Dr. Ingersoll's research is concerned with the character of elementary and secondary schools as workplaces, teachers as employees and teaching as a job. He has published over 100 articles, reports, chapters, and essays on topics such as: the management and organization of schools; accountability and control in schools; teacher supply, demand, shortages and turnover; induction and mentoring for beginning teachers; teacher preparation and teacher quality; the problem of underqualified teachers; the status of teaching as a profession; and changes in the demographic character of the teaching force.
