The job duties of a Portuguese teacher involve teaching students to speak, read, and write the Portuguese language. As a Portuguese instructor, you can teach in a high school, college, or other language schools. You can even work online in a virtual classroom. Your responsibilities typically include preparing a syllabus for each class, working with students to improve their Portuguese language abilities, and, when necessary, taking steps to translate learning materials. Depending on who you teach, you may focus on specific aspects of the Portuguese language and culture or provide general instruction to help students improve their overall skills.
