These data were collected as part of an ongoing practice, policy, and research partnership, Ahlan Simsim. Ahlan Simsim, which means “Welcome Sesame” in Arabic, is the groundbreaking program from Sesame Workshop and the International Rescue Committee (IRC) that delivers early learning and nurturing care to children and caregivers affected by conflict and displacement across the Middle East. Through a brand-new, localized version of Sesame Street and in-person direct services across Iraq, Jordan, Lebanon, and Syria, Ahlan Simsim reaches families wherever they are—from classrooms and health clinics to TV and mobile devices—with the vital educational resources that they need to thrive. This program, generously funded by the John D. and Catherine T. MacArthur Foundation and the LEGO Foundation, not only addresses immediate needs and builds a strong foundation for future wellbeing, but also has the potential to transform how the humanitarian system responds to crises around the world.
