Delaware Early Intervention Autism Age 3: Your Complete Guide

In short: Delaware Early Intervention (DEI) provides services for children with autism from birth to age 3. At age 3, children transition from DEI to the school district's special education program. Families can also seek private BCBA-led ABA therapy, often covered by insurance or Medicaid. ABA For My Child is a free service to help you find vetted providers in Delaware.
Key takeaways
- Delaware Early Intervention System (DEI) supports children with developmental delays, including autism, from birth to age 3 through Child Development Watch.
- At age 3, children transition from DEI to their local school district's special education services under IDEA Part B.
- Families may pursue private ABA therapy through insurance or Medicaid alongside school-based services.
- Early diagnosis and intervention are critical; Delaware offers free evaluations through the Child Development Watch program.
Understanding Delaware Early Intervention for Autism (Under Age 3)
In Delaware, early intervention services for infants and toddlers with developmental delays or disabilities are provided through the Delaware Early Intervention System (DEI). This system is federally mandated under IDEA Part C and administered at the state level by the Delaware Department of Health and Social Services, in partnership with the Child Development Watch (CDW) program. CDW serves as the single point of entry for families concerned about their child's development, including signs of autism.
Eligibility for DEI services requires a diagnosed condition (such as autism spectrum disorder) or a significant developmental delay in one or more areas (cognitive, communication, physical, social-emotional, or adaptive). Evaluations are provided at no cost to families. If your child qualifies, you will be assigned a service coordinator who helps you develop an Individualized Family Service Plan (IFSP). The IFSP outlines goals and services, which may include speech therapy, occupational therapy, physical therapy, and developmental instruction. While DEI does not typically provide intensive ABA therapy, some families may access limited behavioral supports through the IFSP process.
Why Early Intervention Matters for Autism
Research shows that early, intensive intervention can significantly improve outcomes for children with autism. Brain development is most malleable in the first three years of life, making the early intervention window critical. In Delaware, the goal of DEI is to help children catch up to their peers and build foundational skills for communication, social interaction, and learning. For families suspecting autism, requesting an evaluation as early as possible is strongly recommended.

The Age 3 Transition from Early Intervention to School-Based Services
The transition at age 3 is one of the most important milestones for families of children with autism in Delaware. Under IDEA, when a child turns 3, they move from Part C (early intervention) to Part B (special education services through the local school district). This shift brings a change in philosophy: from a family-centered model to an educational model focused on school readiness.
How the Transition Process Works
At least 90 days before your child's third birthday, DEI service coordinators are required to hold a transition conference. During this meeting, you will discuss the child's progress, review options for continued services, and begin the process of referring the child to the local school district. Shortly after, the school district must conduct an evaluation to determine eligibility for special education under the Individuals with Disabilities Education Act (IDEA). If eligible, an Individualized Education Program (IEP) will be developed, specifying services such as specialized instruction, speech therapy, and in some cases, behavioral support. Note that the school district's services are provided at no cost to families and are designed to meet educational needs, which may differ from medical or therapeutic needs.
Planning Ahead for a Smooth Transition
Families should begin preparing for the transition at least six months before the child's third birthday. Key steps include: communicating regularly with your DEI service coordinator, gathering all evaluation reports and progress notes, attending the transition conference prepared with questions, and visiting the potential school placement if possible. It is also wise to request a transition plan in writing from the school district. Delaware school districts are required to have a transition coordinator to assist families through this process.
Continued Support: ABA Therapy for Children Age 3 and Older
Applied Behavior Analysis (ABA) therapy remains the gold standard intervention for autism after age 3. While school-based services can provide some behavior support, many families find that private, BCBA-led ABA therapy offers the intensity and consistency their child needs. ABA is a scientific approach to understanding and changing behavior, with proven effectiveness in teaching communication, social, and daily living skills. In Delaware, commercial insurance plans and Delaware Medicaid (including the Delaware First Health managed care plans) are required to cover medically necessary ABA therapy for children with an autism diagnosis.

How to Prepare for the Age 3 Transition in Delaware
Preparation is key to ensuring your child continues to receive the support they need. Here are practical tips for Delaware families:
- Start early: Begin discussing the transition with your DEI service coordinator when your child is 2.5 years old. Mark the 90-day timeline on your calendar.
- Understand the difference: Early intervention services are often provided in home or community settings; school services are typically in a classroom or therapy room within the school.
- Keep a binder: Organize all evaluations, IFSPs, IEPs, progress reports, and communication from providers. This will help you advocate effectively.
- Request an independent educational evaluation (IEE) if you disagree with the school district's evaluation. Delaware's Department of Education has guidelines for IEEs at public expense.
- Contact the Parent Information Center of Delaware (PIC) for free advocacy support and workshops on the transition process.
Costs and Insurance Coverage for Delaware ABA Therapy at Age 3
The cost of ABA therapy can vary widely, but most insurance plans in Delaware cover it. The state has an autism insurance mandate that requires large group health plans to cover behavioral health treatments, including ABA. Small group plans and individual plans may also be subject to the mandate. For families with Delaware Medicaid, ABA therapy is available as a covered benefit through the managed care organizations (MCOs) like Delaware First Health and Amerigroup. There may be copays or prior authorization requirements, but copay amounts are typically minimal for Medicaid participants.
For those without insurance coverage, some providers offer sliding scale fees or may accept fee-for-service arrangements. Additionally, Delaware's early intervention services and school-based services are free, so families should coordinate these with any private therapies to avoid duplication. ABA For My Child can help you navigate insurance questions and connect you with providers who accept your plan.
