It’s useful information, given with the correct IAG. But as someone working with students, parents, teachers etc, I’m not convinced it will be used as intended and worry it might encourage students to make the wrong decision. EG predicted BBC, apply for a AAA course because the tool says people were accepted at BBC.
At my institution we contextualise but for a WP applicant from an underrepresented group (e.g. care leaver) we’d be flexible on top depending on circumstances. So some of our accepted grades could look really low on there…but 99% of students wouldn’t be offered at that grade profile or confirmed.
I think it would be more useful if the info was offered on UCAS after your offers are in, to aid in that decision.
