St. Mary’s Grade School, for the most part, follows the Harrision County Public School Calendar and Bus Schedule. Parents are notified when there is an interruption in the regular school schedule. In the case of inclement weather, parents are to listen to the local radio and/or TV station for news of school cancellations. If the Harrision County Schools ARE NOT in session, St. Mary’s Grade School WILL NOT be in session either. In case school is dismissed early because of heavy snowfall or high water, you will be called by the School Reach mass communication system.
