How did you know what grade level you wanted to teach? I'm waffling over whether to go for a multiple subjects credential or an English single-subject credential. Since they are both in pretty low demand, there does not seem to be any economic reason to choose one over the other. I always thought I'd go for English, but lately I keep thinking about how much I like that upper elementary age group as well as the idea of working with the same group of kids all day. On the other hand, I'm good with teenagers, and I majored in English and love the subject matter. So, how did you decide? And, on a related note, is it difficult to switch once in the field?
