The Changing Face of the Teaching Force

Dr. Richard Ingersoll is a national expert on teachers—how they work, where they work, and why they work.

Dr. Ingersoll’s research sheds light on one of the largest and least understood professions in the United States. His work explores trends that have altered the face of the teaching force over the past three decades.

Since the late 1980s, the teaching force has ballooned in size, significantly outpacing growth in student enrollment. Yet teaching has largely grown to meet new needs—from special education to language instruction to more math and science high school teachers. The research gives insights into recent trends in teacher turnover, mostly created by a churn of new and minority teachers into and out of the profession. Today, the most common (or modal) teacher has just one to three years of experience.
