This system-wide evaluation report assesses the effectiveness of the United Nations Development System’s (UNDS) Socio-Economic Response to COVID-19. As the first UNDS system-wide evaluation, this report provides stakeholders with an overarching perspective that allows a look at the UNDS as a whole and assesses the extent to which it has been able to collectively bring its strengths and capacities to bear for countries in their recovery towards the Sustainable Development Goals.
