This guide is aimed to propose a holistic, systemic, and easy-to-use methodology that is multiscalar, multisectoral, and multidimensional for the M&E of public EAS systems to help identify gaps and pathways to strengthen and reform the public EAS system. It starts with analyses of the common objectives, subject, challenges, lessons learned, and prospects of the existing M&E systems and expounds on the logical framework, rationale and objectives of the proposed M&E methodology from a multistakeholder perspective. Then it proposes M&E frameworks at the national and grassroots levels following such order as the introduction, key M&E elements, indicator framework, and operational framework. Next, it looks at the issues of data sources, data collection, and capacity building, focusing on the institutionalization of the M&E system in the public EAS. Finally, it introduces the commonly used tools and methods of data analysis, focusing on the weighting of indicators, scoring methods, and integrated analytical frameworks.
