Every child from birth to age 3 in the U.S. is entitled under IDEA (IDEA Part C) to support in reaching developmental milestones if they have a developmental delay -- that is, if they are meeting milestones more slowly than expected, or if they have a diagnosed condition that has a high probability of resulting in a delay. Strong support as soon as a developmental delay is identified can have a positive ripple effect that lasts a lifetime. These services are provided not only for a child with a developmental delay, but also for the child's family, ensuring that caregivers have the tools they need to create a healthy, supportive environment for the whole family. Early intervention services set young kids with delays and disabilities and their families on the course for long-term success. Systemic racism in health and education systems and insufficient federal funding for IDEA Part C threaten access to these services. Better data can help measure equity and, ultimately, ensure that families of color gain access to the high-quality early intervention services they deserve. This executive summary briefly defines early intervention services, describes what is known about equity in early intervention, and highlights key components of and opportunities for equity in screening, evaluation, and early intervention services.
