Um, yeah, typically. I've never known a teacher whose degree wasn't a Liberal Arts degree. The term "Liberal Arts degree" covers bachelor's degrees in a very wide variety of subjects. It simply means that their education encompasses a wide variety of subjects, social sciences, history, humanities, philosophy, science, literature, language, etc., as opposed to a very specific degree where you study very few subjects unrelated to your specialty. The idea of the liberal arts degree was to provide graduates with a well rounded education. Degrees in education degrees are Liberal Arts degrees, however, all that was needed to substitute teach when I was in Michigan was to simply have a bachelor's degree.
