The Global Evaluation Reports Oversight System (GEROS) is a UNICEF-wide system managed by the Evaluation Office. It is used to assess the quality of final evaluation reports. The main objectives of GEROS are: to provide senior managers with an independent assessment of the quality of their evaluation reports; to strengthen the internal evaluation capacity to improve the quality of the evaluations; to contribute to corporate knowledge management and organizational learning; and to report to Senior Management on the quality of evaluation reports – generating key performance indicators that point to the improvements, strengths, and weaknesses of overall final evaluation reports. To meet these objectives, all final evaluation reports are assessed and rated externally by an independent firm according to the UNEG Evaluation Report Standards for UNICEF, and a final analysis is done using all of the reviewed evaluation reports’ ratings to study their overall trends, strengths and weaknesses.
