¹Students who are enrolled by their parents or guardians in regular private schools and have their basic education paid through private resources but receive special education services at public expense. These students are not included under "Regular school, time inside general class."
²The 2016, 2017, and 2018 rows as well as the 2019 section include fall 2015 data for 6- to 21-year-olds in Wisconsin because fall 2016, 2017, 2018, and 2019 data were not available for children served in Wisconsin.
³The 2017 row includes fall 2016 data for 6- to 21-year-olds in Maine and Vermont because fall 2017 data were not available for children served in those states.
⁴The 2019, 2020, 2021, and 2022 data by educational environment and disability type for Iowa are imputed based on the reported fall 2018 percentage distribution by educational environment and disability type applied to the fall 2019, 2020, 2021, and 2022 total number of children served in Iowa.
⁵The 2020 data include fall 2019 data for 5- to 21-year-olds in Louisiana because fall 2020 data were not available for children served in Louisiana.
⁶Although federal law does not require that states/entities and local education agencies categorize children according to developmental delay, if this category is required by state law, they are expected to report these children in the developmental delay category.
⁷Other health impairments include having limited strength, vitality, or alertness due to chronic or acute health problems such as a heart condition, tuberculosis, rheumatic fever, nephritis, asthma, sickle cell anemia, hemophilia, epilepsy, lead poisoning, leukemia, or diabetes.
NOTE: Disability type refers to the specific disability for which a child is receiving services under IDEA. If a child has multiple types of disabilities but is receiving services for only one type of IDEA-defined disability, then the child is categorized under that specific disability. If a child is receiving services for more than one type of IDEA-defined disability, then the child is categorized under "multiple diabilites." Data in this table represent the 50 states and the District of Columbia. Prior to 2019, "school-age students" were students ages 6 to 21. Due to changes in the fall 2019 data collection, the number of 6- to 21-year-olds served in 2019 may include some 5-year-olds enrolled in kindergarten. Starting in the fall 2020 data collection, school-age children include 6- to 21-year-olds and 5-year-olds enrolled in kindergarten. Detail may not sum to totals because of rounding.
