What is the Division of Developmental Disabilities (DDD)?

The Division of Developmental Disabilities (DDD) is a service system administered through the Arizona Department of Economic Security (DES) that supports people who develop severe and/or chronic disabilities that may limit a person's ability to do the tasks related to daily living. If a child is enrolled in DDD, a support coordinator will be assigned to help determine a service plan to meet the needs of the child.
