A polygraph examination consists of three distinct phases
- The Pre-Exam Interview;
- The Polygraph Exam;
- The Post-Exam Interview.
During this first phase, the examiner will:
- inform the examinee of the specific purpose of the examination;
- advise the examinee of his or her constitutional rights, of their right to retain legal counsel and of their voluntariness with regards to the examination;
- will determine if the examinee is suitable to take a polygraph examination;
- provide the examinee with a detailed explanation of the polygraph exam procedure, of the instrumentation and its components;
- obtain the examinee's version of the facts regarding the specific issue;
- formulate and review with the examinee all the questions that will be asked during the polygraph examination.
Polygraph Exam Phase
During this second phase, the examiner will:
- place the components on the examinee's body, thereby connecting him or her to the polygraph instrument;
- conduct a calibration test to ensure that the polygraph is in good working order at the time of the examination;
- proceed with the actual polygraph examination. The examiner will ask the set of questions that were formulated and reviewed during the pre-exam interview. That set of question will be asked a minimum of three times with a pause in between series.
During this last phase, the examiner will:
- analyze the examinee's physiological data collected during the examination phase;
- inform and discuss the results with the examinee, which will be one of the following :
|No Deception Indicated (NDI)
||The Examinee is telling the truth
|Deception Indicated (DI)
||The Examinee is not telling the truth
||No Opinion can be rendered
||Insufficient Data collected
All examinations will be administered by a professionally trained and certified polygraph examiner (polygraphist) using a state-of-the-art system of computerized polygraph technology.
The examiner will adhere to the highest standards of excellence and ethics as required by the Code of Ethics of the Canadian Association of Police Polygraphists.
Careful attention must and will be given to every person being examined. Every examinee will be treated with respect, dignity and impartiality.
