This study is a causal impact evaluation of Watch, Play, Learn (WPL), a program by Sesame Workshop that consists of videos that aim to bring playful early learning opportunities to children, especially those affected by conflict and crisis, via mobile phones. This study focused on the effects of WPL math and social-emotional skills content delivered to Venezuelan migrants and Colombian children living in communities in Colombia where families and children face challenges in accessing essential services, including early education. Implementation was led by the Colombia office of Innovations for Poverty Action.
