This article reports findings from a mixed-methods study of the impact of collaborations between adult education organizations and nonprofit or business partners on the earnings of program participants. The project uses survey data collected from a network of state-sponsored educational institutions and unemployment insurance data from program participants. Findings from the study emphasize that collaboration between adult workforce institutions and business, government, or nonprofit partners increases the earnings of adult training participants. The effects differ for men and women. These results were estimated using regression analysis, which related changes in quarterly earnings to two aspects of institutional collaboration: the intensity of collaboration and employer involvement.
