Provisionally called PGT Choices, the site is designed to help applicants for postgraduate taught courses to think about what questions to ask when deciding what and where to study.
It is being developed by the UK’s four higher education bodies and will be available from next year.
The site will be overseen by the Postgraduate Information Steering Group, which brings together representatives from England, Wales, Scotland and Northern Ireland.
The announcement on 16 April follows the publication by the Higher Education Funding Council for England of guidance on postgraduate provision.
The advice provides clear guidelines on what type of information should be provided to potential postgraduate taught students, for example details of levels of expected engagement with the course and how it is distributed across the year.
Madeleine Atkins, Hefce chief executive, said it was “essential” that students had the right information when deciding where to study.
“Universities and colleges are already doing excellent work to provide this information,” said Professor Atkins, who announced the new guidance on postgraduate education during a speech at the Association of University Administrators annual conference in Manchester.
“The guidance that Hefce and the other UK funding bodies are publishing today, and the launch of the PGT Choices website in 2015, is designed to support them to make further improvements and enhancements,” she added.
