FORSYTH COUNTY — Following an executive session Thursday night, the Forsyth County Board of Education approved the opening of four principal positions within the school system. North Forsyth High’s Beth Hebert is set to transfer to director of human resources, said Jennifer Caracciolo, a spokeswoman for the district. Principals Rebecca Johnson of Shiloh Point Elementary and Connie Stovall of Little Mill Middle will move to the administration’s teaching and learning department. All three transfers will take effect June 1. Kathy Rohacek, Vickery Creek Middle’s principal, is retiring June 30. Caracciolo said the goal is to have the spots filled in February. The district began accepting applications in late 2014 for general principal postings, as she said it does each year.
