The lower part of the field consists of two panels, blue and gold, which represent heaven and earth. The colours also symbolize both spiritual and material accomplishment. The letters "ACS" in red symbolize life forming a bridge between both; they also symbolize the blood of Christ uniting heaven and earth. In addition to the school name, the letters ACS are also variously said to spell out Academic achievements, Christian Character, and Sportsmanship or Service beyond self. Finally, the overall shape of the shield represents the knightly virtues of chivalry, honour, loyalty, valour and manliness.
