How Early Intervention Works in Maine

Save

Maine runs its Part C system through Child Development Services, a Department of Education unit that unusually also delivers Part B special education once a child turns three. This page covers who qualifies, how a family starts the process without a physician's order, why Maine's version is free, and what continues once a child ages out of Part C.

Child Development Services: Maine's Part C Program

Child Development Services (CDS) is Maine's Part C early-intervention system, serving children from birth to their third birthday who have a developmental delay or a diagnosed condition likely to cause one 1. Maine's Department of Education is the lead agency, and CDS is structured as an Intermediate Educational Unit — a single system that, unusually, also runs Part B special-education services for Maine children from age three through the end of high school, rather than handing that responsibility to a separate local school system the way most states do.

Eligibility does not depend on a specific diagnosis. A child can qualify because an evaluation finds a delay in communication, movement, thinking, social-emotional development, or self-care, or because a doctor has already identified a condition — a genetic syndrome or a significant prematurity history, for example — with a well-established likelihood of causing one 2. A family in a small coastal town and a family in Portland go through the same statewide eligibility process, since Maine does not vary its Part C criteria by region. Once eligible, the family and the CDS team build an Individualized Family Service Plan (IFSP), naming services, frequency, and setting.

Referral to a Regional CDS Site — No Doctor Needed

A parent can request an evaluation directly from their regional CDS site, and so can a pediatrician, a childcare provider, a grandparent, or anyone else with a genuine concern — Maine does not require a doctor's referral or a completed diagnosis before a family can ask for an evaluation 3.

Maine organizes CDS into regional sites that cover the whole state, from its largest cities to its most rural, sparsely populated counties, and the site serving a family's home area is the entry point regardless of who first raised the concern. Federal law then sets the pace: the evaluation and first IFSP meeting are due within 45 days of the referral 2. A service coordinator is assigned to guide the family through the process from that point on, and can explain in plain terms what each proposed service is meant to accomplish and why it was chosen.

What Early Intervention Costs in Maine: Nothing

Maine charges no family cost participation for Part C services, at any income level, which puts it in the same category as a handful of other states rather than the majority that apply some form of sliding-scale fee. Evaluation, service coordination, and every early-intervention service an eligible child receives are provided at no charge, regardless of the family's income or insurance status.

That places Maine among the states that do not scale a fee to income at all, rather than among those that charge a sliding-scale co-pay. A Maine family never has to weigh whether a recommended service will generate a bill. Insurance or Medicaid may still be billed in the background for program cost-reporting, but that billing does not create a charge the family pays, and declining to allow it does not change the services a child receives.

The Evaluation and Building the IFSP

A CDS evaluation looks across every developmental domain that could plausibly be involved — communication, motor skills, cognitive development, social-emotional growth, and self-care — rather than only the specific behavior that prompted the referral 4. The evaluation team is matched to the concern and typically includes more than one specialty, chosen based on what the family and the initial screening flag as areas of concern.

If the child qualifies, the family and the CDS team build the IFSP together, favoring services in the child's home, childcare, or another familiar setting over a clinic visit 1. The plan names concrete outcomes for that specific child, not a generic bundle of therapy types, and spells out who delivers each service and how often. It is reviewed at least twice a year, with an earlier review available if something changes.

An Autism Diagnosis Isn't Required First

No. Maine's Part C eligibility rests on a documented delay or a diagnosed condition, not on a specific diagnostic label 3. Many children begin CDS services for a delay in language, play, or social interaction well before a family has any autism evaluation scheduled, let alone completed.

That sequence exists on purpose: autism evaluations frequently involve long waits in Maine as elsewhere, and Part C was written so a child does not have to survive that wait before getting help. A Maine family does not need an autism diagnosis, or even a doctor's suspicion of one, before requesting a CDS evaluation. The two processes are independent, and pursuing both at once — a CDS referral alongside a separate request for an autism evaluation — is common and does not slow either one down.

Turning Three in Maine: Same Agency, New Plan

Maine is unusual in that CDS itself continues to be involved after a child turns three, since the same Intermediate Educational Unit that ran Part C also delivers Part B preschool and school-age special education — a structural continuity that most states, where responsibility passes to a separate local school district, do not have 5.

That continuity does not make the transition automatic. How an IFSP becomes an IEP still means a new eligibility determination, conducted by a new team under Part B's own disability categories, one of which is autism specifically 6, and CDS is expected to begin transition planning with the family well before the third birthday so services are not interrupted. Families can ask their regional CDS site directly what stays the same through that shift and what gets reassessed, and can request that existing evaluation records carry into the new eligibility process rather than starting over.

Common questions

No. A parent's or provider's concern is enough to request an evaluation from the regional CDS site. Eligibility is based on a documented developmental delay or a diagnosed condition, not a specific diagnostic label, and many children begin services well before any separate autism evaluation is even scheduled.

Nothing. Maine charges no family cost participation for Part C services — no sliding scale, no co-pay, no deductible tied to income. Evaluation, service coordination, and every early-intervention service an eligible child receives are provided at no charge to the family, regardless of income or insurance status.

A parent or guardian can contact the regional CDS site directly, and so can a pediatrician, a childcare provider, a grandparent, or any other adult with a genuine concern. Maine does not require a doctor's referral or a completed diagnosis before CDS will accept a referral and schedule an evaluation.

Federal law requires Maine to complete the evaluation and hold the first IFSP meeting within 45 days of the referral reaching the regional CDS site. A service coordinator is assigned at referral and stays involved through the evaluation and every review that follows.

Child Development Services continues to be involved, since the same agency also runs Maine's Part B preschool special education, unlike states where a separate school district takes over. The Individualized Family Service Plan is still replaced by an Individualized Education Program, built by a new team, and eligibility is reassessed under Part B's own categories.

Yes. CDS eligibility is based on a documented developmental delay or a diagnosed condition likely to cause one — autism is one possible reason a child qualifies, not a requirement. A family does not need to wait for or secure an autism diagnosis before requesting a CDS evaluation.

When Not to Wait for the Standard Timeline

  • —A child who previously used words, gestures, or social engagement stops doing so
  • —A family is told a doctor's referral or a completed diagnosis is required before a CDS site will schedule an evaluation
  • —No evaluation is scheduled and no one from the regional CDS site has made contact as the 45-day window closes

This article explains Maine's public early-intervention system for general education. It does not replace a developmental screening or evaluation by a qualified professional, and it is not legal advice about a family's specific eligibility.
