"The purpose of this guidance is to clarify the concept of quality in developmental evaluations managed by UNFPA. It is intended to increase the understanding of UNFPA evaluation staff, external evaluation consultants, and those contracted to carry out quality assessment of UNFPA developmental evaluations, of how the principles of developmental evaluation and the UNEG evaluation standards translate into UNFPA evaluation quality assurance and assessment work. This in turn will improve the overall quality of developmental evaluations and support the effective use of evaluative evidence for programming and policy decisions." (Introduction)
