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 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.
3 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.
4 Based on the total enrollment in public schools, prekindergarten through 12th grade. For total enrollment in public schools, 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 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. 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.
