Gradjet was created by the Committee for Development Policy (CDP) Secretariat with the help and input of various international agencies and entities including the Commonwealth Secretariat; UN Conference on Trade and Development; UN Office of the High Representative for Least Developed Countries, Landlocked Developing Countries and Small Island Developing States; and the World Trade Organisation.

The CDP is a subsidiary body of the United Nations Economic and Social Council. CDP provides inputs and independent advice to the Council on emerging cross-sectoral development issues and on international cooperation for development, focusing on medium- and long-term aspects. The Committee is also responsible for reviewing the status of least developed countries (LDCs) and for monitoring their progress after graduation from the category. The 24 members of the Committee are nominated by the United Nations Secretary-General in their personal capacity, and are appointed by the Council for a period of three years. Membership is geared to reflect a wide range of sustainable development experience as well as geographical and gender balance.

The Secretariat of the CDP forms part of the Development Policy Analysis Division of the UN Department of Economic and Social Affairs (UNDESA) and provides substantive and administrative assistance to the Committee. While servicing meetings of the CDP, the Secretariat formulates and implements its own substantive work programme, including quantitative and qualitative analyses, particularly relating to the 2030 Development Agenda and the LDCs.

The Secretariat prepares reports to intergovernmental bodies such as Economic and Social Council, the General Assembly and other policy-making organs, as appropriate, including on the identification and graduation of LDCs; unilateral coercive measures; and third States affected by UN sanctions.

The Secretariat also formulates and implements capacity development and policy-advisory activities on various development issues. Activities focus on training and advising stakeholders in developing countries, particularly LDCs, to enhance their capacities in achieving sustainable growth. Among its recent outputs are the design and implementation of of analytical and operational tools, for instance the LDC support measures portal, cost-benefit analysis, and ePing trade notifications system.
