An increasing number of states are offering alternatives to the GED in order for individuals to earn their high school diploma equivalency, a necessary prerequisite to earning two-year and four-year degrees in the United States. Check to see if your state allows students to complete the HiSET or TASC in order to earn your high school diploma equivalency. Also, unlike the GED, the HiSET and TASC can be completed on a computer or on paper.
