School Shield
The school shield was formerly adapted by the Maryknoll Sisters from the Dominican one, with 8 alternating black and white triangles divided in the middle by a cross marked red and blue. On top of the shield is a dove, representing the Holy Spirit. The motto of the school was written in Latin underneath, "Dominus Illuminatio Mea".

 

In 1983, when the school name was changed to Marymount Secondary School, theshield was re-adapted. The middle section was changed from the Dominican one to MSS, the initials for Marymount Secondary School and Maryknoll Sisters School, embracing the past and the present. The dove, representing the Holy Spirit still hovers above the school name, and the motto was translated into English "The Lord is my Light". MSS badge
