A patchwork of testing accommodations is used in the nation's public schools to help students with disabilities and those still learning English show their command of academic content, just as their general education peers do. The list of accommodations--providing extra time, allowing the use of dictionaries, and reading test directions aloud, to name a few--has ballooned in the No Child Left Behind Act era. Some researchers estimate as many as 100 different accommodations are used for students with disabilities and English-language learners in states and local districts. But that may be changing as two groups of states labor to design new assessments for the Common Core State Standards to replace the wide variety of standardized reading and mathematics tests used now. With a rollout of the new assessments expected in 2014-15, test developers are aiming not only to streamline the types of testing supports offered to special education students and English-language learners, but also to make sure the tests are designed to be as broadly accessible as possible to all students, regardless of their profiles.
