SEED 3 is the third phase of a multi-year, multi-state research study to compare children with autism and other developmental delays to children without these delays. This study is funded by the Centers for Disease Control and Prevention (CDC) as part of the Center for Autism and Developmental Disabilities Research and Epidemiology (CADDRE) Network. This network is composed of six research sites across the country. The North Carolina site is located at UNC Chapel Hill.

During the first and second phases of SEED, the other sites participating were in California, Colorado, Georgia, Maryland and Pennsylvania. Together all sites enrolled approximately 7000 children 2 1/2 to 5 years old with North Carolina enrolling about 1350 children.

During this third phase of SEED, two sites left the group and two new sites joined. For SEED 3, the other participating sites are in Colorado, Georgia, Maryland, Missouri, and Wisconsin. Together these sites will enroll approximately 3300 children 2 ½ to 5 years old with North Carolina enrolling about 600 children.
