Helen Zelon of “City Limits” wonders why teacher turnover is so high in nyc charter schools.

She writes:

“According to data from the New York State Department of Education, charter schools in New York City lose far more teachers every year than their traditional school counterparts. In some schools, more than half of faculty “turn over” from one school year to the next, according to NYSED school report cards.

“Charter advocates at the New York City Charter School Center and at Success Academies, the city’s largest charter network, say that at least some of the turnover is due to movement within school networks—teachers moving up the leadership ladder, for example, or to seed the faculty of new schools, which have opened at a rapid clip in recent years.

“But even so, it’s hard to explain a churn of more than half the veteran faculty, which is the case at 15 percent of charter schools for which the state reports data….”

“The situation is not much better for veteran teachers, who are often the minority in charter schools: Of the 70 schools, 10 lost more than half of their veteran faculty in the ’11-’12 academic year; 24 schools saw more than 40 percent of experienced teachers exit.”

Zelon adds:

“Near the top of the turnover chart is the Success Academies system led by former Councilwoman Eva Moskowitz. With 22 schools and 10 new schools opening in August 2014, it is the city’s largest charter chain.

In Harlem Success Academies 1-4, the only schools for which the state posted turnover data, more than half of all teachers left the schools ahead of the 2013-14 school year. In one school, three out of four teachers departed.”

Spokespersons for HSA said the data were wrong.

Why is attrition so high? Long working hours; teacher burnout; TFA who made a two-year commitment and never intended to stay longer.
