You need some evidence - usually and Ed psych report and it has to be less than two years old. I was planning to get one shortly partly for this purpose but also my brother interesting since last one was when he was 9 ! It is quite a long winded process to go through but the support on offer is substantial so well worth it and fairly standard across all unis and covers the whole range of support required whether for academic support, living arrangements or mh
It’s worth researching and making sure they know what’s on offer and the evidence required before they go. DS tried some speech to text software at the start of secondary school but I think it was too early and he didn’t have the maturity and tech savvy to make it worth while / I think he should try out a few things next year to have another go. A lot if things can be downloaded free for a trial.
