Katherine, I'm sorry to hear about this situation & I wish I had some words of wisdom to help but to me you've done what you should be doing. I would say this, at the risk of sounding harsh & unfeeling toward your student: if she has not claimed her disability you are not under any obligation to provide accommodations. A student simply claiming to have a disability does not guarantee these, rather they must present the correct documentation. I realize this doesn't help relieve the frustrations, but she cannot push this too far without the proper support. Ryan Meers, Ph.D.
