Parents of Sun Prairie High School students might want to double check before affixing a "My kid's an honor student" bumper sticker to the family car.

More than 600 Sun Prairie High School students inadvertently made the third-quarter honor roll after a clerical district employee used the wrong grade-point average to calculate the list.

"We should have had 694 students that were listed as making the honor roll," said Sun Prairie High School Principal Paul Keats. "Because of the mistake we had 1,339 that were listed."

A 3.2 GPA is needed to make the cut. But the list that was published in last week's Sun Prairie Star included everyone earning a 2.0 or better (a C average). That meant four out of five students qualified.

A concerned community member at the district's Education and Policy Committee questioned the list at a meeting Monday.

"It was an unintentional human error and not a problem with our student record system," Keats said in an e-mail sent to district officials Tuesday.

The corrected list will be published in next week's Star, managing editor Chris Mertes said.

"We thought (the list) was unusually long, but they haven't been wrong in the past, so we had no reason to wonder," he said.
