Coming from the big bad world of the 1970s, things have massively improved for those with disabilities. Is there room for improvement? Well, yes, there is always room for improvement in anything, however, things are changing, people are becoming more aware of the difficulties and more sensitive to those difficulties.
I was a mature student over a decade ago and I am becoming a student again later this month (at the grand old age of 53). The comparison of the two experiences is already massively different with so much more support available and so much more understanding now than before.
Back then, it was a fight to get anything, I failed an exam because reasonable adjustments were not available or advertised and to get them for the resit was an exercise in frustration and stress, this time, everything is in place even before the first module and no fight was involved.
I also noticed the change during the time my children were at university, as each child went through the process, things became easier, more streamlined, less of a fight. That is not to say it all went swimmingly, I had to mount an appeal when my middle son had his studies terminated at the end of his second year because his needs hadn't been met and he was struggling to cope and once that was won, I had to then ensure they implemented what had been promised to him when he started his degree (they did, he repeated the year and ultimately graduated)
Attitude plays a big part, I find people are more willing to work with me if I am willing to work with them and gain a mutual understanding of the reasons behind decisions and a mutual respect. Flexibility and adaptability are also positives, we can't have everything as we would like it, the world doesn't work that way and we have to be able to adapt to that and find ways to work with it. Believe me, there is nothing more frustrating than making an appointment to see someone and then finding they are up a flight of stairs and no lift available (I'm a full time wheelchair user), so I take that issue out of the equation by being proactive and checking first, asking the questions and then suggesting (not demanding) alternatives that would work for both parties.
Things are not perfect but awareness, especially of mental health issues and neuro diversity, is growing and with that, more understanding and equality.
