Seaton Valley High School
Seaton Valley High School is a coeducational upper school and sixth form located in Seaton Delaval in the English county of Northumberland. Until 2025, it was called Astley Community High School.
It is a community school administered by Northumberland County Council, and admits pupils from Seaton Valley, particularly those graduating from Whytrig and Seaton Sluice Middle Schools. In September 2025, a new relocated campus was built in the north of the town on Prospect Avenue as a shared campus with Whytrig Middle School. The name of the school was changed from Astley Community High School to Seaton Valley High School.
Seaton Valley High School offers GCSEs and BTECs as programmes of study for pupils, while students in the sixth form have the option to study from a range of A-levels and further BTECs. The school also offers the Duke of Edinburgh's Award programme.
