My wife is a high school art teacher in a public school.
She went to 4 years of undergrad college and passed her teaching certification. She also had teaching experience while growing up.
She has now completed her Master's in Art Education, which also cost a goodly amount of money and with the public system the way it is, barely got reimbursed for tuition (thankfully it is all tax-deductible). She makes a fairly nice salary and has a great benefits package, but the way the county treats it's 9-month employees, she only pulls a paycheck while school is in session. Other counties offer the option to defer, thereby allowing you to get paid for 12 months, albeit at a lower lump sum (due to there being more pay periods), but ours does not.
