Dena, Actually, the research shows that the "everybody would do better if they had more time" argument doesn't hold up under scrutiny. If the test is one that everyone is expected to finish in the regulation amount of time, giving the average student extra time does not significantly improve performance. It DOES make a difference for the student with a disability. Meantime, the ADA impacts on State and national certification testing, too. If the student with a disability qualifies for extended time when testing at the college, he/she can qualify for extended time on the certification test as well. Dr. Jane Jarrow
