TL;DR
Illinois Early Intervention (EI) runs under IDEA Part C and provides speech therapy, occupational therapy, and other services to children birth through age 2 who have a developmental delay or qualifying condition. Services happen in the child's natural environment, usually at home, and families pay on a sliding scale. Call 1-800-323-4769 to start a referral.
Illinois Early Intervention is the state's version of Part C of the Individuals with Disabilities Education Act (IDEA). [1] Congress created Part C in 1986 so states could build systems for infants and toddlers, birth through age 2, who have developmental delays or conditions that put them at risk for delays. Illinois has run its program since 1991.
The Illinois Department of Human Services (IDHS) runs the program at the state level. [2] Local delivery goes through a network of more than 20 Child and Family Connections (CFC) offices spread across the state, each covering a defined region. The CFC office is your entry point: they manage the intake call, coordinate the evaluation, write the Individualized Family Service Plan (IFSP), and assign a service coordinator who stays with your family the whole way. The reasoning behind EI is simple. Early, focused support during the brain's most plastic years produces better long-term outcomes than waiting. The American Academy of Pediatrics states that "early intervention services have been shown to improve children's functional abilities across multiple developmental domains." [3] Decades of longitudinal data back that up, including the 30-year follow-up from the Abecedarian Project.
When your child turns 3, the program hands them off to services under IDEA Part B, meaning your local school district takes over. That handoff, called the transition plan, must begin at least 90 days before the third birthday under Illinois rules. [2]
Who qualifies?
Eligibility runs on two tracks in Illinois. The first is a measured developmental delay: Illinois sets the bar at a delay of 30 percent or more below age-expected performance in one developmental area, or 20 percent or more in two or more areas. [4] The areas are cognitive development, communication, physical development (including vision and hearing), social or emotional development, and adaptive or self-help skills. Evaluators measure these with standardized tools and clinical observation.
The second track is a diagnosed condition with a high probability of causing a delay. Illinois keeps a list of these established conditions, including Down syndrome, cerebral palsy, autism spectrum disorder (when formally diagnosed), and significant hearing or vision loss. [4] A child with an established condition qualifies automatically, no percentage delay required. That matters a lot for families who get an early ASD diagnosis at 18 or 24 months: you don't have to wait for test scores to prove a delay.
Residency in Illinois is required; citizenship is not. Age is the hard cutoff, since the child must be under 3 when services begin. There's no income threshold for eligibility itself, though cost-sharing is income-based (more on that below).
Illinois also has a developmental risk category for children who don't yet show a measurable delay but whose biological or environmental circumstances put them at elevated risk. Eligibility under this category is more discretionary, and not every CFC office applies it the same way. If your child is borderline, ask the evaluator directly whether the risk category applies.
Speech and language eligibility
Speech and language is one of the five developmental areas Illinois evaluates, [4] and it's the most common reason families call. A child who isn't babbling by 12 months, using single words by 16 months, or combining two words by 24 months is showing signs that warrant an evaluation. Those numbers come from the American Speech-Language-Hearing Association's developmental norms and the AAP's surveillance guidance. [3][5]
If the evaluation finds a 30 percent or greater delay in communication alone, the child qualifies for speech-language therapy under the IFSP. If the delay falls between 20 and 29 percent in communication and there's also a delay in one other area (fine motor or social-emotional, say), the child qualifies under the two-domain rule.
Conditions that often lead to EI speech services include autism spectrum disorder (an established condition with automatic eligibility), childhood apraxia of speech, cleft palate or other structural differences, significant hearing loss, feeding and swallowing difficulties that affect oral motor development, and global developmental delay.
For children with autism, EI can introduce augmentative and alternative communication strategies very early. Research published in the Journal of Autism and Developmental Disorders has consistently shown that introducing aac devices before age 3 does not suppress spoken language and often speeds it up. [6] That finding still surprises some families, and even some older providers.
If your child is showing echolalia (repeating words or phrases rather than generating original language), mention it during the intake call. It's common in toddlers with autism and certain language delays, and it can point the team toward the right therapy approach.
Making the referral
The referral process is simpler than most parents expect. Call the statewide EI hotline at 1-800-323-4769. [2] That number routes to your regional CFC office based on your zip code. Your child's pediatrician, childcare provider, or any other professional can also make the referral for you.
