Everything parents need to know about Early Intervention — how to get your child evaluated, what services are available, and how to navigate the transition to school at age 3.
Early Intervention (EI) is a federally funded program that provides free or low-cost developmental services to children from birth through age 3. It is authorized under Part C of the Individuals with Disabilities Education Act (IDEA) — the same federal law that governs special education in public schools.
The goal of Early Intervention is to support children who are showing signs of developmental delay or disability during the most critical window for brain development. Research consistently shows that earlier intervention produces better long-term outcomes in communication, learning, behavior, and independence.
Most families who qualify for EI never access it — not because services are unavailable, but because no one told them the program exists. If your child is under age 3 and you have any concern about their development, you have the legal right to request a free evaluation today.
You can start the Early Intervention process today. No referral needed — any parent can self-refer.
Call 211 and ask for Early Intervention, search your state name plus 'Early Intervention program,' or ask your child's pediatrician for a referral to the state program.
Say or write: 'I am requesting a free Early Intervention evaluation for my child. I am concerned about their development in [describe the area].' Keep a copy of your request.
The state program has 45 days from your referral to complete a free, comprehensive evaluation covering all developmental areas. It is done in your home or a convenient location.
The team tells you whether your child qualifies. If eligible, you move to an IFSP meeting. If not, you can request a written explanation and re-evaluate if concerns continue.
An Individualized Family Service Plan is created at a team meeting. Services must begin as quickly as possible after the IFSP is signed.
To qualify for EI, your child must be under age 3 AND meet one of these three criteria. When in doubt — request an evaluation. The only way to know for sure is to have your child assessed.
Your child is significantly behind in communication, cognitive, physical, social/emotional, or adaptive development — even without a formal diagnosis.
A confirmed diagnosis that is likely to result in delay — autism, Down syndrome, cerebral palsy, hearing loss, vision impairment, chromosomal conditions, and more.
Some states serve children at risk due to premature birth, low birth weight, prenatal substance exposure, or significant family risk factors. Ask your state's program.
Your child does not need a formal diagnosis to qualify for Early Intervention. A measurable developmental delay is enough. If your child is showing signs of delay in any area — language, motor, social, or cognitive development — request an evaluation now. Waiting until age 3 means missing the most impactful window for intervention.
Early Intervention can include any service your child needs to support their development. Services are written into the IFSP and provided in your home or community setting.
For delays in talking, understanding language, feeding, and communication. Often the most requested EI service.
For delays in fine motor skills, sensory processing, self-care (feeding, dressing), and play skills.
For delays in gross motor skills — sitting, crawling, pulling to stand, walking, and balance.
A developmental specialist works with your child on overall development. Commonly written into IFSPs as a bridge across skill areas.
Available in some states for children with autism or significant behavioral needs. Contact your state program to confirm availability.
A dedicated coordinator who helps you navigate the EI system, connect to resources, and prepare for the transition to school at age 3.
Helps you learn strategies to support your child's development at home, between therapy sessions, and during daily routines.
Communication apps, adaptive equipment, and other devices that help your child communicate, move, or participate in daily life.
Your child is not limited to one service. If they need speech therapy, OT, and special instruction, all three can be written into the IFSP.
The Individualized Family Service Plan (IFSP) is the document that guides everything in your child's Early Intervention program. Think of it as a blueprint — it describes where your child is now, where you want them to go, and exactly how the team will help you get there.
Describes where your child is right now — their current skills across all developmental areas. Should match what you observe at home, not just clinic test scores.
Goals for your family — not just your child. EI is family-centered, so the plan can address what your family needs to support your child's development.
Specific, measurable goals your child is working toward. Each outcome should describe a functional skill in your child's everyday life.
Exactly what services your child will receive — type, frequency, duration, and who provides them. Everything must be written in before services can begin.
Explains where services will be provided (your home, daycare, community) and why. Services should happen in natural settings whenever possible.
How your child will move to the next program when they turn 3. Must be started at least 90 days before your child's third birthday.
At age 3, Early Intervention ends and your child moves to the public school system under Part B of IDEA. This transition does NOT happen automatically — you must take action before your child turns 3 or there may be a gap in services.
Your EI service coordinator must schedule a transition conference. Don't wait for them — ask for it early.
You, your EI team, and a school district representative meet. Sign consent for EI records to be sent to the school district.
After the conference, formally request an evaluation from the school district in writing. Keep a copy. This is NOT automatic.
The school has 60 days from your written request to complete the evaluation and hold an eligibility meeting.
If eligible, an IEP must be in place and services must begin on your child's third birthday — or the first school day after.
Under Part C of IDEA, you have strong legal rights throughout the Early Intervention process. These rights cannot be waived by the program.
You can request a free evaluation at any point — no referral needed. The program must respond to your request within a reasonable timeframe.
You are a full member of your child's team. No service can be added, changed, or removed without your written consent.
You must give written consent before any evaluation, before services begin, and before changes are made. You can withdraw consent at any time.
If you disagree with the EI evaluation results, you have the right to request an independent evaluation. Depending on your state, this may be at public expense.
The program must notify you in writing before making any changes to your child's services — or before refusing to make changes you have requested.
If you disagree with any decision, you have the right to file a complaint, request mediation, or request a due process hearing.

If your child is under age 3 and you have any concern about their development, the first step is always the same: request a free evaluation. You have nothing to lose — and everything to gain.
Contact your state's Early Intervention program directly — you do not need a referral from a doctor. You can self-refer by calling, emailing, or writing a simple request stating you are concerned about your child's development. The program has 45 days to complete the evaluation from the time they receive your referral. To find your state's program, call 211 or search your state name plus 'Early Intervention program.'
The evaluation is always free — you cannot be charged. The services are also free in most states, though some states may charge a sliding-scale fee based on family income for ongoing services. The evaluation and the right to services are guaranteed under federal law (Part C of IDEA), so you should never be turned away due to cost.
No. Early Intervention research consistently shows that earlier is better — the brain develops most rapidly in the first three years of life. If you have any concern about your child's development, you have the legal right to request a free evaluation at any time, regardless of what your pediatrician says. Waiting is always a risk when it comes to developmental delays. You can request an evaluation and decide from there — there is nothing to lose.
The IFSP (Individualized Family Service Plan) is the document that guides your child's Early Intervention program. Unlike the IEP (used in school), the IFSP is family-centered — it includes outcomes for your family, not just your child. Services are delivered in natural environments like your home or daycare. The IFSP is reviewed every 6 months (IEPs are reviewed annually). When your child turns 3, the IFSP is replaced by an IEP through the school district.
No. Early Intervention ends at age 3, and services do not automatically transfer to the school district. You must actively request an evaluation from your local school district before your child's third birthday. The transition conference must happen at least 90 days before that date. If you do not submit a written evaluation request to the school district, there may be a gap in services after EI ends.
You have the right to request an independent evaluation if you disagree with the EI team's findings. Depending on your state, this may be at public expense. You also have the right to file a complaint, request mediation, or request a due process hearing at any point. Your rights are protected under Part C of IDEA. If you are unsure what to do, contact your state's Parent Training and Information Center (PTI) — they provide free guidance.
