Which statement best describes the relationship between IDEA and ECI?

Answer: C — IDEA provides the framework that supports ECI services

IDEA creates the system that makes early intervention possible, and ECI is the way states deliver those services to children birth through age 3 and their families under that system. IDEA Part C sets up how children are evaluated, eligible, and given an Individualized Family Service Plan with coordinated services, so ECI programs operate within this federal framework to provide supports like speech, OT, and developmental services. It’s not about prohibition or isolation, and it isn’t only privately funded—the funding and standards come from IDEA and state implementation, guiding how ECI is offered.
