pailryder:  not sure I agree with everything in your post;  No Opinion, at least within the DOD polygraph community, applies to results where sufficient charts have been collected, and numerically scored as N.O.;  N.O. also applies to exams where the exam was started but insufficient charts were collected to render any kind of opinion.  If exam is terminated after the collection of an ACQT but before completion of any relevant testing to render an opinion, it is also called N.O.

What makes you say that the feds control the APA?  APA is a private organization with no official connection/affiliation with the federal government;  it is not subject to federal polygraph oversight or policy.
