"Project QUEST" ("Quality Employment through Skills Training") provides comprehensive support services to help participants complete occupational training programs at local community colleges and professional training institutes, pass certification exams, and obtain well-paying jobs in targeted sectors of the local economy. This What Works Clearinghouse™ (WWC) report, part of the WWC's Postsecondary Career and Technical Education topic area, explores the effects of "Project QUEST" on education and labor market outcomes. The WWC identified five studies of "Project QUEST." Three of these studies meet WWC standards. Findings on "Project QUEST" from the three studies that meet WWC standards are shown in the table featured in this Snapshot. The table reports an effectiveness rating, the improvement index (a measure of the intervention's effect on an outcome), and the number of studies and students that contributed to the findings.
