Early Intervention SLP: IFSP, Coaching, and the Birth-to-Three Caseload

Early intervention serves children from birth to age three under IDEA Part C. It is the setting least like the rest of the profession: you coach caregivers in their homes, you write an IFSP rather than an IEP, and the family — not the child — is the unit of service.

Part C vs. Part B in one table's worth of rules

• Part C (birth–3): IFSP, family-centered outcomes, natural environments, service coordinator, often a sliding fee scale; eligibility based on developmental delay or established condition, with criteria set by each state.
• Part B (3–21): IEP, educationally relevant goals, least restrictive environment, free appropriate public education at no cost to families.
• Transition at age three must be planned in advance, with a conference before the third birthday.

Praxis items love this contrast — IFSP vs. IEP, natural environment vs. LRE, family outcomes vs. educational goals.

Coaching, not pull-out therapy

Evidence supports caregiver-implemented intervention: the adult who is present all week produces more change than an hour of clinician-directed play. Sessions typically follow a coaching cycle — joint plan, observe the caregiver, model briefly, hand the routine back, reflect, plan the week. Strategies are embedded in routines the family already has: meals, bath, dressing, book sharing, car rides.

Core clinical content

• Prelinguistic skills: joint attention, gestures, turn-taking, vocal play.
• Milestones and red flags — anchor to the developmental milestone chart.
• Late talkers vs. language disorder, and when to watch vs. treat.
• Feeding and pediatric dysphagia, including transitions to textures.
• Early AAC — introducing symbols and devices early does not delay speech.
• Autism red flags and the referral pathway; see autism and social communication.

The job itself

Most EI work is contracted per visit or hourly, with mileage, home schedules, and a lot of driving. Some clinicians build full-time caseloads with one agency; others combine EI with a school or private caseload. Documentation is lighter than in medical settings but deadline-driven, and family cancellation rates are higher than in clinic work, which matters when you're paid per visit.

Is it right for you?

Choose EI if you like autonomy, adult teaching, and messy real-life contexts. Avoid it if you want a fixed room, a fixed schedule, and predictable pay. New graduates can complete a clinical fellowship in EI — just confirm supervision logistics in advance using the CF supervision guide.
