NEW ORLEANS- A case affecting funding for more than 30 Louisiana charter schools is set for arguments before the state Supreme Court.

Charter schools are tax-funded public schools operated by independent organizations under charters approved by state or local education officials. At issue in Tuesday's hearing is whether a group of charter schools that were granted authority to operate by the state's education board are getting money meant for local school districts.

The money is distributed to the districts through a formula approved each year by the Legislature. Some local education officials and a teachers union argued that sending any of that money to state-approved charters violates Louisiana's constitution.

An appeals court agreed in January, but has allowed the funding to continue pending appeals.
