GED® High School Equivalency Certificate

The GED® test is a national test that may be taken in California by persons who are eighteen years of age or older, or who meet specific criteria for testing at age seventeen. The GED® test is administered statewide throughout the year at approximately 190 testing centers. Topics tested on the GED® include language arts/reading/writing, mathematics, science, and social studies. The GED® test is for adults who do not have a high school diploma. Those who pass the test receive a High School Equivalency Certificate.

Those who pass the test receive a GED® certificate and an official report of test results from the State of California. Additional information is available on the California Department of Education (GED)® web site.

Columbia College is no longer offering GED Testing Services or GED Preparation courses on site. We are partnering with Adult Education providers in our community to provide adult dual enrollment for those who wish to take college courses and seek their Diploma/GED (CAST). For those looking for  GED Testing or GED Prep, the list below will assist in connecting you with community partners in your county of residence.
