In September 2014, a report was released by the American Institutes for Research on a three-year, quasi-experimental comparison of traditional and Deeper Learning schools. The research findings demonstrated the following improved student outcomes: students attending deeper learning network schools benefited from greater opportunities to engage in deeper learning and reported higher levels of academic engagement, motivation to learn, self-efficacy, and collaboration skills; students had higher state standardized assessment scores regardless of student background; students scored higher on PISA-based Test for Schools[28] on measures of core content knowledge and complex problem-solving skills; students graduated on time at statistically significantly higher rates (9 percent); and after graduation students were more likely to attend four-year colleges and enroll in more selective institutions.[29]
