More than 160 schools statewide, including nearly half of Tulsa's Public Schools, are failing under the current A-F grading system.
The statewide A-F grading system is designed to give parents more power by allowing them to see how their child's school is performing, but several superintendents and teachers say the new report card system is "unfair."
Republican State Superintendent candidates Janet Barresi and Joy Hofmeister had two different opinions on the system during Tulsa's Channel 8's State of Education Debate.
Hofmeister attacked the system and called it flawed.
"A-F grades don't give accurate information," Hofmeister said. "How do we trust someone who uses something we know is not stable? The A-F system needs to be fixed. We cannot give false information and say that it's accurate."
Incumbent Barresi defended the system that was implemented on her watch.
"Administrators that don't like accountability, don't like the A-F grading system," she said.
"We are proud of the A-F grading system and the change it has brought about."
