The Atonement Academy is a parochial, Catholic school in the Personal Ordinariate of the Chair of Saint Peter in San Antonio, Texas.

The minimum requirements for high school graduation are established by the Texas Catholic Conference Education Department.

The Atonement Academy offers a wide variety of classes including grammar and literature, science, Texas, U.S., and World history, U.S. government, and economics.

The music program is centered on choral instruction, where the various student choirs play a part in the liturgy of the Mass.

Other, non-academic activities that are supported include Scouting (both boys and girls), chess club, National Honor Society and Student Council.

Every other year until 2020, the students of the academy had an opportunity to go on a parish-wide pilgrimage to Rome, and attend Mass in some of the greatest churches in Christendom.

The high school uniforms in particular are noteworthy for their elegance, maturity, and strict modesty, and in the junior and senior years include the class ring.
