Unlike the CIA and NSA polygraphs, DIA polygraphs are only of Counterintelligence Scope (CI), rather than Full Scope (FS) (also known as Expanded Scope Screening or ESS), which is ostensibly more intrusive as far as one's personal life is concerned. DIA administered only a handful of FS polygraphs and only for those personnel who were to be detailed to the CIA. Additionally, DIA conducted a handful of FS polygraphs on its personnel remaining overseas in excess of 6.5 years, although this practice appeared to be outside the scope of DIA's authorization at the time.
