David, You are right -- this system wouldn't be possible for everyone. But the fact that it IS possible for you, and you have figured out a way to provide full access for students with disabilities built in to the full access you provide to all students. Your time limit (for everyone) is "enough time". I would venture to bet that you get a much truer picture of what ALL your students know when they can focus on the content of the test, rather than the logistics. Dr. Jane Jarrow
