Last May, Duerring reversed a decision Giles made not to let 21 graduating students walk during commencement.
Giles had banned the Capital students from the ceremony for what he called open insubordination after the students refused to take off the student-designed senior shirts. Giles objected to the shirts, which students say were meant to encourage school spirit, because they shortened the name of Capital High School to "Cap" and displayed a paw print rather than the school's cougar mascot logo.
In 2006, Giles booted between 50 and 70 students from Capital's prom because he said they broke the school's dance code. The following year, he had students sign a contract that forbade "dirty dancing" before they attended the prom.
But during the 2007 prom, students said Giles eased up, and relaxed the dancing policy in a surprising, late-evening announcement.
In 2011, Giles joined with parents and teachers in voicing strong opposition to making East Academy, an alternative night school housed at Capital High School, a day program.
Duerring said at the time that making East Academy a day program, where students in the alternative school would attend classes at the same time as Capital students, was only in the planning stages.
Kanawha school officials eventually housed the alternative program at the old Chandler Elementary School.
