YouthBuild is a “second chance” program for young people. Targeted largely to high school dropouts, YouthBuild is a federally and privately funded program that provides construction-related training, educational services, counseling, and leadership development opportunities to low-income, out-of-school youth ages 16 to 24. The evaluation included 75 existing YouthBuild programs who received funding from DOL or the Corporation for National and Community Service in 2011. The evaluation included an impact analysis (with 72 sites), process study (all 75), and a cost analysis (58 sites). Overall, the impact study includes 3,929 sample members. Three sites were unable to contribute sample members to the impact study; among the remaining sites, the study sample size varied considerably from 250 to 9. (Twenty-three sites have 25 or fewer study participants.) The main impact analysis drew on three waves of survey data and two administrative records sources and pooled data across all sites. A program features analysis used the extensive implementation research data to investigate how impacts might vary based on site-level characteristics.
