Early Intervention to Preschool Transition for Deaf and Hard of Hearing Children

Your child turns three, and overnight, everything changes. The early intervention team that came to your home — the deaf educator, the speech therapist, the family support coordinator — is replaced by a school district IEP team that may never have worked with a deaf or hard of hearing child. The Part C to Part B transition is where many DHH children lose services they desperately need, because the rules change and no one explains how.

What Actually Changes at Age Three

Under IDEA, early intervention services (Part C) are family-centered, delivered in the child's natural environment (usually home), and documented in an Individualized Family Service Plan (IFSP). Children generally transition to Part B at age three and, if eligible, receive an IEP. A state may offer extended Part C until the child enters kindergarten; parents of eligible children may choose that option. In some states, an IFSP may serve as the IEP by agreement and with informed parental consent.

The differences matter:

Service model: Part C services come to you. Part B services typically require the child to attend a school-based program. For a DHH toddler who's been receiving home visits from a Teacher of the Deaf, this means the child suddenly needs to access language and communication in a classroom with 15 other three-year-olds — a fundamentally different acoustic and social environment.

Eligibility criteria: Part C eligibility is based on developmental delay as defined by the state or a diagnosed physical or mental condition with a high probability of resulting in developmental delay; hearing loss alone qualifies only where state criteria include it. Part B eligibility requires the district to determine both that the child has a disability under one of IDEA's categories AND that the child needs specially designed instruction. This is where districts deny IEPs for DHH children by arguing that the child is "developing normally" thanks to early intervention — essentially punishing successful intervention.

Focus: Part C centers on the family. Part B centers on the child's educational performance. A district can dismiss parent concerns about language access if the child's test scores look adequate, even when the child is losing ground relative to hearing peers.

The Transition Timeline

IDEA requires the transition process to begin at least 90 days before the child's third birthday. In practice, the process should start at least six months before, because evaluation, eligibility determination, and IEP development all take time.

Key steps:

1. Transition planning conference: Your Part C service coordinator should convene a meeting with you and the school district at least 90 days before the child's third birthday. At this meeting, the district is notified of the child's impending transition.
2. Referral and consent for evaluation: The district must evaluate your child under Part B criteria. You must provide written consent before any evaluation occurs.
3. Evaluation: The district conducts its own evaluation — which may differ significantly from the assessments your early intervention team used. For DHH children, insist on evaluation by professionals who are fluent in your child's communication mode and experienced with low-incidence sensory disabilities.
4. Eligibility determination: The team determines whether your child qualifies for an IEP under Part B.
5. IEP development: If eligible, the IEP must be developed and ready to implement by the child's third birthday.

Where DHH Children Lose Services

The most common service losses during transition:

Teacher of the Deaf: Many early intervention programs provide regular home visits from a certified Teacher of the Deaf. School districts — especially rural and suburban ones — may not have a TOD on staff and will try to substitute general special education services. A general special education teacher is not qualified to address the communication and language needs of a DHH child.

Speech-language therapy frequency: Part C IFSPs often provide 2–3 speech therapy sessions per week in the home. School districts commonly offer 30 minutes per week in a group setting — a dramatic reduction that can stall language development right when it matters most.

Family training: Part C explicitly includes family training and parent counseling where appropriate. Under Part B, parent counseling and training is an IDEA related service when the IEP team determines it is needed to help the child benefit from special education (34 CFR §300.34(c)(8)); it is not categorically excluded. Families may still find that their support changes after transition.

Signing environment: A child who was developing ASL through early intervention may be placed in a preschool classroom with no signing peers and no fluent signing staff. IDEA requires the IEP team to consider opportunities for direct communication with peers and professionals in the child's language and communication mode (34 CFR §300.324(a)(2)(iv)). The lack of signing peers may be relevant to whether the child's needs are met, but it does not by itself establish a violation or require a particular placement.

How to Protect Your Child During Transition

Request an extended IFSP: Some states allow families to continue Part C services through the IFSP until the child enters kindergarten, rather than transitioning to Part B at age three. Ask your Part C coordinator whether your state offers this option. The trade-off: IFSP services may be more limited in scope than a full IEP, but they maintain the home-based, family-centered model.

Get your own evaluations before the district's: Have your child's audiologist, speech-language pathologist, and Teacher of the Deaf write current reports documenting the child's communication level, technology needs, and recommended services before the district evaluation. These become your evidence for what the IEP should include.

Bring your Part C team to the IEP meeting: Under IDEA, you can invite anyone with knowledge about your child to the IEP meeting (34 CFR §300.321(a)(6)). Your early intervention TOD and SLP know your child's communication profile better than anyone at the school. Their presence at the first IEP meeting can prevent the "she seems fine" dismissal.

Insist on the required considerations: At the very first IEP meeting, ask how the team is addressing the four DHH-specific factors in 34 CFR §300.324(a)(2)(iv) and assistive technology under §300.324(a)(2)(v). If the proposed IEP is "preschool special education with hearing consultation once a month," ask how that plan addresses your child's individual needs.

Document everything in writing: If the district proposes reducing services that Part C provided, request a prior written notice (34 CFR §300.503) explaining why the reduction is appropriate. The PWN forces the district to justify the change on the record.

The First IEP Should Address

For a DHH child transitioning from early intervention, the first IEP should cover:

• Communication mode and plan (who provides communication access, in what settings)
• Hearing technology management (who checks equipment daily, troubleshooting protocol)
• Language development goals in the child's primary communication mode
• Speech and auditory skill development goals (if appropriate to the child's communication approach)
• Social communication goals — how the child will interact with peers
• Assistive technology — DM system, visual alerting, captioning as appropriate
• Related services — TOD hours, SLP hours, educational audiology
• A transition support plan for the first 90 days, acknowledging that the child is entering a new environment

The Deaf & Hard of Hearing IEP & Communication Access Toolkit includes a Communication Plan Template and IEP Goal Bank designed to bridge the gap between what early intervention provided and what the school district must continue — so your child's third birthday doesn't become the day services disappear.
