CVSA Recertification

CVSA Certified Examiners Course

Our Expert Instructors conduct the widely acclaimed and intensive five-day CVSA® certification course, which is hosted by select law enforcement agencies across the USA. With small class sizes, there is ample hands-on instruction in the use of the CVSA.

Additionally, the specialized Defense Barrier Removal (DBR®) interviewing and interrogation technique developed by our founder is also taught. This technique, when utilized in conjunction with the CVSA®, has proven invaluable in obtaining admissions and confessions, as well as clearing suspects.

CVSA Recertification

NITV Federal Services conducts re-certification courses in conjunction with the National Association of Computer Voice Stress Analysts (NACVSA) at select locations across the USA, which are usually hosted by law enforcement agencies. We encourage you to join the NACVSA as it is the only professional association in the world 100% devoted to supporting the interests of CVSA Examiners. Our dedicated re-certification courses are specifically designed for seasoned examiners and are three-days in length.

The annual Advanced Continuing Education Conference, held in Florida, is a five-day advanced training event featuring nationally and internationally recognized experts in subjects directly related to the CVSA, including current CVSA scientific and technical advances, interviewing and interrogation, pre-employment and background investigations, specialized investigations, and much more.

The NITV Federal Services will only recertify examiners who have completed a course taught by our approved Instructor, regardless of the organization sponsoring the training. 

To ensure our examiners are at their best, all examiners must recertify every two calendar years.
