Increasing education among low-income parents is a vital component of policies to improve families' economic status. Educational attainment matters: between 1979 and 2005, wages for those with college and advanced degrees rose by 22 and 28 percent, respectively, while wages for high school graduates remained stagnant and wages for high school dropouts fell by 16 percent. Moreover, the strong association between postsecondary education and higher earnings does not necessarily mean that facilitating access to higher education among low-income adults will lead to earnings gains, particularly considering that many lack recent or successful school experiences. This brief draws on rigorous studies to highlight what is known about efforts to encourage participation in and completion of postsecondary education among recipients of Temporary Assistance for Needy Families (TANF) cash assistance and other low-income populations. In this brief postsecondary (or higher) education is defined as academic and vocational/occupational postsecondary programs but not basic education (such as GED preparation classes or high school diploma programs). The brief explores the programs that have been tried, their success in increasing engagement and completion, and the extent to which increases improved economic well-being.
