Who benefits most from early childhood education investments?
The strongest evidence shows that disadvantaged children and families gain the most. A 2026 study found that a telephone-based obesity prevention program for children aged 2-4 was far more cost-effective for low-socioeconomic-status (low-SEP) families than for high-SEP families: the cost per quality-adjusted life year (QALY) gained was $6,549 for low-SEP versus $41,462 for high-SEP, and the chance of being cost-effective at a $50,000 threshold was 99.7% versus 49.6% [5]. This means public money spent on low-income families yields dramatically better health outcomes per dollar.
Similarly, a 2025 analysis of 2,261 children across six countries found that integrated early childhood education models (combining care and education) produced a return on investment of 1:6.8, compared to 1:4.2 for separated models [2]. The cognitive development effect was moderate (d=0.32) and social-emotional gains were significant (d=0.28), with Nordic deep-integration models performing best for social-emotional skills [2].
A 2026 synthesis of six decades of data from the Perry Preschool Project, Abecedarian Project, and Head Start confirmed that high-quality early childhood education boosts school readiness, high school completion, and adult earnings, but only when programs are high-quality—custodial care shows little lasting benefit [6].
How much return can we expect, and under what conditions?
The return on investment varies by program type and targeting. Integrated early childhood education models achieve a 1:6.8 return, meaning $6.80 in long-term societal benefits for every $1 spent [2]. This is higher than the 1:4.2 return for separated models [2]. However, these returns depend on program quality: the average quality rating (ECERS-3) for integrated models was 6.1 out of 7, versus 4.7 for separated models [2].
For preventing child maltreatment, a 2024 systematic review of 26 studies found that early childhood education, home visiting, and individualized intensive parenting programs showed promising cost-effectiveness, but group-based parent education had mixed results [3]. The review noted that most studies were in high-income countries, so results may not apply elsewhere [3].
A 2021 study on home visiting found that using clinical screening (e.g., parenting readiness, home safety) to select families was far more accurate than demographic screening (e.g., Medicaid status, teen parent) for predicting child maltreatment (hazard ratio 4.01, sensitivity 70%) [1]. This means better targeting can improve return on investment by avoiding waste on low-risk families and reaching those who need help most [1].
Do these investments also help the broader economy?
Yes, public investment in early childhood education and care (ECEC) boosts parental employment, especially for mothers. A 2025 study of 26 European countries over 17 years found that higher public ECEC spending helped mothers return to pre-childbirth employment levels within two years, while lower spending led to prolonged employment gaps [4]. This effect held across skill levels and welfare regimes, with low-skilled mothers in Nordic countries benefiting most [4].
This employment boost translates into higher tax revenues and reduced welfare costs, adding to the direct benefits for children. The same study showed that at above-average spending levels, women's employment fully recovered within two years of childbirth, whereas recovery was limited where ECEC investment was lower [4].

Maximizing the return on investment in Early Childhood Home Visiting through enhanced eligibility screening
Clinical screening (e.g., parenting readiness, home safety) predicted child maltreatment with 70% sensitivity and a hazard ratio of 4.01, far outperforming demographic screening, suggesting better targeting improves return on investment in home visiting programs.
