Note:The "Total Served By IDEA Age 6-21" column includes the disabilities listed in this table plus the disabilities listed in two other tables.

The criteria for being served for a specific disability type are not provided due to the different criteria states set for students with disabilities to be served for specific disability types. However, the disability type "Developmental Delay" is applicable only to people age 3-9 years.

To calculate the percent of people served in a state under IDEA for a specific disability type, divide the number served for the specific disability type by the total number served by IDEA in the state and multiply the result by 100. Example: Calculate the percent of people in Kansas served for Autism. This calculation would be: 471/52,702=.0089 and .0089x100=.89%
