Canyon del Oro High School's reign as Academic Decathlon national champion has been annulled.

Citing a newly corrected scoring error, United States Academic Decathlon concluded Tuesday that CDO placed second in its medium school-sized Division II category. Ohio's Willoughby South High School is the division's national champion.

Because of the scoring error, USAD mistakenly awarded CDO the national title April 27 in Minneapolis. Officially, CDO placed second.

Division II schools have fewer than 2,200 students. CDO, at 25 W. Calle Concordia, is in the Amphitheater Public Schools district and has 1,582 students.

CDO math teacher Chris Yetman, 48, who coached the nine-student team, said the squad was disappointed with the result after USAD informed the team of the change in what he described as a "dispassionate" email.

"Everyone is very upset, They felt like it wasn't handled well," Yetman said. "The announcement wasn't handled well. Really, in a competition of this magnitude there shouldn't have been a mistake in the first place."

Yetman said a math error in an academic competition was "kind of an irony."

"Second place in the nation isn't bad, either," Yetman said, "but it certainly doesn't have quite the bragging rights of national champions."
