I was just wondering what it takes to teach at a college/university level. It seems a doctorate in a field is a must, but I was wondering about experience "requirements". For example, is previously teaching at a high school or secondary school not necessarily required, but suggested? Do teaching licences cover the university level? I suppose there are different kinds of licences for different levels... What I'm trying to get at is that I do want to teach at the university level someday, but I don't want to teach lower levels, if that's not enough of a paradox. Originally my plan was to teach elementary, or a lower level, while I study for masters/doctorate, then get the positition. The only reason I would teach a lower level is to support myself and pay for tuition, but I've been rethinking this; pondering whether I would have to teach at all before being able to hold tenure at a university.
