What early intervention actually is
Early intervention (often shortened to EI) is a publicly funded program that every state operates under Part C of the Individuals with Disabilities Education Act. It serves children from birth until they turn 3 who have a developmental delay or a condition likely to cause one. Late talking is one of the most common reasons families call.
Each state gives its program its own name and runs it through its own agency, which is why a neighbor in another state may describe something that sounds different from what you find. The structure underneath is the same everywhere: a referral, a free evaluation, and, if your child qualifies, a written plan called an IFSP (Individualized Family Service Plan) with services delivered mostly in your home or your child's daycare.
Who qualifies
States set their own eligibility thresholds, usually expressed as a percentage of delay in one or more areas of development. Some states also cover children at risk of delay. Two things are true in every state:
- You do not need a medical diagnosis to be evaluated or to qualify. A speech delay by itself can be enough.
- The evaluation is free whether or not your child ends up qualifying.
If your child has a diagnosed condition such as Down syndrome or hearing loss, most states qualify them automatically. If your child is a late talker with no other concerns, the evaluation will look at how they understand language, how they communicate (words, gestures, pointing), and how they play.
How to refer your child this week
- Find your state's program. The federal ECTA Center keeps the official list of Part C coordinators and program contacts for every state. The CDC's Learn the Signs. Act Early. program is another route to the same door.
- Call and say the words "I want to refer my child for an early intervention evaluation." That sentence starts a legal clock. You do not need to prove anything on the phone.
- Write down the date of your referral. Federal rules require the program to complete the evaluation and, if eligible, hold the first IFSP meeting within 45 days of that referral.
- Do the evaluation. It usually happens at home, takes an hour or two, and looks like structured play. You will be asked lots of questions; your answers count as data.
- Read the plan before you sign. The IFSP lists goals and how many therapy visits your child gets. You can push back on frequency, and you can ask for it to be revisited later.
What it costs
The referral and evaluation are free everywhere; federal law requires it. Services after that depend on the state: many provide everything at no cost to families, and others use sliding-scale fees or bill your insurance or Medicaid with your consent. Ask your service coordinator two direct questions: "Is there any family fee in this state?" and "Will you bill my insurance, and can I decline that?" If your child has Medicaid, the EPSDT benefit can also cover speech therapy separately. Our Medicaid speech therapy guide covers that path.
What happens at age 3
Part C ends on your child's third birthday, but support does not have to. Your EI program is required to plan the handoff, and a transition conference happens at least 90 days before your child turns 3. From age 3 on, free evaluations and services run through your local school district under Part B of the same law, even if your child is not enrolled in preschool. If your child is already close to 3, skip EI and contact your school district directly to request an evaluation in writing.
While you wait
The 45-day window feels long when you are worried. Daily practice at home moves the needle in the meantime: narrate routines, pause and wait after questions, and reward every attempt at communication, spoken or not. Our toddler not talking hub and daily speech routines hub give you concrete scripts, and the NIDCD speech and language milestones page shows what typically develops when.
Frequently asked questions
Do I need a doctor's referral for early intervention?
No. In every state, a parent can refer their own child directly to the Part C early intervention program. A doctor's note can help, but it is not required to request the free evaluation.
How much does early intervention cost?
The evaluation is free in all 50 states. Services are free in many states; others charge sliding-scale fees based on income or bill insurance with your consent. Ask your service coordinator what your state does before you sign the IFSP.
What if my child doesn't qualify?
You can ask what the state's eligibility threshold is, request a re-evaluation in a few months if concerns continue, and pursue speech therapy through Medicaid EPSDT, private insurance, or private pay in the meantime. Not qualifying for EI does not mean nothing is wrong or that nothing can be done.
Will using early intervention stop us from doing private speech therapy?
No. Families often do both. EI services are yours by law if your child qualifies, and private therapy is a separate decision. Therapists on both sides usually coordinate if you connect them.
We speak two languages at home. Does that change the evaluation?
It should not count against your child. Evaluators are supposed to assess across both languages, and raising a child bilingual does not cause speech delay. Tell the program your home languages when you call so they bring the right evaluator or interpreter.
