The Christian school is not a school merely for the sake of academics, but for the sake of fulfilling the church's God-ordained role in carrying out the Christian education mandate (Deuteronomy 6:7, Proverbs 22:6, Timothy 3:15-17). This curriculum was written on the premise that all truth comes from God and that any teaching of man that is contrary to the clear teaching of the Word of God must be rejected and refuted. The curriculum and its correlated materials teach, for example, that arithmetic, grammar, and spelling are all rule governed activities. If they are not taught that way, but, on the contrary, they are taught on the idea that the individual may "do his own thing; in these matters"; then the purpose of arithmetic, grammar, and spelling in social existence is destroyed. This common sense approach fully accords with Scriptural principles about orderliness and authority. The teaching material for these subjects is also bound with specific examples aimed at Christian character building. The final aim of Christian education is the projection of individuals who will habitually choose to do because it is right to do right. Christians have a standard of right and wrong and we must train students to habitually choose to act upon the teachings of that standard, which is the Word of God.

Bible time is the most important half-hour of the school day. It is the very first subject taught each day and by its very nature, the most interesting and important subject. Our Bible class is an inter-denominational program which presents stories of the Old and New Testaments. This unique Bible program respects all Christian denominations. It encourages students to be active in their churches, with the ultimate goal of each student accepting Jesus Christ as Lord and Savior. Bible teaching reinforces all the teaching about character and Christian living throughout the day. The Bible is the most effective character forming tool available. It will provide the receptive bearer with a firm foundation for life and a shield against error.

The Raintree Christian Academy uses the Abeka curriculum.

Abeka offers a decidedly Christian approach to education. The company's  mission, as stated on their website, is "to lead young people to Christ and  train them in the Bible, Christian character, language, and traditional subject  matter ... so they will have a firm foundation from which to evaluate the  present and make proper decisions for the future."

Abeka uses a traditional approach to education with a strong emphasis on  biblical principles.  The Abeka curriculum relies heavily on textbooks and workbooks which are created by and for Abeka.