Federal law requires the evaluation to be completed within 45 days of a referral, [1] and Illinois follows that timeline. The CFC contacts you to schedule an intake meeting, then arranges a multidisciplinary evaluation team to assess your child across all five developmental domains.
The evaluation itself is free, and no insurance is billed for it. Evaluators come to your home or another natural setting of your choice, since IDEA requires evaluation in environments that reflect where the child actually spends time.
If your child qualifies, the team holds an IFSP meeting within that same 45-day window. The IFSP is a written plan listing what services your child will get, how often, and what the family's goals are. Unlike an IEP, which is a school document focused on academic outcomes, the IFSP centers the whole family. It can include parent coaching, resources for siblings, and goals built around daily routines like mealtimes and bedtime.
If your child doesn't qualify, you have the right to request an independent evaluation. Illinois's procedural safeguards mirror the federal IDEA requirements, and the CFC must give you written notice explaining the decision and your appeal rights.
What it costs
The evaluation and service coordination are free to all families. [2] Therapeutic services run on a sliding-scale fee schedule based on family income and size, which Illinois calls the family cost participation (FCP) system.
Families below 200 percent of the federal poverty level pay nothing for services. Families above that threshold pay a monthly fee that scales with income, capped at a maximum IDHS resets periodically. As of the most recent published fee schedules, the maximum monthly family contribution is around $60 to $70 per month regardless of how many services the child receives, though you should verify the current amount with your CFC since it changes. [2]
EI providers must bill your private health insurance first (if you have it), then Medicaid, and the family FCP applies to any remaining cost. Here's the part families miss: if your insurer applies EI charges to your deductible and that raises your out-of-pocket costs, Illinois has a process to hold families harmless so insurance billing doesn't make things worse for you. Ask your service coordinator directly about this hold-harmless policy.
| Family income relative to federal poverty level | Monthly family cost participation |
|---|---|
| Under 200% FPL | $0 |
| 200-250% FPL | Low monthly fee (typically under $20) |
| 250-300% FPL | Moderate monthly fee |
| Above 300% FPL | Higher monthly fee, capped (~$60-70/mo) |
Note: exact fee brackets get updated by IDHS and may differ from the approximations above. Confirm with your CFC office.
The bottom line is that almost no family in Illinois pays the full commercial cost of speech therapy through EI. A 45-minute session of private speech therapy in Illinois runs $150 to $250, but EI families rarely pay more than a few hundred dollars per year total.
What services can a child receive through Illinois Early Intervention?
IDEA Part C lays out a list of early intervention services states must offer, [1] and Illinois covers all of them. Speech-language pathology is the one families run into most, followed by occupational therapy, physical therapy, and developmental therapy (sometimes called special instruction). Illinois also provides audiology, nutrition services, social work, vision services, assistive technology (including AAC devices), family training and counseling, and service coordination, which every family gets automatically.
Federal rules require that services happen in the child's natural environment. [1] For most toddlers that's home, but it might also be daycare, a grandparent's house, or the park. Therapy is supposed to happen where the child actually lives their life, not in a clinic waiting room.
How often a child is seen gets decided in the IFSP based on individual need, not a fixed statewide formula. A child with a significant speech delay might get two 45-minute sessions a week; a child with a mild delay in two areas might get one session every other week. The team decides together, and parents sit on that team as equal members with the right to push for more if they believe their child needs it.
When a child is showing early signs of autism, EI can pull together several service types at once. [7] A speech-language pathologist and a developmental therapist might co-treat, or the plan might build in parent coaching so caregivers can use naturalistic language strategies throughout the day. That coaching part matters more than it sounds: research published in Pediatrics found that caregiver-mediated interventions produce language gains that outlast the intervention period itself. [8]
How long does early intervention last, and what happens at age 3?
EI runs until a child's third birthday. That's the federal cutoff under IDEA Part C, and Illinois doesn't deviate from it. [1]
The exit from EI isn't sudden. Illinois requires the IFSP team to start transition planning at least 90 days before the child turns 3, [2] and the service coordinator arranges a transition conference that usually includes the family, current providers, and someone from the local school district.
After 3, kids who still need support move into IDEA Part B, run by the local school district. Eligible children ages 3 to 5 get preschool special education, possibly including speech-language therapy, through an Individualized Education Program instead of an IFSP. Services stay free, but the whole framework shifts: the IEP is built around educational goals, and the school district, not IDHS, calls the shots.
