IDEA Part C: Free Early Intervention for Infants & Toddlers (Birth-2)

Last updated 5 months ago. Our resources are updated regularly but please keep in mind that links, programs, policies, and contact information do change.

The early years of a child’s life are critical for growth and development. For infants and toddlers facing developmental challenges, early support can make a significant difference in their future.

The Individuals with Disabilities Education Act (IDEA) Part C program is a federal initiative designed to provide vital early intervention services to eligible infants and toddlers with disabilities, from birth through age two, and their families.

This program aims to:

• Enhance child development
• Minimize potential delays
• Reduce future educational costs
• Maximize independent living potential
• Empower families to meet their child’s unique needs

Eligibility Requirements

IDEA Part C is designed to identify infants and toddlers (birth through age two) who have or are likely to experience developmental delays. The federal framework establishes broad categories, but specific criteria differ significantly between states.

Families should always consult their specific state’s early intervention program for precise eligibility details. A database of state definitions is available via the Early Childhood Technical Assistance (ECTA) Center.

Federal law requires states participating in Part C to serve infants and toddlers in at least two main categories:

Developmental Delay

This is a primary way children become eligible for Part C services. Federal regulations require each state to establish its own “rigorous definition” of developmental delay.

This definition must be based on a child experiencing delays in one or more of the following five developmental areas:

• Cognitive Development: Skills related to thinking, learning, memory, and problem-solving
• Physical Development: Includes gross motor skills (like rolling, crawling, walking), fine motor skills (like grasping), and vision and hearing
• Communication Development: Skills related to understanding language (receptive) and using language (expressive), including gestures, sounds, and words
• Social or Emotional Development: Skills related to interacting with others, managing emotions, playing, and forming relationships
• Adaptive Development: Self-help skills necessary for daily living, such as feeding, dressing, and adjusting to new situations

While the federal government outlines these five areas, it grants states considerable flexibility in defining what constitutes a “delay.” States determine the specific level of delay required for eligibility, often expressed as a percentage delay compared to peers or a certain number of standard deviations below the mean on standardized tests.

This flexibility means that a child might qualify for services in one state but not in another. Eligibility determinations also consider the informed clinical opinion of qualified professionals.

Established Conditions

The second mandatory eligibility category includes infants and toddlers who have a diagnosed physical or mental condition with a high probability of resulting in developmental delay. This allows for proactive support even if a significant delay isn’t yet measurable.

Examples of such conditions might include:

• Chromosomal abnormalities (e.g., Down syndrome)
• Genetic or congenital disorders
• Sensory impairments (e.g., blindness, significant hearing loss)
• Inborn errors of metabolism
• Disorders reflecting disturbance of nervous system development
• Congenital infections
• Severe attachment disorders
• Disorders secondary to exposure to toxic substances, including prenatal drug exposure

In cases involving established conditions, existing medical or other records may sometimes be sufficient to determine eligibility without requiring a full developmental evaluation, although an assessment to plan services is still necessary.

At-Risk Infants and Toddlers (State Option)

IDEA also permits, but does not require, states to extend Part C eligibility to infants and toddlers who are considered “at risk” of experiencing substantial developmental delays if they do not receive early intervention services.

This category might include children facing specific biological or environmental risk factors, such as very low birth weight, significant prenatal complications, caregiver substance abuse, homelessness, or confirmed abuse or neglect.

Because this is a state option, availability varies. Families should inquire with their state’s program to see if this category applies.

Available Early Intervention Services

Once a child is determined eligible for IDEA Part C, they and their family can receive early intervention services (EIS) tailored to their unique needs.

Definition and Purpose

Early Intervention Services under IDEA Part C are defined as developmental services provided under public supervision and selected in collaboration with the parents. Their purpose is twofold:

1. To meet the developmental needs of the infant or toddler with a disability (in the five developmental areas: physical, cognitive, communication, social-emotional, and adaptive)
2. To address the family’s needs related to enhancing their child’s development, as identified in the Individualized Family Service Plan (IFSP)

These services must meet state standards and be provided by qualified personnel.

