The petition is not only about the degree itself. It is also about what comes afterwards, including the reality of trying to enter the relevant profession or job market.
I am trying to envision how this information would realistically be collected and made available and in my opinion, you are asking for the impossible.
That can involve further requirements, experience, additional costs and the practical difficulty of actually getting into the work.
First, because the labour market is changing all the time. Completely outside of a university’s control. No one knows what wider global economic or political events will happen to impact the labour market. Let’s think about covid, Brexit, Russia Ukraine war, Trump bombing Iran, the development of generative AI. All of those outside a university’s control but you’re asking them to detail the practical difficultly of actually getting into work? That changes year to year.
Second, there are 100’s of degree courses being offered by any single university and you expect them to be able to provide all of this information for each course? Plus, see the first point.
Third, realistic employment information sounds as if you mean what are the realistic chances of getting a graduate job post degree, but job prospects do not come from just the degree itself, but instead multiple variables including the students degree classification, the university itself (a huge difference applying for jobs with Cambridge or Imperial as the degree provider vs a low ranked university), what the individual student did during their degree, what extra curricular activities and roles they undertook, what internships they applied for, etc etc. How does a university calculate job prospects on that basis?
The petition is about the university as an institution providing clearer information before enrolment about what a degree does and does not qualify someone to do, any known further requirements, and realistic employment information
Plus, what @HelenaWilson said… any one course has the potential to lead to 100’s of different career paths or none at all. It is very difficult to predict labour market needs. Oddly, the impact of GenAI/AI is leading many employers to seek more Humanities degree students and suddenly computer science or maths is no longer the safest route into a financial career. That’s unexpected.
I’m assuming that you’re either a disappointed parent or disappointed graduate with debt and struggling to get a job and now angry at your university? I fully sympathise but there’s never been a guarantee of a job that comes with the diploma. And what you’re asking for, beyond what many universities already do (collect job and salary data on their graduates one year after graduating) I cannot see as feasible.
