Prepared for the World Bank Institute, this report examines five parliamentary assessment frameworks developed by different organizations in order to understand how and to what degree they differ. These frameworks are the National Democratic Institute Standards (NDI Standards), the Commonwealth Parliamentary Association/World Bank Institute/United Nations Development Programme Benchmarks (CPA/WBI/UNDP Benchmarks), the Inter- Parliamentary Union Self-Assessment Toolkit for Parliamentarians (IPU Toolkit), the Parliamentary Centre - Budget Process (PC-Budget) framework, and the Parliamentary Centre - Parliamentary Audit (PC-Audit) framework. Our report compares frameworks in terms of their composition, their performance on good question design, and the differential scores they generate when applied to sample countries. We then propose a holistic framework based on areas of agreement between frameworks, which may assist these different organizations in harmonizing their frameworks in the future.
