High teacher turnover rates are costing the District a lot of money.
Approximately half a million teachers either leave the profession or move each year, costing the U.S. more than $2 billion. That's according to a report from the Alliance for Excellent Education.
The teacher turnover rate disproportionately affects high-poverty schools and also has financial implications. In D.C. for example, the costs are estimated to be between $3 to $6 million.
According to the report, high-poverty schools experience a teacher turnover rate of about 20 percent each calendar year - roughly 50 percent higher than the rate in more affluent schools.
Teachers leave for a variety of reasons, including not enough support, poor student discipline, low salaries and not enough of a say over schoolwide decisions. Turnover is especially high among new teachers, with up to half of them leaving the profession after five years.
To prevent turnover, the report recommends mentoring, professional development and common planning times.
