Good Enough Diploma (“GED” backronym)

General Education Development (GED) tests offer an opportunity for a student to achieve a Certificate of High School Equivalency. The comedian Chris Rock wrote in his book Rock This! (1997):
 
“I dropped out of school. Sorry. I guess I’m not the best role model. Later, I got a G.E.D. You know what G.E.D. stands for? Good-Enough Diploma. A G.E.D. is bullshit.”
 
“Good Enough Diploma” is a backronym (back acronym) of “GED” that has been cited in print since at least 1996. “Good Enough Degree” is another backronymic nickname that has been cited in print since at least 1998.
 
 
Wikipedia: General Education Development
General Educational Development (GED) tests are a group of five subject tests which, when passed, certify that the taker has American or Canadian high school-level academic skills. The “GED” acronym is frequently misused to mean “general education degree” or “general education diploma,” when in fact the GED® brand was developed as a trademark to identify the “tests of general educational development,” a term coined by the American Council on Education, the owner of the GED trademark, in the 1940’s to identify a battery of tests that measure proficiency in science, mathematics, social studies, reading and writing. Passing the GED test gives those who did not complete high school the opportunity to earn their high school equivalency credential, but no state awards a GED per se. http://www.gedtestingservice.com/educators/history
 
The GED Testing Service, a joint venture of the American Council on Education and Pearson, is the sole developer for the GED® test. The test can be taken by paper or on computer, but tests must be taken in person. Jurisdictions award a Certificate of High School Equivalency or similarly titled credential to persons who meet the passing score requirements. Passing the GED® test therefore gives those who did not complete high school the opportunity to earn their high school equivalency credential.
