Maybe look at department of education in the states she is considering. The Peterson guides show ALL schools that offer a particular major in strictly alphabetical order (no matter if school is highly ranked or not). If a school has education as major you can then look at specifics. If you want to teach HS in my state, you could get certified by majoring in specialty area and minoring in education. You might be able to do 5th year masters depending on school but you’ll probably just have to look at each one you are interested in. Also look within major program. For instance, D is math major and one “track” is secondary education with specific math courses plus education coursework.
What part of country is she looking in? Maybe we can give you some ideas beyond state schools. For instance in SC, Furman offers education as major and offers 5th year masters (the only graduate degree it offers).
