Early Childhood Education

What is early childhood education?

Early childhood education (ECE) aims to improve the cognitive and social development of children ages 3 or 4 years.^{[1, 2]} ECE interventions can improve all children’s development and act as a protective factor against the future onset of adult disease and disability.^[3] Children disadvantaged by poverty may experience an even greater benefit because ECE programs also seek to prevent or minimize gaps in school readiness between low-income and more economically advantaged children.^[4]

All ECE programs must addresses one or more of the following: literacy, numeracy, cognitive development, socio-emotional development, and motor skills.^[4] Some programs may offer additional components, including recreation, meals, health care, parental supports, and social services.^[4] ECE programs may be delivered in a variety of ways and settings. State and district programs may be available to all children regardless of income.^[5] For example, Georgia and Oklahoma have implemented universal preschool programs for all 4-year-olds.^[6] Other programs, including federally funded Head Start and evidence-based model programs, such as the Abecedarian and Perry Preschool programs, are provided specifically for low-income and at-risk children.^{[2, 7, 8]} 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.^[9]

What is the public health issue?

Childhood development is an important determinant of health over a person’s lifetime.^[3] Early developmental opportunities can provide a foundation for children’s academic success, health, and general well-being.^[10] Preschool-aged children experience profound biological brain development and achieve 90 percent of their adult brain volume by age 6.^[11] This physiological growth allows children to develop functional skills related to information processing, comprehension, language, emotional regulation, and motor skills. ^{[11, 12]} Experiences during early childhood affect the structural development of the brain and the neurobiological pathways that determine a child’s functional development.^[13]

Positive experiences support children’s cognitive, social, emotional, and physical development, and conversely, adverse experiences can hinder it.^{[13, 14]} Additionally, strong associations have been found between the biological effects of adverse early childhood experiences and numerous adult diseases, including coronary artery disease, chronic pulmonary disease, and cancer.^{[13, 14]}

Children in low-income families often are exposed to more adverse early childhood experiences and environmental factors that delay or compromise their development and place them at a disadvantage for healthy growth and school readiness.^{[3, 15, 16]} In the United States, 15.5 million children (21%) lived in families with incomes below 100% Federal Poverty Level in 2010.^[17] Also in 2010, less than half of children in families in the lowest income quartile were enrolled in center-based early childhood education programs.^[18]

What is the evidence of health impact and cost effectiveness?

Early childhood education interventions can improve children’s development and act as a protective factor against the future onset of adult disease and disability.^[3] ECE can counteract the disadvantage some children experience, improve their social and cognitive development, and provide them with an equal 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 cognitive development^{[2, 19, 20]}
• Improved emotional development^[2]
• Improved self-regulation^[2]
• Improved academic achievement^[2]

Additional longer-term benefits included:

• Reduction in teen birth rates^[2]
• Reduction in crime rates^[2]

Additional studies have found that ECE is associated with other positive health effects, including healthier weight (such as fewer underweight, overweight, and obese children)^[21] and reduced child maltreatment^[22].

Cost analyses of different types of ECE found that they are associated with positive benefits-to-cost ratios.^[2] Benefit-cost analyses conducted by the Washington State Institute for Public Policy resulted in the following benefit-to-cost ratio estimates: ^[23]

• State and district early childhood education programs: $5.19:1 ^[24]
• Head Start: Benefits to cost ratio $3.09:1. ^[25]

A review of additional analyses examining the benefit-cost ratios of model ECE programs found that they too were associated with positive benefit-to-cost ratios:

• Child-Parent Centers: $5:1 ^[26]
• Perry Preschool: $5:1 ^[26]
• Abecedarian Project: $3:1. ^[26]

ECE benefit estimates, both short- and long-term, included some or all of the following major components:

• Increases in maternal employment and income^[2]
• Reductions in crime, welfare dependency, and child abuse and neglect^{[2, 27]}
• Savings in remedial education and child care costs^[2]
• Improvement in health outcomes associated with education^[2]
• Earnings gains associated with high school graduation^{[2, 27]}
