EDMONTON -- The principal at the centre of a school "no-zero" controversy has resigned and taken a new post with the Edmonton Public School Board (EPSB).

Ron Bradley announced his resignation from Ross Sheppard High School in a letter on its website, and the school board has confirmed he's been hired for a position in their Human Resources department.

"It is with mixed emotions that I inform you I will be leaving my principalship at Ross Sheppard School effective immediately," Bradley said in the undated letter addressed to parents.

"I want to thank you for the support you have shown me as principal the past five years."

Bradley was deeply embroiled in the no-zero controversy that swept the city and was largely responsible for the suspension and subsequent firing of physics teacher Lynden Dorval.

Dorval, a 32-year teaching veteran, was fired for disobeying school policy when he gave zeros to students who failed to complete assignments.

Bradley had expressly forbidden Ross Sheppard teachers from handing out zeros. Instead, they were to make a note that the work had been missed.

Dorval continued to hand out zeroes because he considered it more detrimental to allow a student to "scrape by with mediocre effort."

"I keep saying I will never regret it," he told QMI Agency the day he was terminated. "If students don't do the work, they don't deserve the mark -- and I stand by that."

Bradley has since criticized local media for coverage of the issue that he alleges made Ross Sheppard "the poster child for every perceived illness of public education."

He will now serve as Supervisor of Leadership Development for the school board, EPSB spokesman Jane Sterling said Friday.

"Bradley applied for the position and was a successful applicant," she said. "He'll be responsible for the framework of leadership in our district."

After months of turmoil, Dorval has bounced back from his termination.

Recently he accepted a part-time physics position at Tempo School, a private kindergarten-Grade 12 school on the city's south side.
