We study the socio-economic gradient of child development on a representative sample of low- and middle-income children aged 6-42 months in Bogota, using the Bayley Scales of Infant Development, a high quality test based on direct observation of the child's abilities. We find a statistically...

Medir el desarrollo infantil temprano (DIT) mediante pruebas estándar de diagnóstico en estudios a gran escala resulta difícil y costoso. Por esto, con frecuencia se utilizan pruebas de tamizaje multidimensionales y pruebas que miden un solo dominio del desarrollo como alternativas (nos...

In low- and middle-income countries (LIMCs) measuring early childhood development (ECD) with standard tests in large scale surveys (i.e. evaluations of interventions) is difficult and expensive. Multi-dimensional screeners and single-domain tests ('short tests') are frequently used as...

As home visiting programs continue to expand, it is crucial to develop cost-effective methods to monitor their quality that are feasible at-scale. This paper compares two instruments widely used among home visiting services in the US to a simpler checklist in the context of Peru's Cuna Mas...

This document compares three versions of the same home visiting model, the well-known Jamaica model, which was gradually scaled-up from an efficacy trial (proof of concept) in Jamaica, to a pilot in Colombia, to an at-scale program in Peru. It first describes the design, implementation and...
