People with disabilities such as visual impairment, dyslexia or attention-deficit hyperactivity disorder say they are entitled to extra time, special software or other accommodations that will best ensure that the test reflects their aptitude rather than their disability.
Testing companies say they don't have to provide accommodations if they think the requests are unreasonable, or if they think the applicant hasn't proved they need the accommodation.
The Government Accountability Office (GAO) found that "almost all" of the nine testing companies it studied did not change any practices in response to regulations issued this spring designed to broaden the definition of disability and reduce burdensome documentation.
