Early Childhood Education
Interventions Addressing the Social Determinants of Health
Early childhood is an important time to promote healthy development,[1,2] and early childhood education (ECE) programs are community-level interventions that are proven and effective. Learn more about how implementing evidence-based ECE programs can benefit children, families, and communities.
What is early childhood education?

This page focuses on the subset of early childhood education (ECE) intervention programs that aim to improve learning, behavior, and social development of children, most commonly focusing on children ages 3 or 4 years.[3,4] ECE interventions can improve child development and act as a protective factor against the future onset of adult disease and disability. ECE programs often aim to increase enrollment among children who are educationally underserved and experience health disparities. Therefore, ECE programs may help increase health equity. Healthy People 2030 says that increasing the percent of children who are enrolled in ECE is a high-priority issue, because ECE programs can help support child development and children’s health outcomes.
This evidence review included ECE programs that addressed one or more of the following: reading and math skills, development of thinking and learning, social and emotional development, and motor skills. Some programs “may offer additional components, including recreation, meals, health care, parental supports, and social services.” ECE programs may be delivered in a variety of ways and settings. ECE programs that are funded by states or district programs may be universal, which means they are available to all children regardless of income.[7,8] Other programs, including federally funded Head Start and evidence-based model programs, such as the Abecedarian and Perry Preschool programs, are provided specifically for children in families with low income.[3,9,10] The Child-Parent Center program is another example of a widely implemented model program; it expanded into 33 sites in Minnesota, Wisconsin and Illinois through a University of Minnesota project funded by the U.S. Department of Education.
What is the public health issue?
Childhood development is an important determinant of health over a person’s lifetime. Early developmental opportunities can provide a foundation for children’s academic success, health, and general well-being. Preschool-aged children’s brains grow very quickly and are about 90 percent of the size of an adult’s brain by age 6. This growth allows children to develop functional skills related to moving their bodies, understanding the world, problem solving, communicating with others, and regulating their emotions and behavior.[13,14] Experiences during early childhood affect connections within the brain that determine a child’s functional development.
Positive experiences support children’s healthy development, and conversely, adverse experiences can hinder it.[15,16] Additionally, adverse early childhood experiences can have biological effects that are strongly associated with numerous adult diseases, including coronary artery disease, chronic pulmonary disease, and cancer.[15,16]
Children in low-income families often are exposed to more adverse early childhood experiences and environmental factors that delay or negatively affect their development and place them at a disadvantage for healthy growth and school readiness.[1,2,17,18] In the United States, 11.6 million children (16.1%) lived in poverty in 2020. ECE programs may not be reaching the children who might benefit most. In 2019, over half (54%) of low-income preschoolers in the United States did not attend any program that provided early childhood education. Eighty-five percent of low-income children who are eligible for childcare subsidies according to federal rules did not receive childcare subsidies in 2018.
What is the evidence of health impact?
Early childhood education interventions can improve children’s development and act as a protective factor against the future onset of adult disease and disability. ECE can counteract the disadvantage some children experience, improve their social and cognitive development, and provide them with an opportunity to achieve school readiness, and lifelong employment, income, and health.[2,3] Systematic reviews of studies examining the effects of ECE programs, found that they were associated with improved:
- Academic achievement.[3,22]
- Cognitive development.[3,22-24]
- Self-regulation skills.[3,22]
- Social-emotional development.[3,22]
ECE benefit estimates, both short- and long-term, included some or all of the following major components[3,22]:
- Increases in maternal employment and income.
- Reductions in crime, welfare dependency, and child abuse and neglect.
- Improvement in health outcomes associated with education.
- Increases in high school graduation rates.
- Better jobs and higher earnings throughout employment years for children participating in these programs.[3,22]
Additional studies have found that ECE is associated with other positive health effects, including healthier weight (such as fewer underweight, overweight, and obese children).
What is the evidence of cost effectiveness?
A systematic review found that the economic benefits exceed costs for different types of ECE programs. Based on earnings gains alone, the benefit-to-cost ratios ranged from
- 3.06:1 to 5.90:1 for State and District programs
- 1.58:1 to 2.51:1 for Federal Head Start programs
- 1.76:1 to 4.39:1 for model programs
The rate of return on investment was much higher when all benefit components including earnings gains were considered. For model programs, based on total benefits, the return on every dollar invested was:
- $2.49 for the Abecedarian program
- $8.60 for the Perry Preschool
- $10.83 for Chicago Child-Parent Center
ECE benefit estimates, both short- and long-term, included some or all of the following major components.[3,22]
- Savings from reduced grade retention.
- Savings in healthcare costs.
- Savings in remedial education and childcare costs.[3,22]
What indicators lead to better quality and better outcomes for ECE?
ECE programs that receive federal or state funding generally need to be licensed. Minimum health and safety standards are set forth through national and state licensing requirements. The Administration on Children and Families sets the performance standards for Head Start early childhood programs for families with low income.
Assessing and strengthening the quality of ECEs may be valuable for two reasons: First, a large percentage of young children are enrolled in ECE, and thus have the potential to be impacted by the quality of the program. Second, policies to support ECE may be used as policy levers to increase equity.[3,31] Specifically, there may be a need for indicators to help assess whether attempts to strengthen ECE meaningfully improve children’s outcomes.
As discussed in a review article by Soliday Hong et al., there are two types of factors associated with better quality of care and better child outcomes: structural factors and process factors. Structural factors include factors such as lower adult-to-child ratios and use of a curriculum (for example, using a defined curriculum where teachers are trained in using the curriculum). Studies show that fewer children per adult in the classroom is linked to stronger child social skills. Studies also show that better curriculum quality is associated with stronger child social skills. Process factors include factors such as additional training for teachers on curriculum and instruction and better emotional support for children. Studies show that additional training for teachers on curriculum and instruction was positively associated with better language and reading outcomes for children. Studies also show that the more emotionally responsive the teacher was, the better the children’s outcomes related to learning to read.
To help measure and track the quality of ECEs, most states and some localities have developed or are developing local standards known as Quality Rating and Improvement Systems (QRIS). As of 2021, 42 states have implemented QRIS systems.
This overview may help inform state, local, and tribal communities about ECE programs and how they can be implemented to improve children’s health outcomes in their communities. This information about the specific interventions that are proven, effective, and make a difference in communities may be helpful in conversation with interested partners when making decisions (e.g., which intervention to include in master planning efforts).
