PHILADELPHIA (CBS) — A dozen Philadelphia charter schools earned new terms, but the School Reform Commission has turned thumbs-down on renewing two others.

Twelve schools, five of them Mastery Schools, were granted new five-year charters. But the School Reform Commission voted not to renew the charters of Delaware Valley Charter High School and the Universal Bluford School. SRC Commissioner Bill Green noted the poor academics at Delaware Valley.

“If you can’t get it right in 15 years,”Green said, “I don’t believe you deserve another term.”

Delaware Valley CEO Ernest Holiday is asking parents to remain patient.

“I’m asking them to stay the course,” Holiday said, “because we will be open in September and we feel we will be vindicated once we get our day in court.”

The charters are allowed to remain open while they appeal the non-renewal decision.
