Parents of students in the Region 15 School District are criticizing the school board for a lack of transparency after Superintendent Josh Smith’s DUI arrest last month. Police say Smith crashed into a pole and a parked car in Southington on January 18, with tests showing he was over the legal limit. The board acknowledged the arrest only after it was reported by the media. Some parents say Smith should have been placed on leave, while the board says it still supports his leadership.
