The purpose of this document is to provide guidance and supplemental information to assist with country assessments of debt management performance, using the Debt Management Performance Assessment (DeMPA) tool. The DeMPA is a methodology used for assessing public debt management performance through a comprehensive set of 15 performance indicators spanning the full range of government debt management (DeM) functions. It is based on the principles set out in the IMF and World Bank Guidelines for Public Debt Management (Guidelines), initially published in 2001 and updated in 2003.1 It is modeled after the Public Expenditure and Financial Accountability (PEFA) framework for performance measurement of public financial management.
