When appointing senior executives, there may be a requirement for a more in-depth screening, particularly in circumstances where these individuals are likely to come into contact with valuable and highly sensitive business-critical information. Positive or cleared screening is very detailed and not only requires information about the candidate but also close family members and friends. It is normal practice that when all the information required has been obtained, the candidate is then interviewed about the information received, this procedure can also act as a type of integrity check, and is used extensively within the Police, Political and Armed Forces.
