School song
We are proud that our school is St.Margaret's, Seria
The place of our studies to fit us for life.
Each morning we study with teachers to guide us.
At home we are busy to learn all they've taught.
We are boys and we are girls with lives stretched out before us.
Oh! what shall we do with this life that is ours?
We'll fit ourselves daily to be useful people;
To serve God and neighbour the rest of our lives.
School prayer
Almighty God, bless our schools.Help all teachers and scholars.
Give us grace to do what is right
and strength to do what is difficult.
May we always honour Your name. Amen.
