Highly recommend Cornerstone Christian School to any family in search of a discipleship type of school for their children. Both of my students have attended CCS since kindergarten. It is a great learning environment and also character building.

I left the school to move across the country in after my 9th-grade year, but my years from 3rd-9th grades were wonderful, formative to my Christianity, and left an impact that no one can take away. I highly recommend sending your children there, they will have an amazing experience.

We are considering putting our child in this school. A friend of ours has a child in school and highly recommends it, saying all the teachers are very loving, and they instill Christian beliefs such as creation during their teaching. They memorize verses weekly and some of the kids recite these in chapel. Bible is one of the subjects kids learn. Also says they are very good academically and get top scores in testing. It is cheaper than some of the Christian schools in the area, though not as cheap as Temple Baptist.