While certain core functions like evaluations, assessments, IFSP development, and service coordination must be provided at no cost to families, states may establish systems of payment for some other early intervention services. This can include using a sliding fee scale based on income or billing public (like Medicaid) or private insurance.

However, families cannot be denied necessary services due to an inability to pay. Parental consent is required before using family insurance benefits.

Because Part C funds are considered the “payer of last resort,” states utilize other funding sources (like insurance or Medicaid) before using federal Part C dollars for direct services.

Range of Services

IDEA Part C authorizes a wide array of services to address the holistic needs of the child and family. The specific services provided are individualized based on the IFSP. This list provides examples, but is not exhaustive:

• Assistive Technology: Devices (e.g., adaptive toys, communication aids) and related services to help a child function
• Audiology Services: Identifying and managing hearing loss, including hearing aid fitting
• Family Training, Counseling, and Home Visits: Supporting families in understanding their child’s needs and promoting development
• Health Services: Services needed for the child to benefit from other EI services (e.g., nursing care during therapy)
• Medical Services: Only for diagnostic or evaluation purposes to determine eligibility
• Nursing Services: Health assessments and provision of nursing care related to the IFSP
• Nutrition Services: Assessment and counseling regarding dietary needs
• Occupational Therapy (OT): Services focused on fine motor skills, sensory processing, feeding, and activities of daily living
• Physical Therapy (PT): Services focused on gross motor skills, movement, balance, and mobility
• Psychological Services: Administering tests, interpreting results, providing counseling
• Service Coordination (Case Management): A mandatory service that assists families in accessing and coordinating all needed services and navigating the EI system
• Sign Language and Cued Language Services: Instruction in sign language or cued language
• Social Work Services: Assessment, counseling, and helping families access community resources
• Special Instruction: Designing learning environments and activities to promote development
• Speech-Language Pathology (SLP) Services: Services addressing communication development and feeding/swallowing issues
• Transportation: Costs associated with enabling the child and family to receive EI services
• Vision Services: Evaluation of visual function and providing related services

Natural Environments

A cornerstone philosophy and legal requirement of IDEA Part C is that early intervention services must be provided in natural environments to the maximum extent appropriate for the child.

Natural environments are defined as settings that are typical for the child’s same-aged peers who do not have disabilities. This most often includes the child’s home and community settings like childcare centers, parks, libraries, playgrounds, and other places the family typically goes.

The emphasis on natural environments stems from the belief that young children learn best through everyday experiences and interactions with familiar people in familiar contexts. The goal is to integrate strategies and supports into the family’s daily routines and activities, building the capacity of parents and caregivers to enhance their child’s learning throughout the day.

If the IFSP team determines that a specific service cannot be effectively provided in a natural environment, the IFSP must include a justification explaining why a different setting is necessary.

Accessing Part C Services: Step-by-Step

Navigating any government program can feel daunting. Fortunately, the process for accessing IDEA Part C early intervention services follows a defined sequence with specific timelines designed to get support to eligible children and families efficiently.

Child Find and Referral

The process begins with identifying children who might need support. Every state is required to have a “Child Find” system actively working to locate, identify, and evaluate infants and toddlers (birth through age two) with disabilities.

A referral can be made by anyone who has concerns about a child’s development – this includes parents, doctors, hospital staff, childcare providers, social workers, or other family members. Parents have the right to refer their own child directly if they have concerns.

Primary referral sources, like physicians or hospitals, are encouraged to make referrals promptly, typically within seven days of identifying a potential need.

To initiate a referral, families can:

• Talk to their child’s pediatrician and ask for a referral
• Contact their state’s early intervention program directly. Contact information can often be found on the state health or education department website, or through national resources like:
  • The ECTA Center’s State Part C Coordinator list
  • The Center for Parent Information and Resources’ “Find Your Parent Center” tool
  • The CDC’s resources for finding state programs
• Call a statewide hotline if available (e.g., Ohio’s 1-800-755-GROW)

When making contact, families should explain their concerns about their child’s development and state they are requesting an evaluation under IDEA Part C.

