We evaluate whether the Juntos conditional cash transfer program in Peru has a larger effect on children who benefited initially from the program during the first 4 years of life compared with those children who benefited initially between ages 5 and 8. The former group was exposed during early-life sensitive periods, received the program for a longer period, and received more growth monitoring sessions and vaccinations. We find that exposure to Juntos led to an improvement in nutritional status and in cognitive achievement, both of which were greater, but only the latter was significant for those initially exposed during the first 4 years of life.
