Several studies in developing countries have found that children who experience growth faltering in the first years of life show lower cognitive abilities than their peers. In this study, we use the Young Lives longitudinal dataset in Peru to analyse whether attending pre-school affects cognitive abilities at age 5 years, and if there is an interaction with HAZ at age 1 year. Using instrumental variables we found, for receptive vocabulary, a positive effect of attending Jardines (formal pre-schools); the effect of attending PRONOEI (community-based) pre-schools was not significant.
