Quick answer: Early intervention services are supports for babies and toddlers from birth to age 3 with developmental delays or disabilities, provided under Part C of IDEA. Parents can usually refer their own child. The screening, evaluation, assessments and first IFSP meeting must be completed within 45 days of referral. Services such as speech therapy are written into an Individualized Family Service Plan (IFSP), are delivered in natural settings like the home, and the IFSP is reviewed every six months.
In this guide
Many parents never hear about early intervention until a friend mentions it. Yet it is one of the most powerful supports for toddlers who talk late. Early intervention services focus on coaching parents, because toddlers learn most during daily routines with the people they love.
What Are Early Intervention Services?
| Question | Answer |
|---|---|
| Who is eligible? | Children birth to 3 with a developmental delay or diagnosed condition, as defined by each state |
| Which law? | IDEA Part C |

Step-by-Step Process
From referral to services in 45 days
Under 34 CFR 303.310, screening, evaluation, assessments and the initial IFSP meeting must be completed within 45 days from the date the program receives the referral (CPIR; IDEA 303.342).
The IFSP
- Your child’s current development in all areas.
- Family resources, priorities and concerns, with your agreement.
- Measurable outcomes for your child and family.
- Services, how often, where and who provides them.
- A service coordinator.
- Transition steps toward age 3.
The IFSP is reviewed every six months and evaluated each year, and services start after your written consent (CPIR).
Referral call script
“Hello, I am calling to refer my son, age 21 months, for an early intervention evaluation. He says very few words and I am concerned about his speech. What are the next steps and when will the 45-day timeline start?”

Real-Life Example
Case story
Maria called her state program when her daughter Lina, 19 months, said only two words. An evaluation found a 30% delay in expressive language. The IFSP included weekly home visits from a speech therapist who coached Maria during snack and bath time. Six months later, Lina used more than 80 words.
