Early Start: Transition at Age 3—What Happens Next?

The California Department of Developmental Services (“DDS”) provides critical care, services, and resources to individuals with developmental disabilities. For young children, this care is administered primarily through the DDS Early Start Program. However, this program is only available for infants and toddlers between the ages of 0-3. After that, children transition to other forms of care. This article outlines how this process unfolds so you can know what to expect when your young child turns three.

Transitioning From Early Start to Special Education

Turning three years old marks a major transition point for young children receiving DDS services. That’s because this is when the child will shift from early intervention into the next phase of services. This transition is often referred to as “Part C to Part B transition,” with Part C referring to the Early Start program and Part B referring to special education services for children participating in DDS.

As a child approaches their third birthday, the regional center coordinating Early Start begins a formal transition planning process. This typically starts at least six months before the child turns three. The regional center, family, and other service providers meet to discuss the child’s progress, needs, and eligibility for future supports. As always, parents play a central role in this process, helping determine what services best fit their child as they move into preschool and beyond.

If a child is eligible under the Lanterman Act or other California DDS criteria, they may continue to receive developmental services through the regional center. These services could include various types of therapy, behavioral supports, respite for family caregivers, and coordination with school-based programs.

Most typically, services shift to the local school district, which may provide special education and related supports under the Individuals with Disabilities Education Act (IDEA), Part B.

This transition ensures that children do not lose support when Early Start ends. By planning ahead, families and DDS work together to create a smooth shift into preschool years, fostering continued growth and development.
