The PBO training program aims to strengthen the Cambodian Parliament’s capacity to perform its constitutional role of state budget oversight. The training program seeks to strengthen the capacity to perform some of the research tasks typically found in Parliamentary Budgetary Offices (PBOs). The capacity building will partly be done by producing the type of research that a PBO would do (through a learning-by-doing approach), thus serving Parliament with knowledge and perhaps also creating a demand and political will for eventually establishing a PBO.
