Jessica Jentis fit the profile of a typical American teacher: She was white, held a master's degree and quit 2 1/2 years after starting her career.
According to a new study from the National Education Association, a teachers union, half of new U.S. teachers are likely to quit within the first five years because of poor working conditions and low salaries.
The proportion of new teachers who leave the profession has hovered around 50 percent for decades, said Barry A. Farber, a professor of education and psychology at Columbia University in New York.
The study, which the association released last week ahead of its annual salute to teachers today, also found that the average teacher is a married, 43-year-old white woman who is religious.
Teachers are more educated than ever before, with the proportion of those holding master's degrees increasing to 50 percent from 23 percent since the early 1960s.
