Voluntary Organizations for Professional Evaluation (VOPEs): Learning from Africa, Americas, Asia, Australasia, Europe and Middle East
This book is focused on case studies highlighting the experiences of regional and national VOPEs. They share their experiences in strengthening the capacities of individual evaluators to produce credible and useful evaluations, the institutional capacities of the VOPEs themselves, promoting equity-focused and gender-responsive evaluations, and, especially, the roles VOPEs are playing to improve the enabling environment for evaluation in their countries.
