendations “in a timely manner” to protect academic standards.
The Scottish Funding Council, which asked the QAA to carry out the independent review, said a national review of assessment procedures at all universities would now be carried out.
Jacqui Brasted, from the SFC, said the report’s findings were “deeply concerning” and needed to be implemented “as a matter of urgency”.
A spokesperson for the University of Glasgow offered a “sincere apology” to Ethan’s family and said it fully accepted the QAA recommendations and the risks identified in its report.
“We are profoundly sorry that Ethan tragically took his own life and understand the deep distress it has caused his family,” it said.
“Since February 2025, we have worked to address the issues highlighted in the internal investigation and will implement the recommendations of the QAA review through a comprehensive plan that builds on current change projects.”
