‡Reporting standards not met.
¹Totals are based on overall counts of children and students by type of disability; they are not based on summing the counts reported for the individual racial/ethnic groups or the counts reported by sex. (Due to data limitations, summing the counts by disability type within each racial/ethnic group would result in a total undercount of 488 children. Because of missing data on type of disability by sex, summing the counts by disability type for males and females would also result in undercounts.)
²For 3- to 5-year-olds not yet in kindergarten, no data are available on type of disability by sex.
³For 5-year-olds in kindergarten to 21-year-olds, data include only those children served for whom both sex and type of disability were reported. About 1 percent of all 5- to 21-year-olds are excluded from this table because of missing data.
⁴Although 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.
⁵Other 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.
⁶Percentages for 5- to 21-year-olds by sex are based on total public school enrollment in kindergarten through grade 12 by sex. Data on total public school enrollment by grade are available in table 203.10, but data on total enrollment by sex are unpublished. Percentages for 3- to 21-year-olds by race/ethnicity are based on total public school enrollment in prekindergarten through grade 12 by race/ethnicity. For total public school enrollment by race/ethnicity, see table 203.60.
NOTE: Data by disability type for Iowa are imputed based on the reported 2018-19 percentage distribution by disability type applied to the 2022-23 total number of children served in Iowa. Data by disability type for South Carolina are imputed based on the reported 2021-22 percentage distribution by disability type applied to the 2022-23 total number of children served in South Carolina. Although data are for the 50 states and the District of Columbia, data limitations result in inclusion of a small (but unknown) number of students from other jurisdictions. Race categories exclude persons of Hispanic ethnicity. Detail may not sum to totals because of rounding.
