The commission's next regularly scheduled meeting is in August, and angry charter school advocates had circulated e-mails, made phone calls, and mobilized supporters to turn out for Wednesday's meeting to urge the SRC to consider their requests so they could be ready for fall.
But Superintendent Arlene Ackerman insisted that the commission had planned to vote on the charter renewals as planned Wednesday.
"It wasn't a course correction," she told Mannella. "The SRC never, ever directed the staff that this vote was not going to take place on June 16."
After the SRC meeting, Benjamin W. Rayer, who oversees the district's charter office, denied that he had told charter officials in a conference call Friday that the SRC planned to delay voting and took responsibility if there was a misunderstanding.
Charter officials said their own efforts had led to the vote.
"Through a lot of efforts, including through our coalition, we were able to impress upon the staff and the SRC something had to happen" Wednesday, said Guy Ciarrocchi, executive director of the Pennsylvania Coalition of Public Charter Schools.
Saying they were trying to balance the charters' needs with the district's finances, the SRC authorized an increase of 1,042 charter seats for the 2010-11 academic year.
The vote was 4-1, with Johnny Irizarry voting no. He said he disagreed with how the district had selected some expansions to relieve overcrowding.
Michael J. Masch, chief business officer, said that the expansion would cost the district $7.3 million, but that the amount was included in the $2.3 billion budget the commission approved in May.
If the commission approved all 9,262 additional seats over the next five years that charters had requested, the five-year cost would be $266 million, he added.
