If you’re looking for information about disabilities in infants, toddlers, children, and youth with disabilities, you’ve come to the right place! NICHCY offers information and connections to the full spectrum of disabilities in children, including developmental delays and rare disorders.

Use the links below to learn about typical developmental milestones in childhood, specific disabilities and disorders, and the disability categories in our nation’s special education law (IDEA) that qualify a child for special education services. NICHCY can also put you in contact with the wide range of organizations, conferences, and resources that are focused on specific disabilities and the disability network at large.


Developmental Milestones
This section of the website explores the typical developmental stages and milestones that pediatricians and others use to monitor children’s growth and progress over time. Learn about the sequence and timing of a typical child’s earliest development and access resources to learn more.

Categories of Disability under IDEA Law
The IDEA includes 14 primary terms under the main definition of “a child with a disability.” These federal definitions guide how states define who is eligible for a free appropriate public education under special education law.

Fact Sheets on Specific Disabilities
NICHCY offers brief, but detailed fact sheets on specific disabilities. Each fact sheet defines the disability, describes its characteristics, offers tips for parents and teachers, and connects you with companion resources and disability organizations that offer more information and assistance.


NOTICE: The National Dissemination Center for Children with Disabilities (NICHCY) is no longer in operation. Our funding from the U.S. Department of Education’s Office of Special Education Programs (OSEP) ended on September 30, 2013. Our website and all its free resources will remain available until September 30, 2014.
