Events and experiences in the early years of life have long run consequences; deficits accumulated during this period are very difficult and expensive to reverse in later life. The challenge faced by governments and policy makers is to identify interventions that are effective at improving child development, yet at a reasonable cost and that are sustainable in the longer run. In this research, we implemented an early childhood intervention that could be scaled up at reasonable cost, given the policy context and the resources (financial and human) available in Colombia, and have evaluated its impact. The evaluation, based on a randomised controlled trial, looks at the immediate effects on children’s development.
