NDI, along with the International Republican Institute (IRI) and with funding from the United States Agency for International Development, helps to support the House Democracy Partnership (HDP). HDP is a bipartisan commission of the U.S. House of Representatives that facilitates exchange programs and aims to strengthen democratic legislatures in new or restored democracies. HDP creates opportunities for international peer-to-peer learning between members of parliament and parliamentary staff, and provides technical expertise to enhance accountability, transparency, legislative independence, and government oversight to address the challenges commonly faced by partner legislatures. Current HDP partners include the parliaments of Afghanistan, Colombia, Georgia, Haiti, Indonesia, Iraq, Kenya, Kosovo, Kyrgyzstan, Liberia, Macedonia, Mongolia, Pakistan, Peru, Sri Lanka, Timor-Leste, Tunisia, and Ukraine. Burma/Myanmar and Nepal currently participate as observers.
To support HDP, NDI has organized exchanges that have engaged over 1,300 members of parliament and parliamentary staff. Exchanges provide delegates with the opportunity to observe the U.S. legislative system, to access technical expertise on legislative operations, and to share and exchange legislative good practices with colleagues from participating countries. HDP participants often build relationships with one another, which can facilitate continued knowledge sharing beyond the exchange programs, encourage follow-up on ideas raised during the exchange, and help to build multi-partisan political will for democratic parliamentary reform.
