Definition: Number of public school students receiving special education services, by primary disability type (e.g., in 2018, 112,318 California students were enrolled in special education for autism).Percentage of public school students receiving special education services, by primary disability type (e.g., among California students enrolled in special education in 2018, 14.5% were enrolled for autism).
Footnote: Years presented are the final year of a school year (e.g., 2017-2018 is shown as 2018). California data include children and youth ages 0-22, whereas data for the U.S. include those ages 3-21. Disability types reflect primary disability categories as defined here. Some percentages for deaf-blindness and established medical disability have been rounded to 0.0% and should not be interpreted as no cases reported. U.S. data may not sum to 100% due to differences in disability categories reported at the national level. The notation S refers to percentages that have been suppressed because there were fewer than 280 total special education enrollees, and numbers that have been suppressed because there were between 1 and 10 enrollees in that group. N/A means that data are not available or that the percentage was far above average for that year (more than 3 standard deviations above the mean).
