Durham's superintendent of schools says new exam requirements will cost the school system more than $100,000 a year. Durham Public School Superintendent Eric Becoats spoke Thursday about new exams required by the state. As part of North Carolina's Race to the Top plan, common exams will now be given in any subjects that are not already covered in a state-mandated exam. In the past, teachers whose classes were not part of a state test would administer their own exam. But now, the exams will look the same across the board, even for classes like physical education.
