Accommodations Adaptations in assessment tools and standards to permit children with disabilities or English language learners to show what they know and can do. Adjustments may be made, for example, in the way a test is administered or presented, in the timing, in the language, or in how the child responds. The nature of the adjustment determines whether or not what is being measured or the comparability of scores is affected (Council of Chief State School Officers, 2008).
Achievement test A testing instrument, typically standardized and norm-referenced, used to measure how much a child has learned in relation to educational objectives (Council of Chief State School Officers, 2008).
