Mentor

Mentors are warriors of a Clan who teach apprentices to be warriors.

Process
When a kit reaches six moons, he or she is given a mentor. The mentor teaches them how to fight, hunt, patrol, and prepares them for life as a warrior. When a leader assigns a new apprentice a mentor, they choose pairings based on seniority and whether or not the pair will be able to work together. Apprentices are rarely mentored by their own parents - they would be too lenient with their kits.

Warriors are able to request a kit they would like to mentor although this does not necessarily guarantee they will be chosen as a mentor to said kit once they reach six moons. Often a warrior will watch a kit they hope to mentor during kithood so as to become familiar with them before they are apprenticed.

Mentors can have more than one apprentice, but this is not frequent. Warriors require certain qualities to be mentors - for instance, Bluestar refrained from giving the ThunderClan warrior Runningwind an apprentice even though he was a senior warrior because she thought he wouldn't have enough patience to train an apprentice. However, it does not matter how experienced a warrior is: when a cat is made a warrior, they can then be a mentor at any time.

Leaders usually only train the deputy's kits and other kits of important heritage.

Special Cases
There are some things that can stop a kit or apprentice from becoming an apprentice or delay the apprenticeship. Known examples include:
 * Crookedpaw breaking his jaw and being sickly (Bluestar's Prophecy)
 * Cinderpaw breaking her leg (Fire and Ice)
 * Cinderpaw breaking her leg (Dark River)
 * Jaypaw being blind (The Sight)

However in many of these cases the apprentice or kit will either recover or train as a medicine cat apprentice. Both Cinderpelt and Jayfeather worked in the medicine den due to their ailments and were told they could not be warriors. Medicine cat apprentices are chosen by medicine cats, and unlike warrior apprentices, they remain apprentices even after receiving their full name, and continue to be until their mentor dies or retires.