Service Coordinator Assignment

Once the referral is received by the local early intervention program, a service coordinator will be assigned to the family. This person acts as the family’s primary point of contact throughout the process.

They explain the steps involved, discuss parental rights, help schedule evaluations and assessments, and coordinate the development of the IFSP if the child is found eligible.

Screening (Optional)

Some states utilize an initial screening process as a first step after referral. Screening involves brief procedures to quickly determine if a child is suspected of having a developmental delay and warrants a more comprehensive evaluation.

Parental consent must be obtained before any screening occurs. It’s important for families to know that even if a screening doesn’t indicate a potential problem, they still have the right to request a full evaluation if they remain concerned.

Evaluation

If screening suggests a potential delay, or if the state proceeds directly to evaluation, the next step is a comprehensive, multidisciplinary evaluation. The primary purpose of the evaluation is to determine if the child meets the state’s specific eligibility criteria for IDEA Part C services.

This evaluation looks at all five areas of development (cognitive, physical, communication, social-emotional, adaptive) using various methods, which may include standardized tests, observations, and interviews with the parents.

The evaluation must be conducted by qualified professionals. Parental consent is required before the evaluation can begin. Importantly, the evaluation process itself is provided at no cost to the family.

As noted earlier, if a child has a known established condition with a high probability of delay, a formal developmental evaluation might be bypassed, and eligibility determined based on existing records.

Assessment (Child and Family)

If the evaluation determines the child is eligible for Part C services, the team then conducts assessments to gather detailed information needed for planning the IFSP. This involves:

• Child Assessment: A deeper look at the child’s unique strengths, needs, and current functioning levels across the five developmental areas
• Family Assessment: A voluntary process, directed by the family, to identify their resources, priorities, and concerns related to enhancing their child’s development

Like the evaluation, assessments are provided at no cost to families.

The 45-Day Timeline

IDEA sets a strict deadline for these initial steps. The entire process – from the date the early intervention program receives the referral to the date the initial IFSP meeting is held (including screening, evaluation, and assessments, if applicable) – must be completed within 45 calendar days.

This tight timeline emphasizes the urgency of early intervention. However, it requires efficient coordination among the family, service coordinator, and evaluators. Families should be prepared for a potentially fast-paced process and understand their role in facilitating it.

There are only two federally allowed exceptions to the 45-day timeline:

1. The child or parent is unavailable to complete the required steps due to documented “exceptional family circumstances”
2. The parent has not provided consent for the screening, evaluation, or assessment despite documented, repeated attempts by the program to obtain it

Even if an exception applies, the program must document the reason and complete the process as soon as possible once the circumstance no longer exists.

In some cases where delays occur but eligibility is likely, an “Interim IFSP” might be developed with parental consent to start some needed services while awaiting completion of the full evaluation and assessment process.

The following table summarizes the key steps and timeline:

Understanding the Individualized Family Service Plan (IFSP)

If a child is found eligible for IDEA Part C services, the next critical step is the development of the Individualized Family Service Plan, commonly known as the IFSP.

Purpose and Philosophy

The IFSP is the written document that serves as a roadmap or agreement outlining the specific early intervention services the eligible child and their family will receive.

A core philosophy guides the IFSP: the family is the child’s most important resource, and a young child’s needs are intrinsically linked to the needs and strengths of their family.

Therefore, the IFSP is intentionally family-centered. It’s designed collaboratively with the parents as major contributors, focusing not only on the child’s developmental needs but also on the family’s resources, priorities, and concerns related to enhancing the child’s development.

This family focus distinguishes the IFSP from the Individualized Education Program (IEP) used for school-aged children under Part B of IDEA, which centers primarily on the child’s educational needs.

Families should view the IFSP process as an opportunity to address their own needs for support and information in helping their child thrive. The OSEP Model IFSP Form provides a template illustrating the required components.

