As an online GED instructor, your duties are to prepare students to take the GED exam, which stands for general educational development or general education diploma. The GED exam is for students who want to get their high school diploma but are no longer in school. This may include people who dropped out and want to return and those who are in prison. Online GED instructors typically work on virtual platforms over the internet where their responsibilities are to teach modules, lead discussion sessions, administer practice exams, and provide extra help for those preparing to take the exam.
