How can I request a change to the type of assessment in a University admission audition as a reasonable adjustment due to disability?

I am looking at a possible outcome for a performing arts University admissions appeal for my daughter, if it is allowed.

The University appeals policy states if an appeal is upheld there will be one of 4 outcomes:

1.An apology

2.Another audition without prejudice

3.Conditional offer

4.Offer

The best I can hope for is another audition but I feel that this puts my daughter in the same situation, only this time around, with adjustments. It's highly likely that she will still have extreme anxiety and there's every chance she may fail again as a result of her disability.

Would I be able to request a different, less stressful way of them testing her competence as she's being denied her chance to prove herself through no fault of her own? It seems so unfair.

I also feel uncomfortable about another audition ‘without prejudice’ which appears to be totally reliant on them being fair. Surely this could just be a case of ‘paying lip service’ and only auditioning her again to get themselves out of the discrimination complaint and then still rejecting her as they don’t want her as her parents have complained, and we may be seen as ‘difficult’

There really isn’t anyone to police what they do and say behind closed doors with admissions problems as the OIA don’t cover that process.
