Now, you need that high school diploma in order to get a job, take classes here at GCC or at another postsecondary institution, for your own personal satisfaction, or to set an example for your children about the importance of education.  GCC is here to help. Our High School Equivalency Office assists individuals 16 years and older, who are not enrolled in a high school and who do not have a high school diploma, in obtaining a high school equivalency diploma by successfully passing either the GED® or the HiSET® high school equivalency test.
