ETS, the publisher of the SAT, offers many options for its test-takers, but the process for getting approval takes seven weeks at the minimum. In most cases, the evaluation and diagnostic testing documentation needs to have been completed within 5 years of the request for modifications.
Your child may request to use AT for his documented disability. Note that there are no additional fees for any testing modifications.
For more information on the documentation criteria, please visit Services for Students with Disabilities (College Board). You can also contact ETS Disability Services directly at 1-866-387-8602.
Also, there are several online practice sites where your child can gain practice and familiarity with the computer-based test format. Check out the practice sections and tests at:
