What is the difference between an accommodation and a modification?
Currently there is no national agreement on the terms used to refer to accommodations, so the answer to this can differ by state. However, many states do define accommodation and modification in different ways. An accommodation, in some states, generally refers to a change in the way a test is administered, or a change in the testing environment, with the added characteristic that the construct being measured does not change. A modification, in some states, refers to a change to the test that is thought to change the construct measured. It is important to remember that most states do not have empirical evidence about construct validity and accommodations and that these distinctions are made by professional judgment, not empirical evidence.
