The fundamental reason for the existence of Saint Ambrose School is Jesus Christ, Our Lord. Our school shares with the Church community and with society the responsibility of forming all in the likeness of Christ. Through our educational mission, we proclaim, witness, and spread the Word of God. We accomplish our educational mission while providing our students with the opportunity to grow in the faith to which they were initiated in Baptism. Through knowledge of God, our students may come to an understanding of their relationship to the whole People of God and to their individual parish communities. Through an examination of the meaning and implications of Christian commitment and example, our students may come to understand their responsibility to the Church and to society.
 
While the study of religion is central to the curriculum, we are also committed to providing quality education in other academic areas from pre-kindergarten to eighth grade. We are further committed to creating a learning environment that endeavors to meet the individual needs of our students while challenging them to achieve their highest potential. We recognize the essential role of parents and guardians in the religious, academic, and social formation of the students. We welcome the involvement of parents and guardians, parish and local communities, and agencies of the Archdiocese of Washington.
 
Our values are mirrored in the goals of our programs and in their implementation. We continually endeavor to re-evaluate and renew our commitment to our values and to sustain quality education. We accept the challenge to reflect the mandate given to us by the Church to teach and live the Word of God.
 
Our Catholic School welcomes students and families of all faiths. 

Our mission is to create life-long learners who value and embrace their faith. We approach all of our school endeavors in the spirit of the core Catholic values of loving God and our neighbors within this supportive community. St. Ambrose Catholic School students are encouraged to take educational and personal risks, set and accomplish goals based on their academic abilities, and understand that they can accomplish anything through Christ.
