As an academic whose DH works in support services in HE, I would recommend thinking about the following:
what aspects of the course does your DC think they might struggle with (might be group work, presentations, large lectures, etc.) - ask both the central disability services and the academic department what sort of reasonable adjustments they could support in that specific area (if the answer is very different between the two, it’s a sign that the working relationship between the two isn’t good, and that’s not a good thing)
what specific support do they provide ND students - particularly in the transition into HE. With my ND students, I have noticed such a difference if they do engage with the transition programmes offered by our support services.
What support with accommodation do they provide? Can they guarantee on campus accommodation (if that’s what your DC would prefer)? How is that accommodation managed - are there porters or wardens or RAs? DH spends a lot of his time helping ND students to navigate disputes with their flatmates, which can cause huge amounts of distress.
Are there (within affordability) options to live more ‘alone’ but in a campus environment - eg studios, or in smaller flats rather than big halls environments.
Is catered accommodation available? Is it any good? (open day tip - find out where catered students eat and if it’s open go and eat there. If they can’t get the food right on an open day, there’s no way it will be any good during term)
What training (if any) do they give teaching staff about ND? We get no formal training on teaching ND students at our institution and many of my colleagues have no idea about good practice (or willingness to learn about it).
Do they have dedicated career support available for disabled / ND students? Our careers adviser leading on this is amazing and has helped many of my former students land their dream jobs where they feel like they fit
Can they let you know what % of their ND students drop out vs. their Non ND counterparts. Unfortunately the former is likely to be higher but if it’s much much higher, it’s a sign they’re not doing a good job of supporting
