It's a statistic that's sure to surprise: close to 45 percent of postsecondary students in the United States today do not enroll in college directly out of high school and many attend part-time. Following a tradition of self-improvement as old as the Republic, the "nontraditional" college student is becoming the norm. Back to School is the first book to look at the schools that serve a growing population of "second-chancers," exploring what higher education--in the fullest sense of the term--can offer our rapidly changing society and why it is so critical to support the institutions that make it possible for millions of Americans to better their lot in life.