Required Components

Federal regulations mandate that every IFSP include specific information:

• Child’s Present Levels of Development: Information on the child’s current functioning in all five developmental areas based on evaluation and assessment results
• Family Information (with parental consent): A statement of the family’s resources, priorities, and concerns related to enhancing the child’s development
• Measurable Results or Outcomes: Specific goals expected to be achieved for the child and family, including pre-literacy and language skills as appropriate
• Specific Early Intervention Services: Details on the services needed to meet the unique needs of the child and family, including the frequency, intensity, method, and anticipated duration of each service
• Natural Environments Statement: Identification of the natural environments where services will be provided. If any service cannot be provided in a natural setting, a justification must be included
• Service Dates: The projected start date for services and their anticipated length or duration
• Service Coordinator: The name of the service coordinator responsible for implementing the IFSP and coordinating with other agencies and individuals
• Transition Plan: For toddlers approaching age three, the IFSP must include the steps and services needed to support a smooth transition out of Part C services
• Payment Arrangements (if applicable): Information on who will pay for the services

The IFSP Team

The IFSP is not created in isolation; it’s developed during a meeting by a multidisciplinary team. Federal regulations specify the required participants for the initial IFSP meeting and subsequent annual review meetings:

• The parent(s) of the child
• Other family members, if requested by the parent and feasible
• An advocate or person outside the family, if the parent requests their participation
• The designated Service Coordinator
• A person (or persons) directly involved in conducting the child’s evaluations and assessments
• As appropriate, persons who will be providing the early intervention services outlined in the IFSP

Parents are key members of this team, and their input, concerns, and priorities are central to the process.

Review and Revision

Because infants and toddlers grow and change rapidly, the IFSP is considered a dynamic document that needs regular updating. IDEA requires that the IFSP be reviewed at least every six months. Additionally, the IFSP must be formally evaluated and revised (if needed) at least once a year.

Reviews can happen more frequently if the child’s or family’s needs change, or if the family requests one. The purpose of these reviews is to assess the child’s progress toward the outcomes identified in the IFSP and to determine if the outcomes themselves or the services being provided need to be modified.

This regular cycle of goal-setting, service delivery, progress monitoring, and plan adjustment provides a framework for accountability and ensures the IFSP remains relevant to the child’s and family’s evolving needs.

Family Rights and Procedural Safeguards

IDEA Part C provides families with specific legal rights, known as procedural safeguards, designed to protect them and their child throughout the early intervention process. These safeguards ensure that families are informed partners in decision-making and have avenues for recourse if disagreements arise.

State lead agencies must provide families with a written explanation of these rights, often called a “Procedural Safeguards Notice”. Families can find detailed information on the regulations at 34 CFR §§303.400–303.449 and helpful summaries from resources like the Parent Center Hub and the ECTA Center.

Key Rights

Families are guaranteed several fundamental rights under IDEA Part C:

Parental Consent

This is a cornerstone right. Families must give their informed written consent before the early intervention system can take certain actions, including:

• Initial screening (if used by the state)
• Initial evaluation and assessments of the child
• Starting the provision of early intervention services listed in the IFSP
• Using the family’s public benefits (e.g., Medicaid) or private insurance to pay for services
• Sharing personally identifiable information (PII) from the child’s records with outside parties (with some exceptions)

“Informed” consent means the parent has been fully informed about the proposed activity in their native language or other mode of communication and agrees in writing.

Parents have the right to consent to some services listed in the IFSP but decline others, without jeopardizing their eligibility for the accepted services. They also have the right to revoke their consent for services at any time after initially giving it.

Prior Written Notice

Families have the right to receive written notice, in their native language or other mode of communication, a reasonable time before the lead agency or an EIS provider proposes to initiate or change—or refuses to initiate or change—the child’s identification, evaluation, placement, or the provision of early intervention services.

This notice ensures parents are informed about upcoming decisions and have an opportunity to respond. The notice must include specific information, such as:

• A description of the action proposed or refused
• The reasons why
• Any evaluation procedures or records used as a basis for the action
• A description of other options considered
• Information about procedural safeguards and how to file a complaint

Access to Records

Parents have the right to inspect and review all early intervention records relating to their child and family. The agency must provide access without unnecessary delay, before any IFSP meeting or due process hearing, and in no case more than 10 days after the parent’s request.

