Closing low-performing New York City high schools helped students, according to a NYU Research Alliance report. Most of the middle schoolers who would have gone to the closed schools ended up at smaller, higher-achieving schools. Fifty-five percent earned a diploma in four years, compared to a 40 percent graduation rate for the now-closed schools.
A 2013 MDRC study found students attending smaller high-schools were 10 percent more likely to graduate on time than students at other schools, notes WNYC.
From 2002 to 2008, the city closed 29 large, low-performing high schools and opened more than 200 new, small high schools.
Post-closure students did better, but not well, researchers said. Fewer than half earned a Regents diploma.
