Early Intervention: What It Is and How to Access It

Early intervention offers free evaluations and therapy for children under 3 with developmental concerns, funded under IDEA Part C [1]. Parents can self-refer. Eligibility is determined by a multidisciplinary team, and services are delivered in natural environments such as the home [2].

What early intervention is and where it comes from

Early intervention is the common name for services provided under Part C of the Individuals with Disabilities Education Act (IDEA). Every U.S. state is required to operate an EI program for children from birth to their third birthday who have a developmental delay or a condition that is likely to result in one 1.

The program is federally mandated but administered at the state level, so the specific agencies, contact numbers, and eligibility thresholds vary by state 2. Services include speech-language therapy, occupational therapy, physical therapy, developmental instruction, and family support — delivered at no direct cost to families (though states may bill Medicaid or private insurance as a third-party payer, depending on state policy) 2.

Who can refer and how

One of the most important things to know: parents can self-refer. A referral does not require going through a pediatrician first, though a pediatrician referral is also a common and frequent pathway into the system 4. Other people who may make a referral include childcare providers, family members, and hospital discharge teams for babies with NICU stays or known conditions.

Once a referral is made, the state EI program is required to contact the family within a set number of days and begin the evaluation process 1. To find a state's EI program, the CDC's 'Learn the Signs. Act Early.' program maintains a state-by-state directory 3.

The evaluation process

An EI evaluation is conducted by a multidisciplinary team that may include a speech-language pathologist, an occupational therapist, a physical therapist, and/or a developmental specialist, depending on the areas of concern. It is typically done in the family's home or in a natural setting for the child 2.

The evaluation looks at development across several areas: gross motor, fine motor, communication, cognitive, social-emotional, and adaptive (self-care) skills 2. Parents share observations, and the team directly observes or plays with the child. The evaluation is free, and the family must consent before it begins. Under federal rules, the full evaluation must be completed within 45 calendar days of the referral 1.

What an IFSP is

An Individualized Family Service Plan (IFSP) is the written plan that outlines what services a child will receive, how often, in what settings, and with what goals 2. It is different from the IEP (Individualized Education Program) used in the school system for children age 3 and up — the IFSP explicitly centers the family, not just the child, and focuses on functional goals in the child's natural environment such as home and childcare settings.

Parents are active members of the IFSP team and must consent to all services 12. The IFSP is reviewed every 6 months and updated annually. As a child approaches their third birthday, the team works with the family on a transition plan to either public school special education services (Part B of IDEA) or other community services, depending on the child's needs.

Common questions about eligibility

Families sometimes assume their child will not qualify because the delay seems mild, or because they are unsure what 'counts.' Eligibility criteria vary by state — some use a specific percentage delay threshold; others qualify based on a diagnosed condition alone such as Down syndrome, hearing loss, or a known genetic condition 2.

If a child is evaluated and found not eligible at one point, the family can request re-evaluation if development changes. It is also worth knowing that evaluation is free regardless of outcome — a child does not have to qualify for services to benefit from the evaluation findings and the team's written recommendations 1. Pediatricians may also refer families into the EI system as part of routine developmental screening follow-up 4.

Common questions

Will early intervention services follow my child into school?

Early intervention under Part C of IDEA is for children birth to age 3. At age 3, services transition to the public school system under Part B of IDEA (the special education system), if the child still qualifies [1]. The IFSP team helps families navigate this transition, typically beginning around the child's second birthday.

Does my child have to have a diagnosis to qualify for early intervention?

Not in most states. EI eligibility is typically based on measured developmental delay in one or more areas, not a diagnosis [2]. A child with a significant speech delay may qualify even without a diagnosis of any specific condition.

What if I disagree with the evaluation outcome?

Parents have procedural rights under IDEA, including the right to request an independent evaluation and the right to dispute eligibility decisions [1]. The EI service coordinator is required to explain these rights at the time of the evaluation.

How do I find my state's early intervention program?

The CDC's 'Learn the Signs. Act Early.' program maintains a state-by-state directory of early intervention contacts [3]. Your child's pediatrician can also provide a referral directly into the system.

When to get care right away

  • —Any loss of skills a child previously had, at any age — this warrants prompt evaluation, not a wait-and-see approach
  • —No babbling by 12 months
  • —No single words by 16 months
  • —No two-word phrases by 24 months
  • —No walking by 18 months
  • —Concerns about hearing (a child not turning to sound, not responding to their name)
