The school crest was probably designed by a Christian Brother who unfortunately remains anonymous. In the ninety six year history of the school, many variations of the school crest have appeared. However, the following is an interpretation of the present official school crest.

The cross, burning with faith, is placed appropriately at the centre because it signifies that God is central to St. Edmund?s - being a Christian Brothers School. The School logo is surmounted by a star. As the star shines in the darkness it is regarded as the symbol of enlightenment and instruction. Embracing the logo is the scroll of learning which is done in the Celtic tradition - so deftly intertwined that the complete design gives a sense of satisfaction which harmony, unity and good team work produce.

The saplings correspond to every boy who walks into the school to prepare for life. The blossoming of the two flowers from the saplings represents the full flowering of the personality of this boy. The two flowers on either side signify the integration of the values in life - freedom and responsibility, compassion and justice, the ying and the yang. It also signifies the healthy balance between the curricular and the co-curricular which is promoted in the school. The crown at the foundation of the saplings symbolizes the sense of fulfilment and accomplishment experienced when the young man develops a balanced and integrated personality which will ensure him of abundance throughout his life.
