Jessica Jentis is a typical American teacher; She was white, held a master’s degree and quite two and a half years after starting her career.
According to a new study from teachers’ union the National Education Association, half of new US teachers are likely to quit within the first five years because of poor working conditions and low salaries.
Jentis, now a stay at home mother of three, says that she couldn’t make enough money teaching in Manhattan to pay for her student loans.
“The kids were wonderful to be with, but the stress of everything that went with it and the low pay did not make it hard to leave, ” she said. “It’s sad because you see a lot of teachers the are young and gung-ho(雄心勃勃的) are ready to leave.”
The rate of new teachers leaving has reached as high as 50 percent for decades, said Barry Farber, a professor of education and psychology at Columbia University.
The study, which the association released last week, ahead of its annual salute to teachers on Tuesday, also found today’s average teacher is a married, 43-year-old white woman who is religious.
Teachers are more educated than ever before, with the rate of those holding Master’s degrees increasing to 50 percent from 23 percent since the early 1960s.
Only 6 percent of teachers are African-American and 5 percent are His panic, Asian or come from other ethnic groups. Men represent barely a quarter of teachers, which the association says is the lowest level in four decades.
“We must face the fact that although our current teachers are the most educated and most experienced ever, there are still too many teachers leaving the profession too early, not enough people becoming teachers and not enough difference in the profession,” said NEA President Reg Weaver in a statement.
Thanks to the high dropout rate of younger teachers, there will be plenty of job openings for teachers over the next 10 years, according to the Bureau of Labor Statistics.
Because education is governed at the state level, programs to retain (留住) younger teachers differ from state to state.
56.The first paragraph is written to _______. ( )
A. introduce the reason of the teachers’ being out of work
B. tell us the woman teacher has received a good education
C. introduce the topic to be followed D. tell us something about the teachers
