@Setanta,
I dont know how charter schools operate in other states other than Pa, NY, NJ, and Md. In thise states the Charter school LLC actually receives hlf of the perstudent stipend that the public schools get. The proviso is that the Charter SChool (CS) teaches and is mmeasured by state standards.
As weve found in PA, several of the LLCs are actually EVangelical churches. The LLCs are being watched carefully so that they dont become Jr "Liberty Colleges"
NOW, a parent (or three) would have to file a suit ala Dover for teaching issues that cross the wall in accordance with all the USSC and Fed District courts have decreed.
SInce the public schools get the other hlf of the money and dont have to put upwith the kids, they are happy.
