The COVID-19 pandemic has compelled an immediate response by the development evaluation community. Evaluation is an important instrument for effective development policy. Building on informal consultations in a series of knowledge-sharing exchanges, consultations and webinars convened by OECD/DAC Network on Development Evaluation (EvalNet) and the Independent Evaluation Office of UNDP we have jointly prepared this guidance note capturing good practices for evaluation units during COVID-19. The note suggests a framework of operational and methodological options and action areas. It also includes a set of reference material drawn from a wider professional evaluation community. Although the guidance does not aim to represent a consensus or a prescriptive framework for COVID-19 related action, we hope you find the guidance and references useful.
