GED certificate programs

Evidence Rating

Some Evidence

Health Factors

The General Education Development (GED) certificate is the primary educational credential for individuals who have dropped out of school or have arrived in the US without a credential equivalent to a high school diploma. Attendance at any particular course or training program is not required to obtain a GED. Instead, an individual must pass a series of tests. Passing the GED test certifies certain levels of general knowledge in mathematics, writing, reading, social studies, and science (Tyler 2005). GED programs are sometimes combined with counseling and social services (MDRC-Bos 2002).

Expected Beneficial Outcomes (Rated)

  • Increased earnings

  • Reduced recidivism

Other Potential Beneficial Outcomes

  • Increased GED certificate completion

Evidence of Effectiveness

There is some evidence that GED certificates increase earnings for individuals with low cognitive skills and adults who use their GEDs to obtain post-secondary education (NBER-Heckman 2010Tyler 2005). GED receipt through correctional education programs reduces recidivism and may increase employment for individuals who have been incarcerated (Urban-Gaes 2008, RAND-Davis 2013). Other recipients, such as youth transitioning out of foster care (), are less likely to realize earnings or employment benefits (NBER-Heckman 2010Tyler 2005). Additional evidence is needed to confirm effects.

It often takes several years of post-GED work experience for recipients’ incomes to increase, and gains are typically modest (Tyler 2005NBER-Heckman 2010). Few GED recipients advance to post-secondary education, but those who do substantially increase their earnings (Tyler 2005NBER-Heckman 2010MDRC-Bos 2002). On average, GED recipients earn more than peers who do not complete high school and less than high school graduates (Tyler 2005); health outcomes for GED recipients are generally similar to individuals who do not complete high school, and significantly worse than outcomes for high school graduates (Zajacova 2014).

In some instances, bridge programs that use career-focused GED curricula to support the pathway from GED to college can increase GED receipt as well as college enrollment more than traditional GED programs (MDRC-Martin 2013). GED programs that use more rigorous college and career readiness curricula may also be more likely to encourage GED recipients to continue with post-secondary education and training (MDRC-Rutschow 2014).

Researchers recommend that GED programs help students manage adult responsibilities that can make program completion difficult, link to post-secondary programs, stress the necessity of further education, and help students navigate the post-secondary admissions and financial aid processes (Tyler 2005MDRC-Bos 2002, MDRC-Rutschow 2014). Research also suggests GED classes can increase receipt of GEDs regardless of participants’ initial level of motivation (MDRC-Bos 2002).

In some cases, GED access can induce potential high school graduates to drop out. Factors that decrease GED desirability such as high minimum dropout ages, more rigorous GED standards, or parental consent requirements are associated with higher rates of school completion. High school exit exams, conversely, may increase attempts to earn GEDs (NBER-Heckman 2010).

Impact on Disparities

Likely to decrease disparities

Implementation Examples

GED programs are available in all states, as well as online (Learning Path). As of 2012, approximately 1.62 million non-institutionalized, civilian 18-24 year olds had earned a GED (NCES-Stark 2015). As of 2010, only 16.8% of GED holders 18-29 years old enrolled in college (Sum 2012).

GED bridge to college and careers programs that support pathways for GED recipients to continue with post-secondary education and training are also becoming more available, for example, at LaGuardia Community College in New York (LAGCC-GED bridge) and at Northeast Wisconsin Technical College (NWTC-GED bridge).

YouthBuild programs combine academic preparation for the GED or other high school equivalency tests with hands-on job training to prepare students for post-secondary education or employment. As of 2016, there are 260 urban and rural YouthBuild programs available in 46 states (YouthBuild). Project Rise, which links GED preparation classes with case management and part-time, paid internships, operates in New York City; Newark, New Jersey; and Kansas City, Missouri. (MDRC-Project Rise).
