NITRD Program Component Areas (PCAs)

As required by law, the annual NITRD Supplement to the President’s Budget is organized by Program Component Areas (PCAs), where the PCAs are major subject areas for Federal IT R&D. PCAs are intended to facilitate budgetary comparisons from year to year in each area. However, the PCA set does evolve over time, reflecting changes in IT R&D activities at federal agencies and IT R&D priorities of the Administration.

The annual PCA pages linked below present the PCA set for each annual NITRD Supplement, summarize the PCA changes from year to year, and indicate how NITRD coordination activities, which are conducted by NITRD Interagency Working Groups (IWGs), are reported under the PCAs.
