1) Are the Oxford Seminar courses worth the $1095.00 they cost? Some of the reviews I read say some of the teachers are not good, but I can't see a way to find out who the instructor is and if they are any good.
It sounds like ICAL Pete knows what he’s talking about, so I won’t go there. But you may want to consider an independent course, as they are easier to research and control. This is not to say that organizations like Trinity, CELTA or Oxford do not teach good methodology and classroom management, but they have a tendency to be cumbersomely bureaucratic and top-heavy.
2) Would I have a hard time finding work at my age?
Not in Mexico. Most schools love to have the world experience.
3) How handicapped am I by not having a four year degree?
Not much. The AA, combined with a TESOL course in Mexico, is more than enough to get you in the door of virtually any school in Mexico. Plus, you can do what I did and study online while you work.
4) How hard is it to find work within the US?
I have no idea, but I know that there are many junior colleges that offer
ESL classes to foreigners and these are state-subsidized programs. You may want to check them out.
5) Can I really learn what I would need to succeed in this profession in just six days? It doesn't seem possible. I mean, I realize that there would still be more to learn, but could I get a job upon completion?
I’ll have to say that I doubt it. It doesn’t sound like enough time to really get the teaching practice that you would need in order to successfully manage a classroom. Look for a course that has at least 100 hours of class and at least 6 teaching practice sessions.
Hope this helps!
