The idea that a proposed constitutional amendment giving the state power to create charter schools would siphon money away from struggling public school districts, promote private institutions and disperse funds to schools with low academic standards is touted often by the measure’s opponents.

Rather than being afforded money that belongs to the school districts, charter supporters say the schools would receive funds they deserve.
