The most common career path is to major in French at the undergraduate level, followed by a Master’s program in education. The school that I went to actually allowed me to do both at the undergraduate level, though I didn’t actually receive a degree in education. My degree was in Romance Languages, with a concentration in secondary education. In my last year of college, I did one semester of observation at the high school level, and one semester of full-time student teaching at the middle school level. Before finding a full-time position, you might try tutoring, giving private lessons, or even teaching English in France (there is a French government sponsored program for recent American graduates).
