Higher education needs a mechanism to challenge student accommodations

You need to be more explicit about how the diligent and industrious students are being screwed. In my experience the only accommodations available to disabled students are a) extra time/breaks/separate rooms for exams, b) availability of an extension for assignments (usually 1 week), c) provision for them to contact staff for clarifications, review of assignment plans etc, d) provision of specialist software (e.g. for dyslexia aids), e) easier path to obtaining a resit with no mark cap. These are only granted with medical evidence. For many disabilities, in many parts of the UK the waiting list for diagnosis is as much as 2 years. Of the above the only ones that might be attractive to diligent non-disabled students are extra time. But it is worth pointing out unis can't make time. They are not giving the students more time, they are letting them use more of their own. Meaning they are not using it for casual work, or extra study, or social activities to give them a proper study/life balance. The secret to making a level playing field is for professors to change their practice so it is inclusive to all, and so any accommodations needed are minimal, or non-existent.
