About the Assessment: District Inclusion Rates

NAEP has always endeavored to assess all students selected as a part of its sampling process, including students who are classified by their schools as students with disabilities (SD) and/or as English language learners (ELL). The decision to exclude any of these students is made by school personnel. School personnel are encouraged to use inclusion criteria provided by NAEP and may discuss their inclusion decisions with NAEP field staff. Some students participate with testing accommodations. Read more about the NAEP inclusion policy, including exclusion rates from current and previous assessments in all subject areas.

The tables below show the percentage of students identified as SD and/or 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 only those who were identified as having an Individualized Education Program (IEP).

NOTE: Large city includes students from all cities in the nation with populations of 250,000 or more including the participating districts. Students identified as both SD and ELL were counted only once under the combined SD and/or ELL category, but were counted separately under the SD and ELL categories. SD includes those identified under section 504. Detail may not sum to totals because of rounding.
