DSA support is separate to the univeristy support, they always say just because you are receiving DSA it doesn't mean that the extra support in terms of the uni will happen automatically.
DSA stuff is seperate, so has he applied for that? If so has she had her needs assessment to get the software etc. She needs to apply through student finance website initially, it will be on his home page, that involves uploading evidence initially onto the portal then they asses it and send a DSA1 letter saying whether they've approved her application or not. So apply through student finance and upload all the evidence, if it's for a learning need e.g dyslexia then they have to upload the report from the SPLD and diagnostic report. ECHPs don't apply at university or to DSA, they don't use that at all - however when he communicates with univeristy he can use some of the stuff he knows is helpful from before and ask for those similar reasonable adjustments.
After that they send him a link to book a DSA Needs Assessment through capita often, that isn't a test or anything, as he's already gotten approved. That's where they'll decide software things, a specialist study tutor, equipment to record lectures, assistive technology software etc.
At the end they then send a DSA2 letter. Then at the end they ask her if hewants this sent to the univeristy, make sure he consents or otherwise they won't send it. They then send the report to student finance, then she'll get a DSA2 letter from SFE saying what they've approved and then he just needs to liase with them as they send him the equipment. It's actually quite simple but the process has quite a few steps.
He needs to seperately contact his univeristy disability service - they'll have something on the website to send them a form with evidence again of your condition. Then he needs have a meeting with his university Disabiltiy service, they are often called disability advisors, they can make him an LSP/ISP and that will have details on exam arrangements, teaching arrangements etc.g lecture material 24h before etc, not asking questions on the spot, arrangements for things like coursework, presentations etc. They'll likely have extra library induction and study support workshops for disabled students as well
. They'll have plenty of information on the website or the university specific portal - so have a good look at everything on there, get him to fill the form uploading evidenxe to the univeristy and also informing them of his struggles etc again the evidence needs to be an SPLD report etc. If not they'll be information on the website/student portal with how to contact them to get support in place. You need to do both separately but at the end if he consents at his DSA Needs Assessment, then they'll send his DSA2 letter to his univeristy team as well but again that doesn't mean he'll automatically get other support from the univeristy - if he doesn't contact them and liase with them separately. I hope this all makes sense and you can pass it on to him.
