A new study says that for every charter that opens, a Catholic school closes.
The author, Abraham Lackman, who worked for the New York state senate when it passed the first charter law in 1998, said that no one anticipated that charters–which are publicly-funded and tuition-free–would drain students from Catholic schools, which are not tuition-free.
He says the charters are not as good as Catholic schools and cost the state additional millions of dollars.
The head of the foundation that supports charters in Albany said that parents make the choice. “We’re more concerned with where they’re going, not with where they’re coming from,” he said.

so this is why Catholic churches in NC supports vouchers.
Yes, without vouchers, the Catholic schools will be killed off by charters. But with vouchers comes a risk of government regulation.
Well if the “regulation” resembles what we have for charters, there’s not much to worry about.
Charters and vouchers go together for just this reason. If your state has one, people are pushing for the other. Rest assured.
In Chicago, the politically connected UNO charter chain is rapidly draining Hispanic students from the Archdiocese schools. Vouchers are unpopular here and not in place.
I was told by those inside the Catholic system that vouchers will be almost matched by an equal increase in tuition. This will certainly be true at least in part.
Apparently the charter operators never asked themselves:
What would Jesus do?
They take over the Catholic school buildings!
It is interesting that charter schools are seen as a substitute for catholic schools by parents but traditional public schools were not seen as a substitute. Does anyone have any insight into why that is the case?
