612.1 PURPOSE AND SCOPE
The purpose of this policy is to provide guidelines for the use of the computer voice stress analysis
(CVSA) examinations as investigative tools.
612.2 OPERATOR QUALIFICATIONS
Operators of the CVSA must have successfully completed a certified examiners course either
offered or sponsored by the National Institute for Truth Verification (NITV). Further, each certified
examiner must recertify by successfully completing an advanced or recertification course every
three years, commencing with the original certification. Recertification courses must be offered
or sponsored by the NITV.
612.3 PROCEDURES FOR THE USE OF THE CVSA
612.3.1 CRIMINAL INVESTIGATION
Requests are made to the CVSA examiner verbally or in writing. Requests must be accompanied
by sufficient data for evaluation of the subject. The decision to do an examination is based on the
nature of the investigation, data available, and the characteristics of the person to be examined.
Formal CVSA examinations may not be required or requested of any victim in a sex offense
involving the use of force, violence, duress, menace, or threat of great bodily harm.
612.3.2 PRE-EMPLOYMENT EXAMINATION
As part of the hiring process all applicants for employment with the Garden Grove Police
Department are subject to a pre-employment CVSA examination. The possibility of having to
undergo a CVSA examination shall be clearly stated in the appropriate job/recruitment flyer. The
use of results of the CVSA for the detection of deception shall not be the single determinant of
employment status.
612.3.3 INTERNAL INVESTIGATIONS
CVSA examinations may be used in Internal Affairs investigations on a limited basis. The
examination may be offered or administered to parties registering a complaint about the
department or officer and the complaint witnesses.
In keeping with the California Peace Officers' Bill of Rights, CVSA examinations will not be offered
to sworn members of the department. If they are considered, requests must be made in writing to
the Chief of Police and must contain reasons for the request. The CVSA is considered only when
the truth cannot be established by standard investigation.
612.4 DENIAL OR DELAY BY THE EXAMINER
If the CVSA examiner has reason to believe that an examination may not be advisable for a
criminal investigation, pre-employment or Internal Affairs investigation, the examiner may delay

by connection with investigations in this order.
