Basically you go through the DSA evaluation that figures out how your needs can be met regarding accessibility, devices, software etc.
When I got the kit notice I contacted the supplier and asked what adaptations could be had, so got a different headset and had the laptop RAM bumped up. 4 years later it's still running fine.
DSA is called an 'assessment', but it's the opposite of stressful. Expect it to take about 1-1.5h. They put a report together that is relevant to the university to design your RAP (Reasonable Adjustment Plan). Don't worry about the RAP, it's a learning curve and it's important to give student support as much feedback as possible and voice concerns and ask questions. It's periodically reviewed and can be adapted to needs as you go. The DSA evaluation is done once. It's very important that you keep the documentation where you can find it, especially when going through SFE funding processes.
