Smarter Balanced Assessment Consortium: Accommodations for English Language Learners and Students with Disabilities: A Research-Based Decision Algorithm
In this paper, the authors discuss five major characteristics that an accommodation should have in order to be considered in the assessment of ELLs and SWDs: (1) Effectiveness, it must be effective in making assessments more accessible to the recipients; (2) Validity, it should not alter the focal construct; (3) Differential impact, it must be sensitive to individual student’s background; (4) Relevance, it must be relevant to the intended audience; and (5) Feasibility, it must be logistically feasible to administer. The authors say that while all five characteristics are essential for selecting appropriate accommodations for ELLs and SWDs, effectiveness and validity deserve a greater level of attention. The authors present a summary of research for some of the most commonly used accommodations and, based on the findings of the studies, provide recommendations to help SBAC’s member states in their decisions for selecting appropriate accommodations and accessibility features for ELLs and SWDs. The paper also discusses the common notions underlying accommodation and accessibility.
