For the majority of pupils, this will be the first time they have stepped foot inside their new school building.
The Council’s Policy Lead for Education, Councillor Yvonne McNeilly said: “We want the very best for our young people and we want them to succeed in life.
“This wonderful new state-of-the-art high school in Oban will help us to achieve that and will provide our young people with a learning experience where they can succeed.
“This really is a school fit for the 21st Century and I wish all the staff and pupils every success and happiness in their new school.”
The new school has been built by Argyll and Bute Council in partnership with hub North Scotland Ltd.
It has capacity for up to 1,300 pupils and is located next to the current school site.
Morrison Construction, Managing Director of Building Highlands, Donald Mclachlan, said: “It is wonderful to see this fantastic new education facility completed with teachers and pupils moving in after the Easter holidays.
‘‘Oban High School marks the third school completion of four education facilities we will deliver for Argyll and Bute Council and hub North Scotland.

hub North Scotland Chief Executive, Michael Padzinski commented: “We are delighted to have successfully completed this exciting new school in partnership with Argyll and Bute Council.
"The school is an integral part of the local community and provides a modern teaching and learning environment for pupils and staff on their learning journey.
