    General Information

    Vetting process

    Every interpreter on the WITS register has to be vetted either to an Enhanced DBS or an NPPV Level 3 standard (National Police Personnel Vetting Level 3). The Enhanced DBS level of clearance permits our interpreters to be appointed to Health Board and Local Authority work. The NPPV Level 3 clearance is vetted at a higher level which permits interpreters to be appointed criminal justice sector work. We will carry out the necessary vetting on acceptance of your application. We will send you more information about this once your application has been accepted.
