The CISP curriculum is biblically based, academically excellent, and practically oriented.
CISP's Curriculum Guide contains details on our educational philosophy, our approach to learning, and descriptions of the courses offered at each grade level.
Every class is taught from a biblical perspective.  We believe the Bible not only communicates “religious” knowledge, but that it provides a lens that illuminates all aspects of life. Therefore, we endeavor to integrate all of our educational disciplines with a distinctively biblical world and life view. Not that we attempt to substitute the Bible for a science textbook; rather, the Bible gives us a perspective through which to view science as deeply meaningful and ordered to the glory of God. We want each of our students to be familiar with this biblical perspective on reality, and be able to understand everything from that Christ-centered perspective.  
We recognize that all truth comes from God.  This means we seek the best resources from both Christian and non-Christian authors and publishers and encourage students to read books from both.  In fact, we see it as a crucial part of teaching the students how to think about and relate to the world around them.  They need to be exposed to the various philosophies and beliefs present in the unbelieving world, and taught how to respond from a Christian perspective, sifting truth from error.  Then they may live in that world with confidence, having been firmly grounded in the truth.
