HARRISBURG — Most of Gov. Tom Corbett’s four-pronged education agenda for promoting alternatives to public schools and overhauling teacher evaluations remained on hold Friday night as Republican leaders tried to smooth out wrinkles in hopes of sending lawmakers home for on Saturday.

A closed-door GOP leadership meeting with Corbett bogged down over a bill to expand the state’s role in the regulation of charter schools. The Senate abruptly recessed for the night and the House followed suit. House Speaker Sam Smith declined to talk with reporters after the meeting.

Drew Crompton, chief of staff to Senate President Pro Tempore Joe Scarnati, R-Jefferson, declined to reveal details but said he believed the most serious disagreements involved the charter-school bill.

Crompton said Republican leaders have been working “day and night” and that flare-ups over the wide-ranging education package were to be expected.

“This is an incredibly large bucket of education reform,” he said.

Discussions about the charter bill continued behind the scenes.

The Republican governor originally called for creating a state panel that would authorize new charter schools, taking that power away from local school boards. But a Senate Republican summary of the latest proposal suggests that he’s unlikely to fully achieve that goal.

The proposal calls for transforming the present State Charter Appeal Board into a larger, independent panel whose jurisdiction would be limited to cyber-charter schools, regional charters involving more than four school districts, existing schools that transfer their charters to the state level and organizations that operate multiple charter schools.

Local school boards would continue to be the authorizers for charter and regional charter schools, although the state board would oversee appeals of charters rejected by the local boards.
