Although access to higher education is virtually universally available, college student retention stills remains a vexing and puzzling problem for educators and legislators. In College Student Retention: Formula for Student Success, second edition, Alan Seidman deals with this problematic issue by examining a number of areas critical to the retention of students, including the history, the theories and concepts, models, and a standardized definition of the term. Seidman and his contributors also lay out the financial implications and trends of retention in one of their updated chapters. Completely new to this edition are three chapters that examine several recent issues: the current theories of retention, retention of online students, and retention in community colleges. Tying all of these components together, Seidman then presents his formula and highly successful model for student success that colleges can implement to effect change in retaining students and helping them to complete their academic and personal goals.
