Measuring and forecasting progress in education: what about early childhood?

A recent Nature article modelled within-country inequalities in primary, secondary, and tertiary education and forecast progress towards Sustainable Development Goal (SDG) targets related to education (SDG 4). However, their paper entirely overlooks inequalities in achieving Target 4.2, which aims to achieve universal access to quality early childhood development, care and preschool education by 2030. This is an important omission because of the substantial brain, cognitive and socioemotional developments that occur in early life and because of increasing evidence of early-life learning's large impacts on subsequent education and lifetime wellbeing. We provide an overview of this evidence and use new analyses to illustrate medium- and long-term implications of early learning, first by presenting associations between pre-primary programme participation and adolescent mathematics and science test scores in 73 countries and secondly, by estimating the costs of inaction (not making pre-primary programmes universal) in terms of forgone lifetime earnings in 134 countries. We find considerable losses, comparable to or greater than current governmental expenditures on all education (as percentages of GDP), particularly in low- and lower-middle-income countries. In addition to improving primary, secondary and tertiary schooling, we conclude that to attain SDG 4 and reduce inequalities in a post-COVID era, it is essential to prioritize quality early childhood care and education, including adopting policies that support families to promote early learning and their children's education.

Analysis of socioeconomic gradients in the development of children aged 0-3 years in Fortaleza, Northeastern Brazil.

OBJECTIVE: To identify the socioeconomic gradients in the measures of development and well-being of children under three years of age in Fortaleza, Northeastern Brazil. METHODS: We compiled information using a socioeconomic survey instrument, collecting anthropometric measurements, observing the home environment, and applying the Denver Test II to 2,755 children aged between zero and 28 months who are potential beneficiaries of the Cresça com Seu Filho program in Fortaleza. These children were randomly selected from a universe identified from the administrative record of the Cadastro Único of the Ministry of Social Development of Brazil. For the analysis, we reported descriptive statistics, Pearson correlations, and mean differences. RESULTS: Rates of chronic malnutrition and overweight were 7.0%. The results of the Denver II test indicated that personal social (23%) and language (20%) are the domains in which children have the highest developmental delay, when compared with the international reference sample. Parental practices measured by two sub-scales of the Home Observation of the Environment Inventory were poor, with only 14.0% of families having two or more books in the home and 35.0% of the households reporting having spanked their child in the past three days. CONCLUSIONS: We identified clear socioeconomic gradients in the anthropometric indicators, parenting practices, and the Denver Test II (especially in the language domain). Children from poorer households, as well as children of mothers with lower education levels, perform poorly on most measures.

RESUMEN OBJETIVO Identificar los gradientes socioeconómicos en medidas del desarrollo y bienestar en menores de tres años en Fortaleza, Nordeste de Brasil. MÉTODOS Se recolectó información a través de una encuesta socioeconómica, toma de medidas antropométricas, observación del ambiente en el hogar y aplicación del Test de Denver II de 2.755 niños de cero a 28 meses potenciales beneficiarios del programa Cresça com Seu Filho en Fortaleza. Estos niños fueron seleccionados aleatoriamente de un universo identificado a partir del registro administrativo del Catastro Único del Ministerio de Desarrollo Social de Brasil. Para el análisis se reportan estadísticas descriptivas, correlaciones de Pearson y diferencias de medias. RESULTADOS Las tasas de desnutrición crónica y el sobrepeso fueron iguales a 7,0%. Los resultados del Test de Denver II indicaron que las áreas en las que los niños presentan un mayor rezago en su desarrollo, cuando se compararon con la muestra de referencia internacional fueron personal-social (23,0%) y lenguaje (20,0%). Las prácticas parentales medidas por dos sub-escalas del Hom e Observation of the Enviroment fueron pobres, solo el 14,0% de las familias reportaron tener dos o más libros en el hogar y 35,0% de los hogares reportaron haberle pegado a su hijo en los últimos tres días. CONCLUSIONES Se identifican gradientes socioeconómicos claros en los indicadores antropométricos, las pautas de crianza y en la prueba Denver II (especialmente en el dominio de lenguaje). Los niños pertenecientes a los hogares más pobres, así como hijos de madres con menor nivel educativo, presentan un desempeño bajo en la mayoría de las medidas.

Investing in the foundation of sustainable development: pathways to scale up for early childhood development.

Building on long-term benefits of early intervention (Paper 2 of this Series) and increasing commitment to early childhood development (Paper 1 of this Series), scaled up support for the youngest children is essential to improving health, human capital, and wellbeing across the life course. In this third paper, new analyses show that the burden of poor development is higher than estimated, taking into account additional risk factors. National programmes are needed. Greater political prioritisation is core to scale-up, as are policies that afford families time and financial resources to provide nurturing care for young children. Effective and feasible programmes to support early child development are now available. All sectors, particularly education, and social and child protection, must play a role to meet the holistic needs of young children. However, health provides a critical starting point for scaling up, given its reach to pregnant women, families, and young children. Starting at conception, interventions to promote nurturing care can feasibly build on existing health and nutrition services at limited additional cost. Failure to scale up has severe personal and social consequences. Children at elevated risk for compromised development due to stunting and poverty are likely to forgo about a quarter of average adult income per year, and the cost of inaction to gross domestic product can be double what some countries currently spend on health. Services and interventions to support early childhood development are essential to realising the vision of the Sustainable Development Goals.

Cost-benefit analysis of a micronutrient supplementation and early childhood stimulation program in Nicaragua.

This paper estimates the cost-benefit ratio for an integrated early childhood development program in Nicaragua (PAININ). Using longitudinal data, we estimate the average treatment effects of PAININ including micronutrient sprinkles on the prevalence of anemia and hemoglobin levels among disadvantaged children aged 6-36 months. We also estimate the effects of PAININ excluding sprinkles on cognitive outcomes among children aged 2.5-5 years. In the younger age group the program reduced anemia by 4 percentage points after 8 months and nearly 6 percentage points after 1 year; the latter is a 26% decrease in anemia. In the older age group, the program improved verbal and numeric memory after a year and a half, but the effects were modest (0.13 SD). When analyzing its potential impact on earnings, we conclude that the discounted annual costs of the program per child are less than the discounted annual increase in beneficiary earnings. Specifically, we estimate a cost-benefit ratio of 1.50 from the PAININ plus sprinkles package. Our sensitivity analysis suggests a range for this ratio between 1.30 and 2.30.