Parents also have the right to request explanations of information in the records and to ask for records to be amended if they believe information is inaccurate, misleading, or violates privacy rights.

Families are entitled to receive copies of evaluations, assessments, and IFSPs, usually at no cost.

Confidentiality

Families have the right to the confidentiality of personally identifiable information (PII) in their child’s early intervention records. IDEA adopts privacy protections similar to the Family Educational Rights and Privacy Act (FERPA).

Generally, parental consent is required before PII can be disclosed to individuals or agencies not directly involved in providing Part C services, unless specific exceptions apply.

Participation

Parents are essential members of the team and have the right to participate in all meetings concerning their child’s identification, evaluation, assessment, IFSP development and review, and placement decisions.

To facilitate meaningful participation, meetings must be scheduled at times and locations convenient for the family and conducted in the family’s native language or other mode of communication, unless clearly not feasible.

The requirement for communication in the family’s native language is crucial for equity but can present logistical challenges for states needing to provide interpreters or translated documents for diverse populations.

Dispute Resolution Options

When families and the early intervention system disagree about identification, evaluation, eligibility, placement, the IFSP, or the provision of services, IDEA Part C provides several mechanisms for resolving these disputes.

Families can learn more from their state lead agency or Parent Center, and resources like the CADRE Family Guides offer detailed explanations.

Mediation

A voluntary process where parents and the agency meet with a qualified, impartial mediator to try and reach a resolution acceptable to both parties. Mediation is provided at no cost to the family. Discussions are confidential.

If an agreement is reached, it’s put into a legally binding written document signed by both parties. Mediation cannot be used to deny or delay a parent’s right to a due process hearing.

It is often seen as a less adversarial way to resolve disagreements and can help preserve relationships.

State Complaint

Anyone (a parent, an organization, an individual from another state) can file a written complaint directly with the state lead agency if they believe that the Part C program or an EIS provider has violated a requirement of federal or state law or regulations.

The complaint must be in writing, state the alleged violation and the facts supporting it, and include signature and contact information. If it concerns a specific child, it must include the child’s name and address. Generally, the violation must have occurred within one year of filing the complaint.

The state lead agency must investigate the allegations and issue a written decision with findings of fact and conclusions within 60 calendar days, unless an extension is necessary due to exceptional circumstances or if the parties agree to try mediation.

The state agency must also ensure corrective action is taken if a violation is found. This process is free for the complainant.

Due Process Complaint and Hearing

This is a more formal, quasi-judicial process initiated by a parent (or sometimes the agency, depending on state rules) to resolve disagreements specifically related to the identification, evaluation, assessment, placement, or provision of appropriate early intervention services for their child.

States have the option to use the due process procedures outlined in Part C of IDEA or adopt the more detailed procedures from Part B (used for school-aged children). Families should check their state’s specific procedures.

The process involves filing a written complaint detailing the issues. A hearing is then conducted by an impartial hearing officer who listens to evidence, examines witnesses, and makes a legally binding decision.

Under Part C rules, the decision is typically due within 30 days of the complaint being received. Parents have specific rights during the hearing, including the right to be accompanied by counsel or advisors, present evidence, cross-examine witnesses, and receive a free transcript and copy of the decision.

“Stay Put” Provision

A significant aspect of due process is the “stay put” right. This generally means that while the due process complaint is being resolved, the child continues to receive the early intervention services currently identified in the IFSP that the parents have consented to, unless the parents and the lead agency agree otherwise.

This prevents disruption of services during the dispute. This right typically applies during due process proceedings, not necessarily during state complaints or mediation alone.

Transitioning Out of Part C: Planning for the Next Steps

Eligibility for IDEA Part C early intervention services typically ends when a child turns three years old. Recognizing that children may still need support, IDEA mandates a structured process to ensure a smooth and effective transition from Part C to the next appropriate setting.

