The Edmonton Public School Board says it will review how students are graded after a teacher was suspended for refusing to stop handing out zeros to students who didn't complete their work.
The board has voted unanimously to launch the review, which will begin after the summer break. High school physics teacher Lynden Dorval is at the centre of the controversy.
His school has a policy of giving students an incomplete for assignments not handed in or tests missed, but Dorval refused to follow it.
