The Illinois Association of Christian Schools is the state chapter of the American Association of Christian Schools (AACS), one of the leading organizations of Christian schools in the country. The IACS was founded in 1974 and over the years has grown to represent approximately 25 conservative Christian schools statewide.

As a state affiliate of the AACS our benefit program expands to a national scope affording a broad spectrum of both cost saving options (such as a national health insurance program) and professional helps. The IACS meets on a regular basis during the school year for information distribution, discussion of current Illinois educational issues or trends, and fellowship. Our state organization also sponsors a yearly teachers’ convention bringing in workshop speakers of national recognition. This convention gives our faculty and staff opportunities for professional development and spiritual growth.

The Illinois Association of Christian Schools places a priority on doctrinal agreement among the member schools. Member schools may not be a part of the ecumenical movement or promote the doctrine or practice of the modern charismatic movement or the exercise of the “sign gifts” (speaking in tongues, gifts of healing, sign gifts, etc.).

Other Information

All schools requesting to join are required to submit a doctrinal statement and a copy of your parent/student handbook.


We believe that the Bible, both the Old and New Testaments, was verbally inspired of God and is inerrant and is our only rule in matters of faith and practice. We believe in creation, not evolution; that man and woman were created by the direct
act of God and in the image of God; we believe that life begins at conception where the only genders (male and female) are divinely predetermined. We believe that Adam and Eve, in yielding to the temptation of Satan, became fallen creatures. We believe that all men are born in sin. We believe in the Incarnation, the Virgin Birth, the Deity of our Lord and Savior, Jesus Christ. We believe in the vicarious and substitutional Atonement for the sins of mankind by the shedding of His blood on the cross. We believe in the resurrection of His body from the tomb, His ascension to Heaven, and that He is now our Advocate. We believe that He is personally coming again. We believe in His power to save men from sin. We believe in the necessity of the New Birth, and that this New Birth is through the regeneration of the Holy Spirit. We believe that salvation is by grace through faith, plus nothing minus nothing, in the atoning blood of our Lord and Savior, Jesus Christ. We believe that God ordained marriage and family as the foundational institution of society. We further believe that the only Biblically sanctioned marriage is the public, monogamous union of one man and one woman that is intended for a lifetime and that any sexual activity outside of marriage is sinful and is detrimental to society. We believe in the Biblical doctrine of ecclesiastical separation, and therefore believe that churches and Christian schools shall not be members of or in agreement either with organizations or movements (such as the World Council of Churches and the National Council of Churches) which deny the fundamental doctrines found in this statement or with ecumenism which minimizes doctrinal distinctives. We further believe in the completed revelation of Scripture which allows neither for direct revelation from God today, nor for continuation of temporary New Testament sign gifts, such as visions, dreams, prophecies, healings or speaking in tongues, such as is practiced in the Charismatic movement.
We believe that this doctrinal statement (statement of faith) is basic for Christian fellowship and that all born-again men and women who sincerely accept it and are separated from the world of apostasy and sin can and should live together in peace, and that it is their Christian duty to promote harmony among the Believers.


Membership will not be afforded to those associated with, members of, or in accord with the World Council of Churches, the National Council of Churches, the modern charismatic movement, or the ecumenical movement.
