Investigative Services Bureau
Polygraph Unit

For over 40 years, the New Hampshire State Police Polygraph Unit has offered forensic polygraph support to law enforcement. The Polygraph Unit is comprised of expertly trained and certified Forensic Polygraph Examiners. These examiners provide a valuable investigative tool to local, county, state, and federal law enforcement agencies, as well as to the Department of Corrections, Office of the Attorney General, and the various County Attorney Offices throughout the state.

Forensic polygraph examinations are used daily to affirm or dispel individuals suspected in criminal cases for law enforcement agencies.  Utilizing this tool assists in narrowing investigative issues and lowers investigative expenses.  The Polygraph Unit is also requested to administer examinations for the purposes of law enforcement employment.  Every Trooper candidate is required to submit and pass this examination prior to employment.

The Polygraph Unit continues to perform at the highest level of professionalism.  The commitment and dedication of the Polygraph Examiners remains the model for polygraph services throughout New Hampshire.
