The website of the Department of Defense Polygraph Institute, which has responsibility for the training of all federal polygraph examiners, features a calendar that includes the training schedule for the polygraph examiner basic course.

Interestingly, training on polygraph countermeasures is reserved for the very last day of classes, and consists of only four hours of classroom instruction followed by three hours of practical exercises.

Perhaps this block of instruction is so short (and included almost as an afterthought) because DoDPI has no reliable methodology for the detection of countermeasures. ;)
