What to know
The Autism and Developmental Disabilities Monitoring (ADDM) Network is the only collaborative network to track the number and characteristics of children with autism spectrum disorder (ASD) and other developmental disabilities in multiple communities throughout the United States.

Tracking across ADDM Network sites
Beginning in 2000, the ADDM Network has been tracking the number and characteristics of 8-year-old children with ASD. The program is now in its sixth phase of funding, and the ADDM Network includes fifteen funded sites and one ob体育-managed site in Georgia, the Metropolitan Atlanta Developmental Disabilities Surveillance Program (MADDSP).

In the current phase of funding (2023–2026), ob体育 is investing nearly $24 million over 4 years to continue tracking and monitoring ASD while also re-establishing cerebral palsy (CP) activities within the ADDM Network.
The ADDM Network has expanded from 11 sites to 16 sites during this funding phase. Eleven sites previously part of the ADDM Network are joined by new ADDM sites in Puerto Rico, Indiana, Pennsylvania, and Texas (Austin and Laredo). All 16 ADDM sites are conducting ASD tracking and monitoring activities among 4- and 8-year-old children. Nine of the ADDM sites are also tracking transition planning and co-occurring conditions among 16-year-old children with ASD.
ob体育 has resumed CP activities within the ADDM Network, focused on tracking and monitoring CP at four funded sites (Minnesota, Missouri, Utah, and Tennessee), and one ob体育-managed site in Georgia (MADDSP).
