The Apprentice Rank is earned after a Junior ranked Scarf Hero has earned enough Wiki edits. The perk to this rank is having a "tag" enabled next to your username. This means that the username in forums or comments will be able to have a small title in parenthesis beside it.
To become promoted to this rank, users must have around 250-600 edits. Being ranked up also depend on trust and dedication to the Wiki and it's members.
