Team members of Project DEEP (Documenting Effective Educational Practice) spent almost two years immersing themselves in the daily work of twenty campuses. The common denominator of these institutions is that they all have participated in the National Survey of Student Engagement (NSSE) and have scored better than predicted across some or all of this survey's five benchmarks of effective educational practice: level of academic challenge, active and collaborative learning, student interaction with faculty members, enriching educational experiences, and supportive campus environment. To discover what these high-performing institutions are doing to add value to their students' experiences, Project DEEP team members reviewed hundreds of documents and Web sites and, in groups of three to five, conducted two multiple-day visits to each campus. In this article, the authors focus on one of the central qualities common to these twenty institutions: a widely shared sense of responsibility for educational quality and student success. Four conditions stood out: leadership, partnerships between academic and student affairs personnel, student agency, and what the team defined as "the power of one."
