But, presumably, if there is an issue, the PT then has to deal with it? The first email itself is five minutes. But then the student responds saying, "I'm struggling with workload." Which could mean a million things. So there's another email to set up a meeting (and there also might be a "can I just send you some questions by email?" diversion). Which the student might or might not attend. So there's a follow up email, if they don't, and another meeting to schedule. If they do attend, perhaps we spend 30 minutes getting to the bottom of the problem, and I offer advice, but probably worry that it's trite (is saying, "lets make a schedule" actually going to help a student with severe ADHD?). And then I email next week to say, how's the workload going? And the answer is, oh, still not great. So we have another meeting to discuss what they tried and what worked... And I probably email disability services to flag with them, and possibly wellbeing, and possibly also the senior tutor in the department.
I want inclusive education, and I think students like your DD should have support to learn. But it's not in my workload capacity to provide it at the level above.
What your DD needs is a disability mentor whose job it is to do this check in, help her manage her ADHD, and help her initiate contact with her personal tutor about specific queries/struggles with her academic work. DSA can fund this because its something that's a demand over and above what students would usually require.
