The following is a list of publishing companies and their materials that GCCA purchases materials to use in its academic program, grades 1st through 5th Grade. It should be noted, however, that teachers at GCCA are instructed to teach “beyond the textbook” as they teach children from a Christian perspective. Subjects are taught as parts of an integrated whole with the Scriptures at the center. For more information, please see our Educational Philosophy (Handbook, p. 6).
