"Career Academies" were developed more than 30 years ago as a drop-out prevention strategy and targeted youth considered most at risk of dropping out of high school. More recently, "Career Academies" have broadened the kinds of students they serve, consistent with efforts to integrate rigorous academic curricula with career themes and to attract students who are preparing for post-secondary education. The What Works Clearinghouse (WWC) reviewed seven studies of the effectiveness of "Career Academies." One study (Kemple & Snipes, 2000; Kemple, 2004) was a randomized controlled trial that met WWC evidence standards. The Kemple and Snipes (2000) and Kemple (2004) study was a randomized controlled trial that included a total of 1,764 students who applied to the entrance grade (9th or 10th) of nine "Career Academies" included in the evaluation. Of these, 474 students were predicted to be at high risk of dropping out of high school. The study measured outcomes at the end of a student's projected 12th-grade year and then four years after a student's projected 12th-grade year. Based on this one study, the WWC found potentially positive effects on staying in school, potentially positive effects on progressing in school, and no discernible effects on completing school.
