School Crest
The crest or coat-of-arms of Archbishop Rummel High School symbolizes the school in a fourfold manner. In the upper left quadrant is the star of faith of the Christian Brothers. This star symbolizes the faith of the faculty in youth and the faith which they seek to foster in their students. Archbishop Joseph Francis Rummel is symbolized in the upper right quadrant by a hunting horn from his own coat-of-arms. Dominating the lower left quadrant is an open book, symbolic of the knowledge provided by Archbishop Rummel High School and which is the basis of all the education and culture that is available to the students.

The seal of the state of Louisiana completes the crest in the lower right quadrant. The pelican is the state bird of Louisiana. This bird which gives its blood to sustain its young symbolizes the devotedness, which should characterize the Archbishop Rummel student. Separating and joining the quadrant is the cross, symbolizing religion, which keeps each endeavor of the school in its proper perspective and joins them all under its benevolent influence.

Each Archbishop Rummel student proudly wears the school crest everyday on his school uniform.
