This study uses nationally representative longitudinal data and propensity score modeling to evaluate the effects of first-year engagement experiences at community college--including social and academic contact with faculty and participation in study groups and clubs--on achievement, persistence, degree attainment, and vertical transfer. Speaking with faculty about academic matters improved short- and long-term outcomes, while engaging in study groups and clubs improved early outcomes, with less sizeable long-term impacts. The findings highlight the need for continued inquiry into community college engagement using longitudinal data with detailed engagement and outcome measures to determine best practices.
