As colleges increasingly understand the importance of intentionally engaging students, the field must turn to the game-changing challenge: "bringing high-impact practices to scale as part of a concerted effort to increase college completion rates." In an era of growing demand, shrinking budgets, and greater accountability, meeting this challenge requires singular focus. Colleges must make decisions--about every hour spent, every dollar allocated, every policy set, and every practice implemented--based on whether those decisions will make engagement inescapable for large numbers of their students. This is the second of three reports that are part of the Center's special initiative, Identifying and Promoting High-Impact Educational Practices in Community Colleges. The first report, "A Matter of Degrees: Promising Practices for Community College Student Success--A First Look" (ED529070) described preliminary findings about 13 promising practices in community colleges. This report looks at which of these practices appear to engage students effectively. These findings, along with those in the third report, "A Matter of Degrees: Practices to Pathways. High-Impact Practices for Community College Student Success," (ED561117) give colleges information they can use to focus resources on practices that are most likely to help more students complete college successfully.
