The Southern Teachers Agency, the oldest teacher-placement service in America, currently has several French vacancies listed by schools for the 2011-12 school year.  These jobs range from teaching French to elementary students through AP French Literature and Language courses.  For most PK-12 French positions, a bachelor's degree with a major in French (or at the very least a minor) is essential, but teacher certification is not.  Visit them at http://www.southernteachers.com
