PHILADELPHIA (CBS) — A prominent nonprofit is aiming to raise millions more to improve Philadelphia schools.

The six-year-old nonprofit Philadelphia School Partnership is launching a second round of fundraising to provide grants to Philly schools. Its first round provided $60 million to expand 45 schools — two-thirds of them, charters. PSP Executive Director Mark Gleason says round 2 aims to raise $60 million more.

“We’ve learned a lot in 6 years. So this new fund will have several areas of new emphasis, Gleason said. “This second fund gives us a chance to reload, but also to add emphasis in areas that proved to be important to the work we’ve done so far.”
