There are 3 security levels:

  • Counter Terrorist Check (CTC): is carried out if an individual is working in proximity to public figures, or requires unescorted access to certain military, civil, industrial or commercial establishments assessed to be at particular risk from terrorist attack
  • Security Check (SC): determines that a person’s character and personal circumstances are such that they can be trusted to work in a position that involves long-term, frequent and uncontrolled access to SECRET assets
  • Developed Vetting: (DV) in addition to SC, this detailed check is appropriate when an individual has long term, frequent and uncontrolled access to ‘Top Secret’ information. There is also Enhanced DV.
