Training individuals who are at risk of unemployment/underemployment to increase their employability is a mission of many nonprofit agencies. These training programs, often supported by government funding, attempt to reduce these individuals' reliance on government assistance. The purpose of this study is to obtain hard data and an in-depth understanding about the factors that contribute to the success of the Green Construction training program. The methodology used is a multimethod, multimeasure approach, which provides a reasonably robust triangulation of results. The findings indicate that the program is successful because it has good participant retention, knowledge gain, and placement rates. (Contains 2 tables.)
