[Star Wars] What do you actually have to do to achieve the Rank of Jedi Master? Why can you be on the council but not a Master?

Anakin was a special case, normally people are not allowed on the council without being masters. 

Because Anakin was so integral to their plan to investigate Palpatine, he was given permission to serve on the council - likely as an advisory position but without actual power to command the Jedi Order (most likely because he was too young an inexperienced, and not emotionally stable enough to trust with that much authority).