Some families find this jump bumpy because the IFSP model is more family-centered than a school IEP. The amount of service can shrink too. A child getting speech therapy twice a week at home through EI might be offered once a week in a small group at school. If that feels like too little, you can ask for more at the IEP meeting, and you're allowed to bring an advocate with you.
If you're trying to plan ahead of that birthday, it helps to look at how early intervention works more broadly and get a sense of the speech therapy options available once your child ages out.
How does the evaluation work?
Evaluations are multidisciplinary: at least two specialists assess the child across the five developmental domains. [1] In practice, Illinois typically sends a team that might include a speech-language pathologist, a developmental therapist, and sometimes an occupational therapist, depending on what the intake call suggests.
Evaluators lean on standardized tools such as the Battelle Developmental Inventory (BDI-3), the Bayley Scales of Infant and Toddler Development (Bayley-4), and the Communication and Symbolic Behavior Scales (CSBS). The percentage-delay thresholds (30% in one area, 20% in two) come from these scores.
But the scores don't decide everything on their own. Evaluators also rely on structured observation and clinical judgment. A child who scores just above the cutoff on paper but clearly struggles to communicate functionally in real settings can still qualify if the team documents it. It's worth asking evaluators to watch your child during a natural activity rather than only structured table tasks, since toddlers often behave differently in each.
Parent report matters here too. Tools like the MacArthur-Bates Communicative Development Inventories (CDIs) use what parents report about vocabulary and gesture to round out the direct testing. You know your child better than anyone else in that room, and your read on them carries real weight.
If the first evaluation doesn't lead to eligibility and you're still concerned, you can ask for a new one in 6 months, or sooner if you have evidence something has changed. You also have the right to an independent evaluation if you disagree with the team's conclusions.
What if my child is on a waitlist or there's a provider shortage?
Provider shortages in Illinois EI are real, and they've gotten worse since the COVID-19 pandemic.
Illinois has documented gaps in EI providers, especially speech-language pathologists, in rural areas and some suburbs; the Illinois Early Intervention Clearinghouse and advocacy groups have raised this publicly. [9] Federal law says services must start within 30 days of the signed IFSP, but that assumes someone is available to provide them. When no one is, families can end up waiting weeks or months.
If you land on a waitlist, ask your service coordinator to document the gap in writing and keep a copy for yourself. Ask whether providers in nearby regions are accepting new clients, since some families end up traveling for sessions. Ask whether a different service, like developmental therapy, can start while you wait for an SLP opening. And look into online speech therapy as a bridge: Illinois EI allows telehealth for some services under updated post-2020 guidance, though the policy details keep shifting, so check with your CFC directly.
While you wait, parent coaching is one of the most evidence-backed things you can do at home. The Hanen Centre's It Takes Two to Talk program has randomized trial support showing that parent-implemented language strategies produce measurable gains in late talkers. [8] Your service coordinator should be able to point you toward training resources even before formal sessions start.
If you want a structured way to keep practicing language-building routines at home between sessions, Little Words (littlewords.ai) is an AI speech companion built for neurodivergent kids and late talkers. It won't replace your SLP, but it can keep things moving on the days you don't have therapy scheduled.
Illinois runs a mid-to-strong Early Intervention program compared to the rest of the country. Every state has to operate a Part C program under IDEA, but the law leaves a lot of room for each one to structure things differently.[1] Illinois doesn't means-test eligibility, it has one central intake line, and every family gets assigned a service coordinator. The sliding-scale cost cap is also lower here than in a lot of states. Where Illinois lags is provider supply in certain regions and the speed of claims reimbursement, which has historically run slow enough to push providers out of the field. The National Early Childhood Technical Assistance Center (NECTAS) tracks this kind of state-level data and publishes annual comparison reports.[10]| Program element | Illinois | National average / common alternative |
|---|---|---|
| Age range | Birth through age 2 (before 3rd birthday) | Same (federal requirement) |
| Eligibility delay threshold | 30% in 1 domain OR 20% in 2+ domains | Varies: some states use 25%, others 50% |
| Family cost participation | Sliding scale, capped ~$60-70/mo | Varies widely; some states charge per visit |
| Natural environment requirement | Yes | Yes (federal requirement) |
| Central intake line | Yes (1-800-323-4769) | Not all states have this |
| Provider telehealth option | Yes (post-2020) | Most states |
Frequently asked questions
How do I refer my child to Illinois Early Intervention?
