Scottish Borders Council has submitted a planning application for the new £21.8m Kelso High School.
The submission comes after a land purchase agreement between the council and land owners Lothian Estates for the ground at Nethershot on Angraflat Road was concluded in March.
Community drop-in sessions are expected in the coming months to provide updates on the project.
Councillor Sandy Aitchison, SBC’s executive member for education, said: “The submission of the planning application brings a new Kelso High School another step closer.
“With a land purchase agreement already in place, I am pleased to see the project progressing and look forward to a brand new facility which will provide an improved learning environment for generations of Kelso children.”
Paul McGirk, chief executive of the council’s development partner, Hub South East Scotland Ltd, added: “We are delighted with the progress being made on this project in partnership with the Council.
“Pupils and staff will benefit from modern, fit-for-purpose facilities and the community will benefit from investment in the local area. We look forward to making these plans a reality.”
Hub South East Scotland has appointed Morrison Construction as contractor to build the school.
