Seneca Valley School District School Calendar 2026–2027

Seneca Valley students return Thursday, August 20, 2026. The June finish depends on grade: seniors have their last day and graduation Thursday, June 3, 2027, while K–11 students finish Friday, June 4. The following Monday, June 7, is an in-service day for staff. Families should use the separate student dates when arranging summer plans and confirm graduation details with the high school.

Thanksgiving time off starts November 25 and includes Monday, November 30, with classes resuming December 1. Winter holidays run December 23–January 1; students return January 4. The January 15 and 18 in-service days form a four-day student weekend. Spring holidays March 24–26 connect through the weekend to a March 29 in-service day and March 30 Act 80 day, so students are off March 24–30 and return March 31.

February 12, March 5 and April 16 are marked as snow make-up days. They become holidays if no make-ups are needed, so each requires a check before booking time away. The district can choose a traditional snow day or remote learning during weather closures. Act 80 and in-service dates mean no school for students; they are not remote-learning assignments.
