How Early Intervention Works in Maryland

Save

Every state runs the same federal early intervention mandate differently, and Maryland's version is built around 24 local programs rather than one central office. This guide walks through how the Maryland Infants and Toddlers Program is organized, who qualifies without needing an autism diagnosis first, how a family starts the process on their own, what the timeline and cost actually look like, and what changes once a child turns three.

What Early Intervention Under Part C Actually Covers

Part C of the Individuals with Disabilities Education Act is the federal law behind early intervention: a system of services for infants and toddlers from birth to age 3 who have a disability or a developmental delay, delivered in the settings where the child already spends their day, rather than a clinic-only model 1. It exists in every state, funded partly by federal grants and partly by the state itself, and every state must designate one agency to run it.

A family does not need a completed diagnosis of any kind, autism included, to start this process. Individualized Family Service Plan (IFSP) is the document that early intervention produces once a child is found eligible — a plan built around the family's own routines and goals, not a generic curriculum, and it replaces a diagnosis as the thing that actually unlocks services.

The Maryland Infants and Toddlers Program: Maryland's Part C System

Maryland's Part C system is called the Maryland Infants and Toddlers Program, and the state's designated lead agency is the Maryland State Department of Education, through its Division of Early Intervention and Special Education Services 2. Every state names its own lead agency under Part C — some place it inside a health department, some inside human services, Maryland places it inside education, and that choice shapes which state office ultimately answers a family's question when something isn't working.

Naming a lead agency does not mean that one office runs every intake in the state directly. MSDE sets statewide eligibility policy, funding, and oversight, but the day-to-day work of intake, evaluation, and service coordination is carried out locally, which the next section covers.

Why Maryland Runs Early Intervention Through 24 Local Programs

Maryland delivers the Infants and Toddlers Program through 24 separate Local Infants and Toddlers Programs, one for each of the state's 23 counties plus Baltimore City, rather than through a single statewide office that a family calls no matter where they live. Each local program is responsible for intake, evaluation, and service coordination for children in that jurisdiction, operating under statewide MSDE policy but with its own local staff and its own point of contact.

That structure means the first call a Maryland family makes is to their county's own program, not a state hotline, and it is also why two families in different Maryland counties can describe slightly different day-to-day experiences of the same statewide program. A family that moves from one Maryland county to another during early intervention keeps its Part C eligibility, but its point of contact changes with the move.

Who Qualifies — and Why an Autism Diagnosis Isn't a Prerequisite

A child qualifies for Part C in Maryland in one of two ways: a diagnosed physical or mental condition with a high probability of causing developmental delay, or a documented delay itself, measured against a threshold the state sets in its own regulations, across five developmental domains — cognitive, physical, communication, social-emotional, and adaptive 3. Autism is a diagnosed condition, so a child with an autism diagnosis, or a strong suspicion backed by a physician or psychologist, typically qualifies through the first path without needing to demonstrate a specific percentage of delay at all.

Maryland's own delay threshold, like every state's, is set in state regulation and can differ from a neighboring state's cutoff, so a family relocating across a state line should not assume identical criteria apply. A missed or borderline score on one evaluation is not the end of the road — a family can request reevaluation, and eligibility can also be established through a qualified evaluator's informed clinical opinion when standardized scores alone sit right at the edge.

How to Refer a Child in Maryland Without a Doctor's Visit

A parent, grandparent, child care provider, or any other concerned adult can refer a child directly to their county's Local Infants and Toddlers Program; Maryland does not require a physician's referral before an evaluation can be scheduled 4. A pediatrician's referral can still help, mainly by attaching existing records to the file, but it is not a gate a family has to wait behind.

Because eligibility does not depend on a completed diagnosis, a Maryland family can start this process the same week a concern comes up, rather than waiting for a separate autism or developmental evaluation to finish first 5. The local program's intake staff, not a private clinic, is who receives that first call, and they are the ones who schedule the evaluation and assign a service coordinator once eligibility is confirmed.

What It Costs a Family, and the 45-Day Evaluation Clock

Federal law requires a state's Part C evaluation and initial IFSP meeting to be completed within 45 days of referral, and Maryland holds its local programs to that same clock, which starts the day a referral is made, not whenever paperwork happens to catch up 3. That 45-day window covers the evaluation and the first planning meeting, not necessarily the start date of every specific therapy an IFSP recommends, which can follow its own separate scheduling timeline.

Maryland does not charge participating families a fee to take part in the Infants and Toddlers Program; evaluation, service coordination, and the services an IFSP puts in place are provided without billing the family directly, though the state may seek payment through a family's private insurance with consent. That is a genuinely different policy than a family might encounter moving in from a state that does apply an income-based fee, and it is worth confirming current terms directly with the local program rather than assuming a bill will eventually show up.

The Move to Part B at Age Three

A child's eligibility for the Infants and Toddlers Program ends at age 3, and Maryland's local programs are required to begin transition planning well before that birthday, not scramble to arrange it afterward. Around the child's third birthday, eligibility for school-based special education under Part B is considered separately, through the local school system rather than the county's early intervention program, and the vehicle for services changes from an IFSP to an Individualized Education Program 6.

How an IFSP becomes an IEP is a process with its own eligibility category, its own meeting, and its own team, distinct enough from the Infants and Toddlers process a family has just gotten used to that it deserves its own attention. Every state runs a version of this same federal transition: a family moving from Maryland to early intervention in Tennessee, early intervention in Texas, early intervention in Utah, early intervention in Vermont, or early intervention in Virginia would find the same federal floor administered under a different name, a different local structure, and a different family-cost policy.

Common questions

No. Eligibility runs on either a diagnosed condition with a high probability of causing delay, which autism satisfies, or a documented developmental delay measured against Maryland's own threshold. A family can start the referral process while a separate autism evaluation is still pending or hasn't been scheduled yet.

Yes. Parents, relatives, and child care providers can all refer a child directly to their county's Local Infants and Toddlers Program. A doctor's referral can add useful medical history to the file, but Maryland does not require one before an evaluation can be scheduled.

No. Maryland does not bill participating families directly for evaluation, service coordination, or the services an IFSP puts in place, though the state may seek reimbursement through a family's private insurance with consent. It's worth confirming the current cost policy directly with the local program, since these rules can change.

Maryland runs the Infants and Toddlers Program through 24 separate local programs, one per county plus Baltimore City, each handling its own intake and staffing under statewide MSDE policy. Eligibility rules are the same everywhere in the state, but day-to-day staffing, caseloads, and local contacts can differ from one jurisdiction to the next.

Infants and Toddlers Program eligibility ends at 3, and transition planning is required to start well before that birthday. The family and local school system then work through eligibility for Part B special education, which runs on an Individualized Education Program rather than an IFSP, so both the paperwork and the team change even if the child stays eligible.

When a developmental concern needs faster attention

  • —Loss of words, gestures, or social skills a child previously had, at any age
  • —No response to their name by 12 months, or no pointing or waving by 12 months
  • —No back-and-forth smiling or shared enjoyment with a caregiver by 6 months
  • —A significant new feeding, sleep, or seizure-like event alongside the developmental concern
