Our Polygraph Services:


All examinations are audio and video recorded. Each examination is conducted on the latest computerized polygraph instrument using the most up to date sensing components and motion sensor equipment. If required, remote monitoring capabilities are available.

  • Criminal Examinations: Examinations are conducted for defense attorneys as well as prosecutors in an attempt to determine the truth. The polygraph is an effective tool in identifying the individual(s) involved in the criminal conduct under investigation; however. it is most effective in eliminating the individual who is unjustly accused of a criminal act they did not commit.

  • Pre-employment Examinations: We administer pre-employment/screening examinations for law enforcement agencies and armored car companies. We can assist agencies in the background investigative process by verifying the information submitted by an applicant and determining whether or not any of the provided information is false or misleading. We also can determine whether or not the applicant has failed to disclose any disqualifying information.

  • Domestic/Fidelity Issue Examinations: if you suspect that your significant other has betrayed your trust, or they have accused you of betraying their trust, a polygraph can be administered to verify the truth.

  • Probation and Parole compliance: We conduct examination of parolees and probationers to determine if an offender on supervision is abiding by the conditions of his/her parole or probation. The examinations can be administered to identify new criminal activity, drug, or alcohol use, weapon possession, or any other violation of the individual's conditions of parole/probation.

  • Employer requested: Employers who suffer an economic loss relating possibly to an employee theft, might ask an employee to take a polygraph to attempt to resolve the issue and solve the theft. This type of examination must meet the strict guidelines of the Employees Polygraph Protection Act (EPPA). The guidelines are very specific and the penalties are severe. Before an employee is asked to take a polygraph, the employer must research EPPA and fully comply with its rules and regulations. Information on EPPA can be found at www.polygraph.org/eppa.com. Contact us for additional information.

  • Immigration/Asylum Issues: Polygraph testing of individuals seeking asylum are used to determine the validity of the claims of the petitioner in federal courts in immigration cases. The statements of the petitioner requesting asylum can be verified by a polygraph examination. The results of the examination can assist the asylum officer and/or immigration judge in making an informed decision with regard to granting or withholding asylum.

  • Post Conviction Sex Offender Testing (PCSOT)

Incident Offence/Specific Issue: This examination is utilized to verify the facts surrounding the specific acts that lead to the criminal conviction of the offender. It is primarily used when the offender is in denial of the criminal misconduct. The specific Issue test is also used if there is a specific event in question, such as re-offending, or failure to follow one or more of the supervision guidelines.

Maintenance: This test is utilized to confirm the offender's progress and his/her compliance with his/her probation/parole conditions.

Monitoring: This test is administered to confirm the offender's progress and compliance to the guidelines of the treatment provider.


Sex History/Disclosure: This examination is sometimes referred to as the Psycho-Sexual Evaluation Statement verification. It is used to verify the accuracy of the offender's disclosure of his sexual history to the treatment provider. It is used to determine the extent of the offender's deviancy and to determine if there are additional victims and/or additional offenses committed by the offender.


  • Therapeutic testing: Like the PCSOT testing, this examination is completed to assist treatment providers in overcoming the client's denial and in determining treatment compliance issues.
