We just finished our Spring PCSOT course. We have a few seats left in our next Basic Course which starts in June. Come to the school that pioneered the SIST, the only pre-employment and PCSOT screening technique with evidence based support.

Congratulations to these students who finished our basic examiner course. I want to thank the Pearland Police Department for hosting this course. This is a great bunch of people who will be an asset this to polygraph!

There are several incredibly important articles in the newly published American Polygraph Association magazine. I hope you read my article on the lack of research for multi issue screening tests and the need for successive hurdles testing. Please read Chip Morgans article on multi issue testing. I also ask that you read Ray Nelsons rebuttal. Please comment with your personal opinion on whether the meta analysis is not a policy document as Ray suggests. These 3 articles are important discussions on polygraph testing.
