As a foreign language instructor, your responsibilities revolve around working to teach students a foreign language. Your exact job duties depend on the needs, skill level, and age of your students. You instruct speaking, reading, or writing, though your focus may shift depending on your students. You may work on conversational skills and basic proficiency with the language or assist advanced students as they become fluent. You plan the curriculum for the class based on the goals of the students, the academic requirements of the institution (if any), and adjust lesson plans to address student needs.
