While many Governments have turned to connected education and tech-driven programmes to support continued learning during school closures, there is little available evidence on the impact of distance learning on learning outcomes, especially for children affected by crisis and conflict and regarding holistic learning outcomes. Understanding the impact of the growing number of digital interventions on learning outcomes for these children (both in and outside of the classroom) is crucial to ensuring that no child is left behind in the wake of COVID-19 disruptions. In order to be able to understand how to better support children’s learning, we first need to be able to understand what children know and are able to do. Armed with this information, teachers and educational programmes can then provide more tailored support. The assessment of learning outcomes is therefore key. In response to a clear gap in this area, a new partnership, brokered by Porticus, brought together War Child Holland, NYU Global TIES for Children, and the HEA to interrogate the need for an effective tool to assess learning outcomes across digital learning interventions.
