On the first part of the question, I am not in a position to tell you the success rate for candidates who receive training for the number of weeks allowed for attaining the level required. That is a question of individual performance.
On the question of meeting the two year limit, my colleague can give you figures regarding the exclusion orders granted. There is no follow-up where the person fails. But where the person succeeds, we don't know whether it took eight or 12 weeks, or 14 or 23 months; we don't have that information.
