At a Glance: College Entrance Testing Accommodations (Understood.org)
College testing companies offer four types of accommodations (Timing/Schedule, Presentation, Response, and Setting). Your child may already use accommodations like these in school. But that doesn't automatically mean he'll be allowed to use them on the SAT or ACT. Application deadlines are about tow months before your child's test date. So be sure to start the process early.