The goal is to prevent gaps in services and support families through this change. Resources on this process are available from the ECTA Center and the Parent Center Hub.

The Transition Plan

Transition planning is not an afterthought; it’s a required component of the IFSP for toddlers approaching age three. Development of this transition plan must begin early, specifically between 9 months and 90 days before the child’s third birthday.

The transition plan, documented within the IFSP, must outline specific steps and services to support the child and family’s move from Part C. Key elements include:

• Discussions with and training for parents regarding potential future placements and related matters
• Procedures to prepare the child for changes in service delivery and help them adjust to a new setting
• Confirmation that the required notification has been sent to the Local Education Agency (LEA – the local school district) and/or State Education Agency (SEA), if the child is potentially eligible for Part B preschool services
• Transmission of relevant documents (like the most recent evaluation and IFSP) to the LEA to ensure service continuity
• Identification of any other transition services or activities deemed necessary by the IFSP team to support a smooth transition

The Transition Conference

IDEA requires the Part C lead agency or EIS provider to convene a transition planning conference.

Timeline: This conference must occur at least 90 days before the child’s third birthday. With the agreement of all parties, it can be held earlier, up to 9 months before the third birthday.

Participants: The conference brings together key parties involved in the transition:

• The family
• Representatives from the Part C program (like the service coordinator)
• Representatives from the LEA (school district) if the child is potentially eligible for Part B preschool special education services

If the child is not likely eligible for Part B, the Part C agency should invite representatives from other relevant community programs or services that might support the child and family after age three.

Purpose: The conference is a crucial forum for collaboration. Its purposes include:

• Discussing potential program options available after age three
• Reviewing the steps outlined in the IFSP transition plan
• Establishing timelines for completing transition activities
• Explaining the Part B eligibility determination process if applicable
• Ensuring coordination between the Part C and receiving programs

Notification to Education Agencies (LEA/SEA)

To facilitate the transition to potential school-based services, the Part C system has a specific notification requirement. For every toddler receiving Part C services who is considered potentially eligible for Part B preschool special education, the Part C lead agency must notify both the State Education Agency (SEA) and the LEA where the child resides.

This notification acts as a referral to the school system and must occur at least 90 days before the child’s third birthday (unless the child was referred to Part C very close to age three, in which case specific timelines apply).

The notification typically includes the child’s name, date of birth, and parent contact information. Sharing more detailed information, like evaluation reports or the IFSP, generally requires parental consent, unless state law or interagency agreements permit sharing without separate consent.

Some states have policies allowing parents to “opt-out” of this automatic notification to the LEA/SEA.

Potential Next Steps After Part C

As a child exits Part C around their third birthday, several pathways are possible, depending on their needs and eligibility for other programs:

Transition to IDEA Part B Preschool Special Education: If the LEA, after conducting its own evaluation, determines the child is eligible for special education and related services under Part B criteria, an Individualized Education Program (IEP) will be developed.

It is important to note that Part B eligibility criteria differ from Part C. Part B focuses on whether the child meets the definition of one of IDEA’s disability categories and requires special education to benefit from the educational program.

A child eligible for Part C based on developmental delay might not automatically qualify for Part B. If found eligible, the goal is for the IEP to be developed and implemented by the child’s third birthday, allowing services to begin promptly.

Transition to Other Community Programs: If a child is found not eligible for Part B services, or if the family chooses not to pursue Part B, the transition plan developed in the IFSP should help connect the family with other appropriate community-based programs or services.

These might include Head Start, public or private preschools, childcare programs, or community health services.

Extended Part C Services (State Option): IDEA allows states the option (under Section 635(c)) to permit children who are eligible for Part B preschool services to continue receiving services under Part C (through their IFSP) beyond age three, up until they are eligible to enter kindergarten.

If a state offers this option, families can choose whether to transition to Part B at age three or remain in the Part C system. This option is not available in all states; families must check their state’s policies.

The structured transition process, involving early planning, interagency collaboration, and clear communication with families, is designed to support children and families effectively as they move beyond the Part C early intervention system.
