If she wants to teach, she needs to think seriously about where she wants to wind up. Different states have different testing and licensing requirements and there may not always be reciprocity. Look for NCATE accreditation as it may be easier to gain reciprocity. Check the requirements for each state for initial certification, licensing and retention of credentials.
My D attended a 5 year program at a SUNY school. It was a direct admit after the first semester, so she didn’t have to deal with applying to grad school and she was able to take her first semester (of 3) of grad classes at undergraduate tuition.
Another thing to think about is job security and tenure. In NYC and most of NYS that I am familiar with, once a teacher gets tenure, they pretty much have to kill the principal or sleep with students to lose their jobs. In other areas, teachers get a contract every year or so and aren’t guaranteed to be rehired. One of my friends, in California, found herself looking for new jobs every other year, often due to budget issues, sometimes because she is a strong woman who doesn’t handle incompetent admins well.
Also, in many places, teachers don’t get paid excessively well, so you might not want a lot of student debt. There may be some programs that forgive debt if you teach in certain areas or subjects but I last explored these almost 10 years ago. Once D decided on a SUNY, she didn’t have to rely on loans. I would venture a guess that some of these programs may face cuts or elimination in the new tax bill fight.
