Sinclair Academy in Winchburgh opened its doors on Tuesday, 15 August, to 80 First Year pupils.
It is the third and final school built as part of the Winchburgh Schools Campus project, the council's largest ever investment in education at more than £60 million. Winchburgh Academy, Holy Family Primary and shared sports block have already opened on the site.
Pupils and their parents/carers were greeted by a piper when they arrived at school for the first time, with a breakfast reception organised to mark the big occasion.
This was followed up by a special assembly, where every pupil was given a special welcome bag, followed a class where their key adult was allowed to attend with them.
The morning was rounded off with the short trip to neighbouring Holy Family Primary School for a joint Mass.
Sinclair Academy Headteacher Dr Gerry Burns said: "We had a fantastic first day at Sinclair Academy and thanks to all the pupils, parents/carers and staff who shared it with us.
"It's a huge privilege to be part of a new school opening, as we start to build a brand-new school community of learning and faith.
"The new school is fantastic venue for learning, and I look forward to an exciting year ahead."
