Several Prince William County teachers, some of whom were placed on administrative leave, will have to undergo retraining after giving students inappropriate help on state-mandated exams, and students were required to retake tests, according to a school official.
County schools spokesman Phil Kavits said the teachers, who were supposed to interact minimally with students during testing in the spring, were overzealous in offering assistance
Twenty-eight students had to retake tests, Kavits said. He could not say exactly how many teachers were involved.
The testing problems were first reported Tuesday in the Washington Examiner.
