Four of five Philadelphia charter high school students now graduate within six years.
The on-time, four-year graduation rate was 76 percent for students who started high school in 2008 and graduated in 2012. That rate is the same as two years ago.
Charter school graduation rates have consistently exceeded District rates by 12 to 18 percentage points over the past five years. However, charter high schools overall educate smaller percentages of low-income students and special education students than District schools.
