- The GED test is taken to demonstrate a level of knowledge equivalent to that of a high school graduate. In order to pass and be awarded a GED certificate, a person must receive a score higher than 40 percent of high school graduates. The GED test offers those who do not have a high school diploma an alternate route to higher education and a credential for employment. This is of particular importance for those who cannot simply return to high school. Most public schools prohibit this once a certain age has been reached.
- The GED test consists of five parts used to measure knowledge and mastery of reading, writing, mathematics, social studies and science. The tests may be taken separately or together in a single day. The tests are primarily in a multiple choice format but the writing test includes an essay. Typically, a person must score at least 410 out of 800 on each section of the test to pass, with an overall average of at least 450. Individual failed tests may be retaken but in most states there is a limit on how many times a test may be attempted.
- The GED should not usually be considered as an alternative to a high school education. Instead, it offers an opportunity for those who cannot return to high school and people who were home schooled but want an official certificate to prove their educational level. The GED test cannot be taken before age 16, and in some states the minimum age to take the test is 18. Holding a GED certificate is not entirely equivalent to having a high school diploma--some employers are less likely to hire people who have a GED and colleges sometimes decline students if they do not have a high school diploma.
- Holding a GED certificate greatly improves access to entry level employment in most professions. As a result, people who have a GED typically have a substantially higher income than those who have no educational credentials. A GED certificate is usually considered equivalent to a high school diploma when enrolling in advanced training and certificate programs. Although not all colleges accept GED holders, most community colleges do. This creates a path to higher education.
- During World War II, many young men enlisted in the armed forces before completing high school. In response to the needs of returning veterans, the first GED test was released in 1942; it was intended to give military personnel an opportunity to demonstrate their mastery of high school level skills. The test has undergone major modifications three times since the original release--in 1978, 1988 and 2002.
