Archbishop of Perth Roger Herft and Education Minister Peter Collier were among those at the opening of the Graceful Boulevard school.
Refreshments were served following the Friday, May 8 ceremony that began at 11am.
The Chapel of St James is now being constructed on the grounds and is expected to be completed later this year.
It can be seen from Marmion Avenue.
This space will become the home of the Alkimos/Yanchep Parish, as well as serving the students at St James� Anglican School for their weekly worship.
