What is the evidence of education in Jane Eyre?

Education is a theme throughout Jane Eyre.  When Jane was a girl, she was sent away to Lowood School.  It was a strict religious charity school for orphaned girls.  Jane received an education there under the rigid and cold instruction of the teachers and Mr. Brocklehurst, a minister in charge of the school.  Despite the challenges of Lowood School, Jane excelled and eventually became a teacher there.  She taught for two years.  Eager for a new experience, Jane took a position as a private governess to a young girl.  She left Lowood School to move to Thornfield.  Mrs. Fairfax, the housekeeper at Thornfield, described Jane as a "kind and careful teacher" to her young pupil.  

Later, Jane left Thornfield and found her cousins, St. John, Diana, and Mary. Diana and Mary soon had to leave to earn a living as governesses.  St. John asked Jane to take a position as a schoolmistress at the parish school for girls.  St. John thought that Jane would scoff at such a position, but she was eager to take it.  He told her that it was only a "'village school'" and that her pupils would "'be only poor girls... at the best, farmers’ daughters.'"  He worried that she would think such a position to be below her, because she would only be teaching "knitting, sewing, reading, writing, [and] ciphering."  Jane told him that she was not an ambitious person.

Education is important in Jane Eyre.  Much of Jane's childhood takes place at Lowood School.  Later, she becomes a teacher there, at Thornfield, and at the village school.  Her cousins, Mary and Diana, are also governesses.  Jane clearly loves teaching and learning.  She is a good and devoted teacher and she values education.
