1 Data do not include Vermont, for which 2007-08 and 2008-09 data were not available. In 2006-07, the total number of 3- to 21-year-olds served in Vermont was 14,010.
2 Data in the 2016-17 and 2017-18 columns include 2015-16 data for 3- to 21-year-olds in Wisconsin because 2016-17 and 2017-18 data were not available for children served in Wisconsin.
3 Data in the 2016-17 column include 2015-16 data for 3- to 5-year-olds in Nebraska because 2016-17 data were not available for children in that age group served in Nebraska.
4 Data in the 2017-18 column include 2016-17 data for 3- to 5-year-olds in Minnesota and 6- to 21-year-olds in Maine and Vermont because 2017-18 data were not available for children in those age groups served in those states.
5 Other 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.
6 For 1990-91, preschool children are not included in the counts by disability condition but are separately reported. For other years, preschool children are included in the counts by disability condition.
7 Based on total public school enrollment in prekindergarten through grade 12. For total public school enrollment, see table 203.20.
NOTE: Prior to October 1994, children and youth with disabilities were served under Chapter 1 of the Elementary and Secondary Education Act (ESEA) as well as under the Individuals with Disabilities Education Act (IDEA), Part B. Data reported in this table for years prior to 1994-95 include children ages 0-21 served under Chapter 1 of ESEA. Data are for the 50 states and the District of Columbia only. Increases since 1987-88 are due in part to new legislation enacted in fall 1986, which added a mandate for public school special education services for 3- to 5-year-old children with disabilities. Detail may not sum to totals because of rounding.
