Know The Truth Before You Employ
A truth verification pre-employment screening test is a valuable component of a comprehensive hiring process. It enables organizations to identify potentially undisclosed or undetected behaviors that may be relevant to a candidate’s suitability for a role, helping to support informed and responsible hiring decisions.

We also screen existing employees every 6 months to ensure that they have not become involved in undesired activities since they have been hired.
