As a Spanish instructor, your responsibilities vary depending on the age group or skill level with which you work. If you work as a teacher in an immersion elementary school program, your duties include designing age-appropriate lessons and encouraging a Spanish-only environment for the kids. As a high school Spanish instructor, you may teach students who need to meet general education requirements. Your duties include designing or teaching to a specific curriculum, administering assessments, and grading class assignments. At the college level, you may teach basic conversational classes, advanced courses, and classes that introduce students to the complexities of the Spanish language, such as Spanish literature and translation.