Call the Illinois EI hotline at 1-800-323-4769. Any adult can make the referral, parents, grandparents, childcare providers, doctors, it doesn't matter who. No diagnosis or physician's order needed. Once you call, your regional Child and Family Connections office reaches out to start intake, and the full evaluation has to happen within 45 days of that referral.
What is the age cutoff for Illinois Early Intervention?
Kids have to be under 3 when services start, meaning they haven't hit their third birthday yet. There's no minimum age: a newborn with a qualifying condition can be referred right at birth. Once a child turns 3, if they still need services, they move to the local school district under IDEA Part B preschool special education.
Does my child need an autism diagnosis to get EI speech services in Illinois?
No. Kids can qualify through the developmental delay track with no formal diagnosis at all. If autism spectrum disorder has already been diagnosed, that counts as an established condition and makes your child automatically eligible, no delay percentage required. Either route works, and a formal ASD diagnosis isn't a prerequisite for starting the referral.
How long does the Illinois Early Intervention evaluation take?
Federal law gives Illinois 45 days from referral to finish the evaluation and hold the initial IFSP meeting. The evaluation itself is usually just one or two visits, an hour or two each, depending on the child's age and how many areas need assessing.
Is Illinois Early Intervention free?
Evaluation and service coordination cost nothing, always. Actual therapy runs on a sliding-scale system: families at or below 200 percent of the federal poverty level pay nothing, and families above that pay a monthly fee capped around $60 to $70, regardless of how many services the child gets. Check with your CFC office for current numbers.
What if my child doesn't qualify for Illinois Early Intervention?
You'll get written notice explaining the decision along with your appeal rights, and you can request an independent evaluation if you disagree. You can also reapply in 6 months if things change. In the meantime, private speech therapy, community developmental programs, and parent-coaching resources are worth looking into, and you can ask your pediatrician for a referral to a developmental pediatrician if you're still concerned.
Can Illinois Early Intervention services be done at home?
Yes, and usually that's the point: federal law requires EI services to happen in the child's natural environment, which for infants and toddlers is typically home. It can also happen at daycare, a relative's house, or anywhere else the child spends regular time. Telehealth is allowed too for some services in Illinois, and that option expanded a lot after 2020.
What is a Child and Family Connections office in Illinois?
Child and Family Connections (CFC) offices are the local doors into the Illinois EI program, with more than 20 of them covering the state by region. The CFC handles intake, assigns a service coordinator, sets up evaluations, and runs the IFSP meetings. That service coordinator becomes your main contact for the whole process.
What happens to my child's services when they turn 3 in Illinois?
Services stop on the third birthday. Illinois requires transition planning to start at least 90 days ahead of that date. If your child still needs help, services shift to IDEA Part B preschool special education through the local school district, with an IEP replacing the IFSP. It's still free through the school, though the format and intensity may look different.
Can I get a second opinion if I disagree with the Illinois EI evaluation results?
Yes. Under IDEA's procedural safeguards, you can request an independent evaluation if you disagree with an eligibility decision, and you also have access to mediation and due process hearings. The CFC has to spell all of this out in the prior written notice given after an evaluation. If any of it's unclear, ask your service coordinator to walk you through it.
What's the difference between Illinois Early Intervention and a preschool special education program?
EI covers birth through age 2 under IDEA Part C and is run by IDHS: it's family-centered, home-based, and built around an IFSP. Preschool special education covers ages 3 to 5 under IDEA Part B and is run by local school districts: it's more school-centered, uses an IEP focused on educational goals, and usually happens in a school or preschool setting. Both are free.
Does Illinois Early Intervention cover speech therapy for a late talker who doesn't have autism?
Yes, autism isn't a requirement. A child who's simply behind on talking can qualify with a 30 percent or greater delay in communication, or a 20 percent delay in communication plus one other area. Plenty of kids in Illinois EI are late talkers with no other diagnosis at all, and speech-language pathology is one of the most common services the program provides.
How do I find my local Child and Family Connections office in Illinois?
Call the statewide hotline at 1-800-323-4769 and it'll route you to your regional CFC based on zip code. You can also check the Illinois Department of Human Services website for a map of CFC regions with direct contact information.
