Mayor Bloomberg's quest to keep City Hall in charge of the city's public schools got a significant boost this morning when Assembly Speaker Sheldon Silver praised mayoral control as a good system.
"Nobody wants to go back to the old system of community schools," he said.
Silver's support comes just a week after his district's community board voted overwhelmingly to eliminate mayoral control.
His backing could be a crucial in convincing the Democratic-controlled Assembly to sign off on the plan, which expires in June.
Silver, who spoke to reporters after the Downtown Lower Manhattan Association breakfast, said he would like changes in the current system to accommodate more parental involvement.
"This is a good system in place. It could ultimately be made better without losing the principals for which it was originally contemplated," he said.
