Mississippi Early Intervention: IFSP to IEP Transition (Part C to Part B)

Your child is enrolled in Mississippi's early intervention program and receiving services. Then someone mentions "the transition" — and suddenly there's talk of meetings, eligibility determinations, and a completely different set of documents. Many parents don't realize until the transition is already happening that the services their child receives at age two are governed by an entirely different federal program than the services they'll receive at age three.

Understanding the Part C to Part B transition in Mississippi — and getting ahead of the process — is one of the most consequential things you can do for your child's long-term educational outcomes.

Two Programs, Two Sets of Rules

IDEA Part C — Early Intervention (Birth to Age 3) Mississippi's Part C early intervention program is called First Steps, administered by the Mississippi State Department of Health (MSDH). First Steps serves infants and toddlers from birth through 34.5 months who have a developmental delay or a condition likely to result in a developmental delay.

Services under Part C are documented in an Individualized Family Service Plan (IFSP). The IFSP is family-centered — it identifies outcomes for both the child and the family, and services are typically delivered in the child's "natural environment" (usually the home or a community setting like childcare). The IFSP is reviewed every six months and rewritten annually.

IDEA Part B — School-Based Special Education (Age 3 and Up) Once a child turns three, responsibility shifts from MSDH First Steps to the local school district. The child's educational program is now governed by an Individualized Education Program (IEP), administered under Mississippi State Board Policy 74.19.

The IEP is child-centered (not family-centered), more formally structured, governed by strict timelines, and tied to educational performance in relation to grade-level standards. Services are delivered in school settings, not the family home.

The shift is significant. The IFSP's family-support orientation gives way to a more legally procedural framework — one with harder deadlines, more documentation requirements, and different eligibility criteria.

The Transition Timeline: What Has to Happen and When

Mississippi follows federal IDEA transition timelines for Part C to Part B. Here is what must happen before your child's third birthday:

At least 90 days before the child's third birthday: The First Steps service coordinator must convene a transition conference. This meeting must include the family and, with parental consent, a representative from the local school district. The purpose is to discuss options for services after the child exits Part C — whether through the public school district's Part B special education program or other community resources.

At least 60 days before the third birthday: The school district must receive a referral if the family wishes to pursue Part B evaluation and services. The referral typically comes from the First Steps service coordinator.

The 60-calendar-day evaluation clock begins at parental consent: Once the district receives a referral and the parent provides written consent for an initial evaluation, Mississippi's strict 60-calendar-day evaluation timeline begins. The district must complete the full Multidisciplinary Evaluation Team (MET) assessment within 60 calendar days of receiving that signed consent.

Before the third birthday: If the child is found eligible and the family wants services to begin at age three, the IEP must be developed and ready to implement on the child's birthday. This means the evaluation, eligibility determination, and IEP development all need to be completed before that date.

This timeline is tight. The failure to plan ahead — which is common when families are not told about the process early — means children often experience a gap in services between their third birthday and whenever the district finally gets around to completing the evaluation and IEP.

Eligibility: Being in First Steps Does Not Guarantee Part B Eligibility

This surprises many families. A child who has been receiving services under Part C does not automatically qualify for Part B special education services.

Under IDEA Part C, eligibility can be based on a developmental delay across any domain (cognitive, physical, communication, social/emotional, adaptive) or on a diagnosed condition that has a high probability of resulting in developmental delay. The threshold is relatively broad, and many children with mild delays qualify.

Under IDEA Part B, Mississippi recognizes 13 specific disability categories:

• Autism
• Deaf-Blindness
• Developmental Delay (this category can be used for children ages 3–9 in Mississippi)
• Emotional Disability
• Hearing Impairment
• Intellectual Disability
• Language/Speech Impairment
• Multiple Disabilities
• Orthopedic Impairment
• Other Health Impairment (OHI)
• Specific Learning Disability (SLD)
• Traumatic Brain Injury (TBI)
• Visual Impairment

For young children transitioning from Part C, the Developmental Delay category is the most commonly used eligibility category — it applies to children ages 3 through 9 in Mississippi who exhibit delays in one or more developmental areas but whose specific disability category may not yet be clearly definable.

However, the MET must complete a full evaluation and determine that the child's delay requires specially designed instruction. A child with a mild delay who is progressing well in typical settings may not meet the threshold. This is where many families get caught off guard: their child received services under First Steps for two years but is found ineligible at age three.

If your child is found ineligible: Request a copy of the evaluation report and the Prior Written Notice explaining the district's reasoning. You have the right to request an Independent Educational Evaluation (IEE) if you disagree with the district's findings. You can also contact MSPTI for help understanding the decision.

The IFSP vs. IEP Comparison

The philosophical shift matters. The IFSP frame — "what does this family need to support their child's development" — gives way to "what specially designed instruction does this child need to access the general education curriculum." Parents who expect the IEP to continue the holistic, family-supportive approach of the IFSP are often frustrated by how narrowly educational the IEP framework feels.

Rural Mississippi and the Transition Gap

Over half of Mississippi's population lives in rural areas, and the transition from Part C to Part B is where rural service gaps become acute. Mississippi's special education teacher vacancy rate reached 599 unfilled positions in 2025-2026 — up from 394 the prior year — and MDE has designated special education as a Critical Shortage Subject area.

For rural districts, this means:

• Evaluation timelines may be difficult to meet because the district lacks qualified evaluators
• Related services (speech, OT, PT) may be delivered by itinerant providers who travel between multiple schools
• Teletherapy is increasingly used to fill service gaps

None of these resource constraints excuse noncompliance with the evaluation timeline. The 60-day clock runs regardless of whether the district has staff available. If the district tells you they cannot schedule an evaluation because of staff shortages, document that statement and contact MSPTI or file a state complaint with the MDE Office of Special Education.

What Parents Should Do Right Now

If your child is currently in First Steps and approaching age two:

1. Ask your service coordinator now when the transition conference will be scheduled. Do not wait for them to schedule it — confirm the date.

2. Request a written transition plan that documents the timeline and who is responsible for each step.

3. Provide written consent for the school district evaluation as early as possible — once you provide written consent, the 60-day clock starts, and starting it earlier gives the district more time to complete the evaluation before the third birthday.

4. Attend the transition conference with written questions about eligibility criteria, what the evaluation will cover, and what happens if your child is found ineligible.

5. Document everything. The same documentation discipline that matters for school-age IEPs matters here — keep every IFSP, evaluation, and correspondence in a dated binder.

The Mississippi IEP & 504 Blueprint includes evaluation request templates, IEP development checklists, and district dispute resolution guides that apply from the Part B entry point forward — the tools you'll need once the school district takes over.
