With calls for community colleges to play a greater role in increasing college completion, promising or high-impact practices (HIPs) are receiving attention as means to foster persistence, degree completion, and other desired academic outcomes. These include learning communities, orientation, first-year seminars, and supplemental instruction, among many others. This volume explores the latest research on: * how student success program research is conceptualized and operationalized, * evidence for ways in which interventions foster positive student outcomes, * critical inquiry of how students themselves experience them, and * challenges and guidance regarding program design, implementation and evaluation. This is the 175th volume of this Jossey-Bass quarterly report series. Essential to the professional libraries of presidents, vice presidents, deans, and other leaders in today's open-door institutions, New Directions for Community Colleges provides expert guidance in meeting the challenges of their distinctive and expanding educational mission.
