What to know
CDC’s Study to Explore Early Development (SEED) helps us learn more about autism spectrum disorder (ASD). SEED began in 2007 as one of the largest studies of young children (ages 2–5 years) with ASD in the United States. It looks at their risk factors for ASD and developmental characteristics. In 2021, SEED was expanded to learn more about the health, functioning, and needs of people with ASD and other developmental disabilities as they mature into adolescence and adulthood.
