Early Intervention vs Private Therapy
- Editorially Reviewed
- Evidence Based
- Patient Focused
In the United States, every state runs an early intervention program for children under three under Part C of the Individuals with Disabilities Education Act. It is free in most states, regardless of income or insurance, and a parent can refer their own child without a doctor's referral — which makes it the fastest and cheapest route to assessment for a young child. Early intervention is typically delivered in the home or another natural setting and centers on coaching families rather than working with the child in isolation. Private therapy may offer higher frequency, a specific approach, or shorter waits, and it costs. These aren't mutually exclusive, and many families use both.
Key takeaways
- If your child is under three in the US, start with early intervention. It is free in most states, you can refer your own child, and there is no reason to wait.
- Every state runs an early intervention program for children under three under Part C of the Individuals with Disabilities Education Act.
- The evaluation is free with no income test. It is not means-tested and not insurance-dependent.
- What services cost afterward depends on the state: most charge nothing, a minority use a sliding scale, and no state may deny services to a family that cannot pay.
- You can refer your own child. There is no doctor's referral and no gatekeeping.
- The session frequency may be lower than expected, and that is the model rather than a shortfall: early intervention coaches the parent because what happens in daily routines matters more than session hours.
- That model suits some families and not others. Wanting more direct work with the child is a legitimate reason to add private therapy.
- Eligibility criteria vary by state, so a child who qualifies in one may not in another. If yours does not qualify, ask what the threshold was and whether re-referral later is appropriate.
The short answer
If your child is under three in the US, start with early intervention. It's free in most states, you can refer your own child, and there's no reason to wait.
Whether you add private therapy is a separate question you can answer afterwards.
Side by side
| Early intervention (Part C) | Private therapy | |
|---|---|---|
| Age | Birth to third birthday | Any age |
| Cost | Free, regardless of income or insurance | Paid or insurance-funded |
| Referral | A parent can self-refer | Often needs a physician referral for insurance |
| Eligibility | Assessed developmental delay or a qualifying condition; criteria vary by state | Anyone who can access it |
| Where | Home or another natural setting | Clinic, sometimes home or school |
| Model | Family coaching — teaching parents to embed strategies into daily routines | Usually direct therapy with the child |
| Frequency | Often lower — sometimes every two weeks or monthly | Often weekly or more |
| Team | Coordinated across disciplines, with a service coordinator | Usually discipline by discipline |
| Transition | Ends at three; transfers to school district services | Continues |
What surprises families about early intervention
The evaluation is free, with no income test. Not means-tested, not insurance-dependent. What services cost afterward depends on the state: most charge nothing, a minority use a sliding scale based on income, and no state may deny services to a family that cannot pay. Many families assume otherwise and never call.
You can refer your own child. No doctor's referral, no gatekeeping. Search "[your state] early intervention" and call.
The frequency may be lower than expected, and that's the model rather than a shortfall. Early intervention is built on the premise that what happens in daily routines matters more than session hours — so the therapist coaches you, and you do the work between visits.
That model has real merit and it doesn't suit every family. Some parents find it empowering. Others want more direct work with the child, which is a legitimate reason to add private therapy.
Eligibility criteria vary by state. A child who qualifies in one state may not in another. If your child doesn't qualify, ask what the threshold was and whether re-referral later is appropriate.
Where private therapy adds something
- Higher frequency, where more intensity is wanted
- A specific approach — Ayres Sensory Integration, a named literacy program, a particular feeding method
- Direct work with the child, rather than parent coaching
- Shorter waits, sometimes
- Continuity past three, without the transition break
- Where a child doesn't meet EI eligibility but you still have concerns
Using both
Common, and usually complementary rather than duplicative.
Tell each provider about the other. Goals should coordinate, and duplicated goals across two providers wastes everyone's effort.
Where insurance funds private therapy alongside free EI, some plans have questions about concurrent services. Worth asking.
The transition at three
Early intervention ends at the third birthday. Services transfer to the school district under IDEA Part B, and eligibility criteria are different — some children who qualified for EI don't qualify for school services, and vice versa.
The transition should be planned in advance, typically starting around six months before. If nobody has raised it by age two and a half, ask.
If your child doesn't qualify for school services, private therapy or a Section 504 plan may be the route. → IEPs and 504 plans
