In supporting children's development, countries invest in the future successes of economies and societies. Awareness of the critical role early childhood education and care (ECEC) plays in setting a strong foundation for children's learning, development and well-being has grown among policy makers worldwide. The OECD Quality beyond Regulations policy review provides countries with an overview of the different dimensions of quality in ECEC. It also highlights policies that can enhance process quality in particular. From this review, emerged the present report, taking an in-depth look at Luxembourg's ECEC system. It outlines the system's main strengths and challenges, focusing on workforce development and quality assurance through the monitoring system. The report provides tailored policy recommendations to improve provision in line with national goals.

That prenatal events can have life-long consequences is now well established. Nevertheless, research on the fetal origins hypothesis is flourishing and has expanded to include the early childhood (postnatal) environment. Why does this literature have a “second act?” We summarize the major themes and contributions driving the empirical literature since our 2011 reviews, and try to interpret the literature in light of an overarching conceptual framework about how human capital is produced early in life. One major finding is that relatively mild shocks in early life can have substantial negative impacts, but that the effects are often heterogeneous reflecting differences in child endowments, budget constraints, and production technologies. Moreover, shocks, investments, and interventions can interact in complex ways that are only beginning to be understood. Many advances in our knowledge are due to increasing accessibility of comprehensive administrative data that allow events in early life to be linked to long-term outcomes. Yet, we still know relatively little about the interval between, and thus about whether it would be feasible to identify and intervene with affected individuals at some point between early life and adulthood. We do know enough, however, to be able to identify some interventions that hold promise for improving child outcomes in early life and throughout the life course.

We examine the channels through which a randomized early childhood intervention in Colombia led to significant gains in cognitive and socio-emotional skills among a sample of disadvantaged children aged 12 to 24 months at baseline. We estimate the determinants of parents’ material and time investments in these children and evaluate the impact of the treatment on such investments. We then estimate the production functions for cognitive and socio-emotional skills. The effects of the program can be explained by increases in parental investments, emphasizing the importance of parenting interventions at an early age.

We examine heterogeneous treatment effects of a universal child care program in Germany by exploiting variation in attendance caused by a reform that led to a large expansion staggered across municipalities. Drawing on novel administrative data from the full population of compulsory school entry examinations, we find that children with lower (observed and unobserved) gains are more likely to select into child care than children with higher gains. Children from disadvantaged backgrounds are less likely to attend child care than children from advantaged backgrounds but have larger treatment effects because of their worse outcome when not enrolled in child care.

How much of the income-based gaps in cognitive ability and academic achievement could be closed by a two-year, center-based early childhood education intervention? Data from the Infant Health and Development Program (IHDP), which randomly assigned treatment to low-birth-weight children from both higher- and low-income families between ages one and three, shows much larger impacts among low-than higher-income children. Projecting IHDP impacts to the U.S. population's IQ and achievement trajectories suggests that such a program offered to low-income children would essentially eliminate the income-based gap at age three and between a third and three-quarters of the age five and age eight gaps.How much of the income-based gaps in cognitive ability and academic achievement could be closed by a two-year, center-based early childhood education intervention?

This report discusses policies and practices that shape quality and equity in early childhood education and care. It examines how the work environment, including the educational background of staff, and the policies that shape teaching approaches affect the quality of the education provided to our youngest learners. The book concludes with an overview of current thinking about how young children use, and are affected by, information and communication technologies (ICT). Linking the way children interact with ICT inside of school to the way they already use it outside of school could be the key to unlocking technology’s potential for learning. Children learn at a faster rate during the first five years of their life than at any other time, developing cognitive, and social and emotional skills that are fundamental to their future achievements and well-being throughout childhood and as adults. Despite compelling evidence that high quality early childhood education and care programmes can make a crucial difference to children’s progress through school and success in adult life, large differences in access to and the quality of these programmes persist within and across countries.

This paper evaluates the long-run effects of Head Start using large-scale, restricted administrative data. Using the county rollout of Head Start between 1965 and 1980 and age-eligibility cutoffs for school entry, we find that Head Start generated large increases in adult human capital and economic self-sufficiency, including a 0.65-year increase in schooling, a 2.7 percent increase in high school completion, an 8.5 percent increase in college enrollment, and a 39 percent increase in college completion. These estimates imply sizable, long-term returns to investments in means-tested, public preschool programs.

We use data from the Head Start Impact Study (HSIS) to evaluate the cost-effectiveness of Head Start, the largest early childhood education program in the United States. Head Start draws roughly a third of its participants from competing preschool programs, many of which receive public funds. We show that accounting for the fiscal impacts of such program substitution pushes estimates of Head Start’s benefit-cost ratio well above one under a wide range of assumptions on the structure of the market for preschool services and the dollar value of test score gains. To parse the program’s test score impacts relative to home care and competing preschools, we selection-correct test scores in each care environment using excluded interactions between experimental assignments and household characteristics. We find that Head Start generates larger test score gains for children who would not otherwise attend preschool and for children who are less likely to participate in the program.

Governments worldwide have reformed early childhood education (ECE) to equip young people with competitive skills for an increasingly specialized workforce. These reforms have coincided with a widespread acceptance of meritocratic beliefs holding that talent and effort, rather than uncontrollable factors (e.g., luck, social context), determine individuals’ lifetime success and achievement. This study examines whether recent ECE reforms may have promoted an economic meritocratic mindset that favors skills linked to individual competition for future achievement. Data came from a total of 92 documents published between 1999 and 2023, including ECE advisory reports from international organizations and government-endorsed ECE curricula from 53 countries across Africa, the Americas, Asia, Europe, and Oceania.

A growing literature establishes that high quality early childhood interventions targeted toward disadvantaged children have substantial impacts on later life outcomes. Little is known about the mechanisms producing these impacts. This paper uses longitudinal data on cognitive and personality skills from an experimental evaluation of the influential Perry Preschool program to analyze the channels through which the program boosted both male and female participant outcomes. Experimentally induced changes in personality skills explain a sizable portion of adult treatment effects.
