Former Chairman Pedro Ramos, citing a family emergency, resigned his seat Oct. 21.
The governor, Eller said, "does understand the importance" of naming a replacement in a timely manner.
And while "a number" of official district actions - contracts and other legal documents - require a chairperson to sign off, "the absence of an SRC chairperson does not hamper the day-to-day operations of the district," said district spokesman Fernando Gallard.
Some of those official actions "are being placed on hold until we have an interim chair," Gallard said. "There are contracts that are waiting to be executed. But classrooms and schools are not being affected by this."
Who might replace Ramos, even on a temporary basis, has so far been a tightly held secret.
There is strong speculation, however, that Commissioner Feather Houstoun might become interim chair. Since any gubernatorial SRC pick requires confirmation by the state Senate, which likely won't happen immediately, a sitting SRC member is apt to be picked to lead the commission temporarily.
Houstoun is the only SRC member named by Gov. Corbett. The five-member panel has two mayoral picks, Wendell Pritchett and Sylvia Simms; Ramos was chosen by Corbett and the remaining member, Joseph Dworetzky, was selected by former Gov. Ed Rendell.
Houstoun on Thursday said that she had not been approached, and that she had not heard anything about the appointment of an interim chair.
Pritchett has presided over SRC meetings in Ramos' absence in the past, "and that works really fine," Houstoun said. "We just need someone to gavel."
"In the short run, it hasn't proved to be a problem," she said. "We haven't run into any significant legal issues."
Houstoun said that the four sitting SRC members, along with its staff, has handled administrative matters "by committee."
Monday's SRC meeting on "Options for Increasing Students' Access to Better Schools" will be held as scheduled, district officials said. No votes will be taken at that meeting.
