Invigilators must be satisfied about the identity of every candidate attending each examination.  The Head of Centre must ensure that arrangements are in place to enable invigilators to carry out thorough identity checks. Private candidates who are not known to Alpha Tutorials staff must present documentary evidence of their identity (e.g., an ID photo-card or a passport) before entering the examination room, and this should be checked each time the candidate attends an examination to ensure that they are the same person who was entered for the examination.
