There now seems to be more readily available audio study materials that can be read by a screen reader. I don't know if you read using Brail but they also have brail materials (which was the only alternative study material that they offered me originally. As you can imagine it was very useless to me).
I also have the email address of the assisted director of disability policy at ETS. I honestly don't know if she is still at ETS but I have had some success getting ahold of her in the past. Feel free to contact me for her email address and contact information if you need it. She requested that I not post it on the internet.
The thing that has not really improved in testing for people with LDs, IDs and TBIs the need for a full nuro-psychological evaluation to provide accommodations which as you might know is very expensive to get accommodations for one test. Also, as of a few years ago, people who got accommodations for a reader still needed a human reader as apposed to just a screen reader which I still don't think is fair. It certainly decreases the independence of people taking the test. I don't know if that has changed. I really want to do something about with of these issues but need to get more people behind me to make a good argument for it.
