Association of Christian Schools International (ACSI)

The Association of Christian Schools International (ACSI) strives to enable and equip Christian educators and schools worldwide to effectively educate children and young people with the mind of Christ. Thus, students will be prepared for life because Christ, the creator and sustainer of the universe, possesses “all the treasures of wisdom and knowledge.” (Colossians 2:3) The life and mind of Christ is nurtured in the lives of students through redemptive relationships with faculty who recognize that reconciling the heart and mind to God is the foundation of their work.

To this end ACSI seeks to equip schools for greater effectiveness, year after year. The many programs and services we offer are intended to enrich the teaching of Truth—God’s Word revealed through Scripture as well as through creation. We seek to increase the vision for students’ intellectual development through Christian faculty who model a rigorous Christian mind in their teaching and leading. We believe that schools can increasingly achieve their vibrant mission as their operational practices grow in excellence.

The people of ACSI, in our Colorado Springs headquarters and the seventeen regional offices around the world, are eager to assist educators and schools in guiding their students to reach their full potential in Christ. We desire to provide the tools necessary to rekindle vision, energize practices, and equip educators to achieve this goal.

Association of Classical & Christian Schools (ACCS)

The primary mission of this association is to promote, establish, and equip schools committed to a classical approach to education in the light of a Christian worldview grounded in the Old and New Testament Scriptures. The mission of the association is both to promote the classical approach, and provide accountability for member schools to ensure that our cultural heritage is not lost again. This mission will be accomplished through the work of the Association of Classical and Christian Schools. Through these various means, ACCS seeks to set an educational standard for a unified and directed approach to classical and Christian learning.

Our mission is also to equip schools in teaching such subjects through the methodology known as the Trivium (grammar, logic, and rhetoric), the educational foundation of our Western culture. We believe that God will bless this approach as He has in the past, as long as it follows the principles set forth in his Word.

We recognize that Christ was born in the reign of Caesar Augustus, and that Christianity took root and grew to maturity in the West. For this reason, we believe that we must teach certain subjects so that they are understood and appreciated. This includes ancient history, languages, and culture, studied in the light of biblical Christianity and its impact on western culture. We recognize our cultural heritage as a gift from God, but in seeking to restore that heritage we by no means are intending to idolize it. Therefore, we ground all that we seek to do upon the revelation of God, both in creation and in Scripture, with the former being interpreted by the latter. The triune God of Scripture has created an ordered universe, which can only be fully known through an orderly submission to His revelation of Himself in Scripture. As Christian schools, we are seeking to equip member schools to integrate all their teaching around the revealed Word of God.

In line with this vision for education, we commend to our member schools the following works which will help restore a classical and Christian framework for our schools.
