COLUMBUS, Ohio (AP) – State Auditor Dave Yost is calling for changes in how Ohio pays its online charter schools.

Yost, a Republican, says how much a student learns should be part of the funding structure. He made the pitch Thursday at a charter school summit he’s hosting in Columbus. The two-day event provides training opportunities, tips for record-keeping and best enrollment practices.

The summit comes as state lawmakers have strengthened reporting, accountability and transparency requirements for charter schools. Those changes followed a scandal at the state’s charter-school oversight office, persistent performance lags and attendance irregularities.

Yost says the Legislature should review the funding of online charter schools when they return to session this fall.

He says changes are needed because it’s difficult to measure whether students are adequately participating in virtual instruction.
