How does Jane Eyre journey from childhood towards maturity?

Jane Eyre journeys from childhood to maturity through attending Lowood school. She is sent to the charity boarding school after she responds with an outburst of violence to the repeated bullying assaults of her cousin.
Lowood school at first seems a terrible place and in many ways it is. It is run harshly in order to teach the girls their lowly "place" in society. The girls are forced to have rough, short haircuts and wear plain clothes. They are often cold and don't get enough to eat. Some, like Helen Burns, even die of diseases presumably brought on by the harsh conditions.
Nevertheless, the school transforms Jane. For the first time in her life, she is an equal among the other students. When an early attempt to humiliate her by labeling her a liar fails, Jane learns she can be appreciated on her own merits. She develops friendships for the first time, most notably with Helen Burns and Miss Temple. For the first time, she feels loved. Both Helen and Miss Temple help teach her to control her anger.
Jane develops a deep hatred of injustice from being abused in her aunt's household. She forms a strong moral center at Lowood School as she bonds with others there. By the time she emerges from the school, she is a mature young woman with a strong character. She is strong enough both to attract Mr. Rochester and resist him.
