I'm getting my bachelor's in Communication. I had heard that, for instance, if you wanted to get an MAT and be certified to teach English or Social Studies, your English and Social Studies courses would be built into the requirements for the MAT degree. But, at Kent State at least, it appears to be an entirely separate (and quite substantial) core of courses that must be completed prior to entering the program.
In other words, I'd heard that the MAT was designed for folks who didn't necessarily major in Education, and/or the field they want to be certified in, for their undergrad, but that appears not to be the case, at least in terms of Kent's program.
