This article critically questions where public school teachers go when they leave the teaching profession. It reviews the research to find that few studies appear to explain what occupations former experienced teachers ("leavers") move to. The article draws evidence from National Center for Education Statistics (NCES) data sets and publications to answer this question. NCES's data analyses of teacher mobility suggest only about 8 percent were "leavers" and were disproportionately male. The authors' analysis from the 1993-2003 NCES Baccalaureate and Beyond Survey suggests that among the few public school teachers who left teaching for another occupation, most took employment within other education occupations, including non-teaching positions in school districts and higher education. Nearly half that number started their own businesses in social organizations similar to public education. Fewer acquired education-related jobs in state or federal government employment.
