When are students allowed to leave the examination room?

Students who leave the examination room temporarily (for example due to ill health or in order to use the bathroom) must be accompanied by a member of staff. Candidates cannot leave the examination room completely until after the Key Time of the examination, unless the school keeps them under Full Centre Supervision until the Key Time. Candidates also cannot leave the examination room completely until instructed to do so by the examinations officer/invigilator.
