About the Assessment: District Inclusion Rates

The tables below show the percentage of students identified as students with disabilities (SD) and/or English language learners (ELL), and provide the rate of students excluded and accommodated in two ways: as a percentage of all students in the NAEP sample, or as a percentage of students identified as SD and/or ELL. Tables that provide percentages of SD students include those identified under Section 504 of the Rehabilitation Act of 1973, as amended (Title 29 U.S.C. 794 Section 504), which prohibits discrimination on the basis of handicap in federally assisted programs and activities. In addition, the percentages are further disaggregated in the SD tables by showing those who were identified as having an Individualized Education Program (IEP) .
