High turnover at charters

Teacher turnover is up to three times higher at Los Angeles' charter schools than at traditional campuses, even while student enrollment continues to grow at the independently run campuses, according to two studies. Connie Llanos in the Daily News.

Researchers at the University of California at Berkeley tracked traditional and charter campuses within Los Angeles Unified's attendance boundaries between 2002 and 2009 - a time when the number of charters soared from 53 to 157 campuses.

They found that teachers at elementary charter schools had 33 percent higher odds of leaving by year's end than their peers at traditional campuses. The odds of leaving soared to nearly four times for charter teachers at middle and high schools, the study found.
