Developed Vetting (DV)
Developed Vetting allows routine and unrestricted access to material marked 'top secret' and below.
DV clearance will normally consist of:
* a check against the National Collection of Criminal Records and relevant departmental and police records
* in accordance with the Security Service Act 1989, where it is necessary to protect national security or to safeguard the economic well-being of the United Kingdom from threats posed by persons outside the British Islands, a check against Security Service records
* credit references checks and a review of personal finances
* an interview with the person being vetted
* references from people who are familiar with the person's character in both the home and work environment. These may be followed by interviews. Enquiries will not necessarily be confined to past and present employers and nominated character referees.
* clearance is re-examined following any stressful encounter, this includes a psychological re-evaluation.
DV clearance is subject to review over a period not exceeding eighteen months.
