On arrival, candidates are allocated a number (used instead of one's name) and placed into teams known as groups. They remain in these groups for the duration of the board, making it common for strong friendships to develop during the process. As candidates are assessed against a standard and not against each other's performance (there are no set quotas for acceptance – if you meet the standard you pass), it is not uncommon that strong groups will see a large proportion of their members meet the standard.
