2017-18 Activities/Information CalendarPrint versions of the 2017-18 Activities/Information Calendar will be available at the beginning of the school year. To control postage costs, calendars are mailed only to those students in grades 7-12 who have no siblings in the K-6 grades. Students in grades K-6 will receive a calendar in their classroom during the first week of school. The activities calendar is an award-winning publication of the Seneca Valley School District Communications Department. All activities published were current as of August 1, 2017.
