BROOKLYN - Parents, administrators and other charter school advocates held a rally at Borough Hall Thursday in favor of a state Senate proposal to provide funding.

A state Senate proposal would continue to provide funding for all charter schools and guarantee co-location in public buildings. 

Advocates are calling on the state Assembly to support the plan as well.

The rally comes in the wake of Mayor Bill de Blasio canceling the co-location of some charter schools in the city. Parents are worried that future charter schools will be in jeopardy if the state does not step in. 

In a statement, the mayor's spokeswoman said, "We took the best possible path forward, rejecting those proposals that did not meet our values and [working] with school communities on those proposals that could be implemented responsibly."

However, the city says 14 out of 17 charter proposals have been approved to open next school year.
