The UNFPA programmes of Bosnia and Herzegovina, North Macedonia, Serbia and Kosovo have a harmonized programme cycle ending in 2020, and therefore the Cluster Programme Evaluation of all four programmes is part of the UNFPA quadrennial evaluation plan (DP/FPA/2018/1) approved by the Executive Board. The combination of the four UNFPA programmes that form one administrative cluster permits the identification of common higher-level findings that can inform future UNFPA activities. The overall purpose of the Cluster Programme Evaluation is to: a) demonstrate accountability to stakeholders on performance in achieving development results and on invested resources, b) support evidence-based decision-making, and c) contribute important lessons learned to the existing knowledge base on how to accelerate the implementation of the International Conference on Population and Development (ICPD) Programme of Action.
