In order to streamline the administration of its technical assistance programs, as well as to facilitate the application process, NADB merged the two programs—the Institutional Development Cooperation Program (IDP) and the Project Development Program (PDP)—into a single program called the Technical Assistance Program (TAP). The general objectives, criteria and operating procedures of the new program remain the unchanged. More detailed information on the merged program is available at: Technical Assistance Program.

NADB provides technical assistance to project sponsors for the purpose of strengthening their financial performance and ensuring the long-term sustainability of their infrastructure. Technical assistance may be used for studies related to the design and implementation of environmental infrastructure projects, as well as for capacity-building measures aimed at achieving effective and efficient operation of public services.
