First talk to the counselor at your school, but there are other options depending on your state. I was in California when I received my teaching degrees. I attended a state university for a BA in Liberal Studies (after politics and lots of problems) … I went to University of Phoenix to get my Master in Elementary Education with my preliminary credential. There is also other schools, like National, that will offer the same, quick, yet strong education to meet our goals. Beware that states are always changing for credentialing requirements, additional exams, make sure you check and have the latest information from a very credible source. Try not to listen to what others say, let it lead you on the path in the direction, but find your own answers. Good luck … there’s lots of hoop jumping in education … but it’s well worth it! 🙂

Depends to your passion in which subject & what’s your target e.g. some prefer to teach nursery, high school, college/Uni..

Professionally, it’s important to have a academic qualifications; thus it shows you’re well trained & equiped with basic requirements of a teacher. Min. Masters in Education & if you prefer to specialize in a special subject e.g. maths, english etc. thn you’ve to get those Certs. in it. Depends to your country & state; they’ve difference names for it. You can search for more info. via your school’s academic assistant/counselor or even School Dean on this matter so you can transfer your A-Level credits & arrange for better options for you.

A school is only as practising ground, once you’ve done your internship/traineeship as a teacher thn only you’ll be qualified as a real teacher in most schools.
