Nearly 3.2% of US infants and toddlers ages 0 to 3 received early intervention services under IDEA Part C in 2022, totaling about 293,000 children. The data also shows a persistent access gap, with 1 in 4 children who were identified delays not receiving services in 2022 due to waitlists. Early support can measurably reduce later needs, including a 42% lower requirement for special education by kindergarten for children served before age 3.
Key Takeaways
- 37% of US children under 3 have developmental concerns, per CDC 2022 survey.
- Early intervention saved states an average of $12,000 per child in special education costs over lifetime.
- A longitudinal study found that children receiving early intervention services before age 3 had a 42% reduction in the need for special education services by kindergarten compared to those who did not receive services.
- In 2022, 3.2% of infants and toddlers aged 0-3 years in the US received early intervention services under IDEA Part C, totaling approximately 293,000 children.
