Incident Specific Polygraph Tests
This type of examination is administered when there is a clearly defined incident that is being investigated. The test seeks to establish whether the examinee should be considered as a possible suspect in the ongoing investigation of the matter. This type of test is usually used to investigate theft, fraud, armed robbery, murder etc. This type of examination can be used to further an investigation where a suspect has already been identified or to isolate a suspect in a group when no suspect has yet been identified.
Pre Employment Polygraph Tests
This type of examination is administered to prospective employees. The test questions are structured to ask about a number of issues such as previous involvement in theft from employers, undisclosed drug use, commission of serious crimes and falsification of employment application information. This testing helps the employer identify those candidates that are concealing adverse information regarding their background.
Ongoing Screening Polygraph Tests
This type of test is administered to existing employees who work in high risk environments within the business where they have access to high value goods, for example. This type of test can focus on a single issue such as involvement in theft from the business or it can be expanded to include drug use and commission of other crimes. Regular periodic testing of employees helps to maintain a high level of integrity amongst staff.
