Young children’s developmental well-being—comprised of multiple domains, including physical health, motor skills, social-emotional functioning, self-regulation, and early language and math skills—is important to their overall well-being. Developmental progress in these domains is shaped by a combination of factors, including the child’s individual characteristics, family environment, access to needed services, and broader community and societal contexts. Together, these influences form a dynamic ecology that can either support or restrict healthy development. In 2022, a national indicator of children’s developmental well-being and school readiness, Healthy and Ready to Learn (HRTL), was introduced in the National Survey of Children’s Health (NSCH). This new measure for young children ages 3–5 provides opportunities to better understand the developmental well-being of young children in the United States and the child, family, and community conditions that contribute to being healthy and ready to learn.
A child’s environment, experiences, and access to health care can play a critical role in supporting their healthy early development. Access to high-quality primary care and adequate health insurance coverage can ensure that children receive preventative services, developmental screening, and timely treatment when needed while also reducing emergency room visits. A medical home—a model of comprehensive, coordinated, patient- and family-centered primary care—is typically defined by five components: having a personal doctor or nurse, having a usual source for sick care, experiencing family-centered care, the ease of getting needed referrals to other care and services, and experiencing effective care coordination. Adequate and continuous health insurance refers to aspects of a child’s insurance coverage, including plans that allow children to see necessary providers, coverage of needed services, and affordable out-of-pocket costs.
Because children with special health care needs (CSHCN) engage with the health care system differently than children without them (non-CSHCN; e.g., more frequent interactions, connecting to more types of providers, greater needs for referrals), and because underlying conditions can independently affect development, we present findings separately for CSHCN and non-CSHCN.
In this brief, we examine how access to a medical home—and to each of the five individual components—and having adequate insurance coverage relate to children’s developmental well-being across the five domains of HRTL. To attempt to isolate the associations between various aspects of health care access and quality and development at age 3, our analyses also account for the social and economic contexts of the child and family.
This brief is part of a series that summarizes evidence on how children’s daily experiences and environments relate to their developmental well-being at age 3, as measured by HRTL. Age 3 is a key transition period between toddlerhood and preschool, making it an important point for understanding the impact of prenatal-to-age-3 investments and identifying strategies to support children’s health and readiness to learn. These analyses focus on malleable factors—i.e., those that can be influenced or changed, and especially those influenced by families, communities, and public policies and programs that may reduce developmental risks and promote positive outcomes.
Key Findings
Access to health care and the quality of that care are associated with developmental well-being among 3-year-olds in the United States. Importantly, these associations differ for children who have—or do not have—special health care needs. When examined jointly with demographic, social, and family characteristics, we found that:
- A child having a medical home (i.e., personal doctor or nurse, usual source for sick care, no difficulty getting referrals, coordinated care, and family-centered care) was associated with higher odds of being “on track” for overall developmental well-being for both children with and without special health care needs. Among children with special health care needs, it was also associated with higher odds of being on track in the Social-Emotional, Self-Regulation, and Physical Health domains.
- Adequate and continuous insurance was associated with higher odds of being on track overall, in Self-Regulation, and in Physical Health among children without special health care needs; however, it was not significantly associated with any outcome among children with special health care needs.
- We also looked at the five individual components of having a medical home: Among children without special health care needs, receiving family-centered care was associated with higher odds of being on track in Social-Emotional development; not needing a referral was associated with higher odds of being on track in Physical Health.
- Among children with special health care needs, receiving family-centered care was associated with higher odds of being on track in Social-Emotional development; not needing a referral was associated with higher odds of being on track in Social-Emotional, Self-Regulation, and Physical Health; and receiving needed care coordination was associated with higher odds of being on track in Self-Regulation.

No single brief and no single set of factors can fully explain children's developmental well-being. Together, these briefs provide a multi-level portrait of the conditions that support, and sometimes undermine, the development of 3-year-olds in the United States.
