“Even we set aside the nearly 50 percent of all beginner teachers who choose to leave the profession within five years—and ignore the evidence that those who leave are worse performers than those who stay—it is unclear whether teachers are formally terminated for poor performance any less frequently than are other workers.”

“Henry David Thoreau, Susan B. Anthony, W. E. B. DuBois, and Lyndon B. Johnson are just a few of the famous Americans who taught. They resisted the fantasy of educators as saints or saviors, and understood teaching as a job in which the potential for children’s intellectual transcendence and social mobility, though always present, is limited by real-world concerns such as poor training, low pay, inadequate supplies, inept administration, and impoverished students and families. These teachers’ stories, and those of less well-known teachers, propel this history forward and help us understand why American teaching has evolved into such a peculiar profession, one attacked and admired in equal proportion.”
