A testing accommodation is a change to the testing environment to assist a student with special needs so that assessment can mirror classroom instruction as much as possible without invalidating test results. Only test accommodations that do not cause test results to be invalid may be used with state tests. The decision to use a particular accommodation with a student should be made on an individual basis and should take into consideration:
(a) the needs of the student and
(b) whether the student routinely receives the accommodation in classroom instruction.
