The current paper used data from the Wabash National Study of Liberal Arts Education-a longitudinal, pretest/posttest design-to estimate the effects of participation in the ten ''high-impact'' educational practices put forth and endorsed by the Association of American Colleges and Universities (AAC&U) on a variety of liberal arts educational outcomes. The high-impact practices included in the study were: first-year seminars, academic learning communities, writing-intensive courses, active and collaborative learning, undergraduate research, study abroad, service learning, internships, and capstone courses/experiences. Findings from ordinary least squares regression analyses suggested that active and collaborative learning as well as undergraduate research had broad-reaching positive effects across multiple liberal arts learning outcomes, such as critical thinking, need for cognition, and intercultural effectiveness. Several other high-impact practicesincluding study abroad, internship, service learning, and capstone course/experience-had more narrowly focused positive effects on student learning. Overall, this study's findings support AAC&U's advocacy of high-impact practices as pathways to student success.
