Congressional Budget Justifications

NIDDK submits a Congressional Budget Justification annually in support of the President's Budget Request. This document details NIDDK's mission, research priorities, and budget-related activities for the upcoming federal fiscal year (FY). The FY runs from October 1 until the following September 30. More than 80 percent of the NIDDK’s funding is awarded through competitive grants NIH external link to researchers and students at universities, medical schools, small businesses, and other research institutions across the Nation. About 10 percent of NIDDK’s budget funds additional research at NIDDK’s own laboratories on NIH’s Bethesda, Maryland, campus, and in Phoenix, Arizona.
