A National Intelligence Estimate (NIEs) expresses the coordinated judgments of the Intelligence Community, and thus represents the most authoritative assessment by the Director of National Intelligence with respect to a particular national security issue. It is considered to be an “estimative” intelligence product, in that it addresses what intelligence analysts believe may be the course of future events.
Coordination of NIEs involves not only trying to resolve any interagency differences, but also assigning confidence levels to the key judgments and rigorously evaluating the sourcing for them. Each NIE is reviewed and approved for dissemination by the National Intelligence Board (NIB), which is comprised of the DNI and other senior Intelligence Community leaders within the Intelligence Community.
