In order to study the effects on the assessment, NAEP collects information about accommodations needed for students with disabilities (SD) and English language learners (ELL) by asking the school staff most familiar with each student to complete the appropriate SD or ELL questionnaire. The information gathered in this way has informed research for several years, including estimates of how excluded students may have performed and measures of change in inclusion rates.
