Cardinal Montessori School (Top-Ranked �� School for 2026)

Cardinal Montessori School (CMS) is the oldest AMS affiliated Montessori school in Prince William County with roots back to 1959. Our school is committed to assist each child to reach his/her full potential in the areas of child development.

Our philosophy begins with a belief that a child comes to us with unlimited potential and must be treated with respect and dignity as the adult they are to become.

The most important qualities a child develops in our classes are self-confidence, self-esteem, independence, self-discipline, thinking skills, and a love of learning.

Each child is taught that they are capable of making decisions that influence them and that they are responsible for the decisions made.
