Noting that far more students attend charter schools in Philadelphia than are enrolled in the state's second-largest school district, a group has formed to represent city charters.
Founders of Philadelphia Charters for Excellence say they want to publicize the successes of charter schools and reassure the public that most of the 74 charters are not being investigated for possible corruption.
The organization requires member schools to meet strict ethical standards and plans to create a website to help parents compare the performance of charter schools.
The nonprofit organization was scheduled to be announced Friday.
"There are 74 of us, and in a typical school district with 74 schools, there would be a public-relations representative," said Jurate Krokys, chief executive officer of Independence Charter School in Center City and the group's vice president. "The idea is to be a resource about charter schools in Philadelphia."
The group's mission statement calls it "an alliance of high-performing public charter schools committed to creating a path toward academic and personal excellence for all students."
