Inspired by a deeply rooted tradition of English schools, but adapted to the local Maryland clime, the System of Houses at The Avalon School is designed to help foster among its students the same chivalrous and noble spirit that was brought here by Lord Baltimore's first Gentlemen Adventurers. Each boy is able to ennoble both his own House and his School by channeling his natural sense of competition toward the service and enrichment of something larger than himself, (whether in school-wide contests and festivals, or simply in his daily academic work).
The Houses themselves are named in honor of men or families whose indelible mark helped form the character of Maryland: Stewart, Calvert, Carroll, Washington. Every boy, as well as every member of the faculty and staff, is placed in one of these four Houses. Brothers, and eventually sons, will automatically be placed in the same House.
The coat of arms borne by each House shares both its essential form and one symbolic color with The Avalon School Crest: GOLD for nobility or BLACK for humble constancy. However each House also bears in its coat of arms another color and symbols which represent the character or contributions of the family for whom it is named.
