But the United States is struggling to attract and keep teachers. The problem is most acute in rural areas, where kids may learn math from a social studies teacher. In urban schools, the teachers most likely to leave are black men, who make up just 2 percent of teachers. This APM Reports documentary tells two separate but connected stories about teachers that American schools desperately need but can’t hold on to: black men and those willing to work in rural areas.
