Adult vocational training

Evidence Rating  
Scientifically Supported
Evidence rating: Scientifically Supported

Strategies with this rating are most likely to make a difference. These strategies have been tested in many robust studies with consistently positive results.

Health Factors  

Vocational training for adults supports acquisition of job-specific skills through education and certification programs, also called career and technical education, or on-the-job training. Programs may include job search assistance, personal development resources, and other comprehensive support services (e.g., child care) during training. Some programs provide participants with financial compensation for the duration of their participation. Vocational training programs in the United States usually serve individuals with little job experience or education, individuals who are unemployed, or dislocated workers.

Expected Beneficial Outcomes (Rated)

  • Increased earnings

  • Increased employment

Other Potential Beneficial Outcomes

  • Reduced recidivism

Evidence of Effectiveness

There is strong evidence that vocational training for adults increases employment and earnings among participants, including young adults and unemployed individuals1, 23, 4, 5, 6, 7, 8, 9, 10, 11, 12. Vocational training can help dislocated workers regain employment, but does not consistently lead to full wage recovery5, 8, 10.

Participants increase employment4, 9, 10 and earnings more than non-participating peers following program completion14, 9, despite frequent initial reductions in earnings during the training and education period. In some cases, earnings increase even when participants do not complete the program1. An assessment of the California community college system’s vocational degree and certificate programs indicates larger increases in earnings among graduates with degrees and certificates in the health care sector than graduates in other fields3. An assessment of Project QUEST, an initiative that funds health care sector training and provides comprehensive supports, demonstrates increases in participants’ earnings and financial stability in the long-term2

Job Corps, a widely implemented vocational training program for young adults that includes comprehensive support services and financial compensation, appears to increase participants’ earnings, employment, and education two years after program completion11, especially among those who complete a GED program12. Over the longer term, however, most participants’ earnings are similar to non-participating peers, except for those who were 20-24 years old when they enrolled. Job Corps also appears to reduce arrest and incarceration rates among participants11.

Comprehensive vocational training programs appear to be more effective than less comprehensive programs; an evaluation of Jobstart, based on the Job Corps model but without comprehensive support services and financial compensation, demonstrates no effects on employment or earnings13. Researchers suggest that program implementers provide workers with structured guidance in training selection, and supportive services within training once they have enrolled. Developing training programs in partnership with local employers is also recommended to ensure workers are trained in in-demand skills14.

Vocational education and employment programs for individuals who have been incarcerated may reduce recidivism15. Stringent state-level work policies implemented with welfare reforms in the 1990s appear to have reduced vocational education and training opportunities for mothers with low incomes and low levels of education16.

Impact on Disparities

Likely to decrease disparities

Implementation Examples

Government-sponsored vocational training programs exist throughout the country. The Department of Labor’s (DOL’s) Job Corps has training centers in all 50 states, Washington DC, and Puerto Rico17, and the US Department of Health and Human Services (US DHHS) funds a variety of health profession-specific programs in 21 states18. However, federal appropriations for DOL job training grants decreased by 40% from 2001 to 2017, and Department of Education grants that support career and technical education in community colleges, technical schools, and high schools decreased by 34%19.
