Instructor: Elizabeth Potter HiSet is Maine’s general education development (GED) program. If you are an adult without a high school diploma, the High School Equivalency Test (HiSET) program could be your route to improved career prospects, a college education and increased earnings potential. Adult diploma programs are central to the mission and tradition of Maine Adult Education. Get your diploma and be one step closer to achieving your life's goals! If you are unable to join us during the regular Adult Learning Center hours, we have an active tutoring program available via Zoom and can schedule 1:1 time with the instructor.
