In this 2013 Rand Corporation survey, researchers analyzed the association between correctional education and recidivism reductions, post-incarceration employment, and learning in math and reading. Their findings show that educational programs did in fact reduce recidivism rates as well as increase the odds of an offender finding post-release employment.
The study also looked into the cost effectiveness of correctional education as while as which types of education were the most effective. They found that programs can be cost-effective when considering recidivism, and that computer-assisted instruction led to a slight increase in reading comprehension and a substantial increase in math skills when compared to programs that did not use computers.
