St. Paul Public Schools is reprinting report cards for close to 300 students after their first-quarter grades were misreported.

School district spokeswoman Toya Stewart Downey said teachers last week were given an extension on a deadline to input their grades, but report cards were printed before the final changes were made.

The district is mailing corrected grades to the homes of 252 students at Open World Learning and 39 at Murray Middle School, she said.

Stewart Downey said the district’s web portal, which also displays grades, was not affected by the error. Neither were students’ transcripts.

Quendy Raymond scolded her son Malachi, a sophomore at Open World Learning, when his report card showed a B instead of the A-minus he’d earned in chemistry. She’s upset the district made the mistake and didn’t tell parents sooner.

“Grades are a big deal in our house,” she said.
