These Guidelines have been prepared by the UNEG Peer Review Working Group and are intended to facilitate the preparation, conduct and use of future UNEG Peer Reviews and other modalities for the assessment of UN evaluation functions. The Guidelines, originally developed in 2014 and considered an ongoing draft, build on the UNEG Framework for Professional Peer Reviews of the Evaluation Function of the UN Organizations (2011) and incorporate a normative assessment framework based on the revised UNEG Norms and Standards (2016).
