Quality, timely, purpose-driven education in emergencies (EiE) data can enable more effective response to education needs in crisis settings and strengthen system resilience. However, a growing body of evidence points to a number of problems related to the production, sharing, and use of EiE data within education information management systems (EMIS). This Guidance Note aims to support efforts towards a deliberate, shared, and committed course of action that eventually becomes part of routine planning and management of the education system, drawing on good practices and consolidating existing resources in a range of institutional, organizational, and individual elements to be considered when working to embed and improve production and use of EiE data for system resilience. This Guidance Note aims to support the work of ministry of education (MoE) and humanitarian and development actors at national and sub-national levels to institutionalize EiE data within education systems as part of broader system strengthening and resilience. This Guidance Note provides concrete guidance for data managers, decision-makers, and partners seeking to institutionalize EiE data production and use for crisis-sensitive educational planning and management. It is organized in two parts: the first sets out a framing model of institutionalized EiE data, while the second drills down into different components of the model, providing a series of reflections and resources for strengthening institutional awareness, capacity, and commitment to production and use of quality and timely EiE data.
