National Intelligence Estimate - General Overview

General Overview

NIEs are considered to be "estimative" products, in that they present what intelligence analysts estimate may be the course of future events. Coordination of NIEs involves not only trying to resolve any inter-agency 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 comprises the DNI and other senior leaders within the Intelligence Community.

National Intelligence Estimates were first produced in 1950 by the Office of National Estimates. This office was superseded in 1973 by National Intelligence Officers. This group of experts became the National Intelligence Council in 1979. In the early years, the National Intelligence Council reported to the Director of Central Intelligence in his role as the head of the Intelligence Community; however, in 2005, the Director of National Intelligence became the head of the Intelligence Community.

The Intelligence Community’s faulty assessments on Iraqi WMD in 2002 highlights the role Congress plays in promoting the analytic rigor and utility of strategic intelligence assessments, such as National Intelligence Estimates.
