America’s vanishing teachers

More than a third of America’s 3.2 million teachers could retire within
the next 4 years, according to a report from the National Commission on
Teaching and America’s Future. Within the next 10 years, more than half
– 1.7 million — could leave teaching. What’s going on? The ageing of
the teaching profession. More than half of American teachers and
principals are Baby Boomers.
