As the Department of Education moves to close a record 62 schools for poor performance, officials on Wednesday released new numbers on what happened to students at the schools that closed last year.

For years, education advocates have been asking for information on where students go after a school officially closes its doors. Thanks to a new law passed by the City Council, the DOE was required to release those numbers. The data covers 15 schools that closed forever last June, four of them high schools.

The 569 high school students all should have been seniors, but only 48 percent graduated, with another 10 percent earning a special education diploma. Fourteen percent transferred to another school and 22 percent dropped out. The remaining high school students enrolled in a GED program or were discharged.

Those stats are worse than citywide averages: the graduation rate is 15 percent lower and the dropout rate twice as high. But DOE officials note that these schools actually did better in their final year than they had been doing before the city decided to phase them out.

On the steps of City Hall Tuesday, the elected officials most likely to run for mayor demanded this kind of information—specifically on how many students at closing schools are "lost" in the process. According to this new data, that answer seems to be about a quarter of the high school students and three percent of the elementary and middle school students.

Of the 14 percent of high school students who transferred, more than half ended up at a school with a low grade on the city's progress reports. Sixteen students actually went to another school that is in the process of closing.
