What is the cost of tuition?

We realize that choosing private education for your children is a lifestyle commitment. We re-evaluate our tuition rates each year considering the impact they have on our community of families. We have committed 10% of our annual budget to fund scholarships. If you are in financial need, you can submit a scholarship application.

What is Classical Education?

Classical education is a philosophy of teaching that utilizes a child’s natural learning abilities. In the grammar school, children love repetition, singing, chanting and movement so these are used in all areas of learning. Once they move into middle school, they challenge their earlier thinking by asking questions, getting to the root of knowledge and understanding the world they live in. Finally, a student has been given knowledge, reconstructed that knowledge in their own understanding and now in the final phase of education they learn to present their knowledge and opinions eloquently and persuasively. In all levels, content is integrated to make every aspect of learning connected and meaningful. Check out the Classical Difference to have an in-depth look at the benefits of a classical Christian education.

Our family joined Cornerstone Academy three months into the school year and feel so blessed that God led us here. We were met by a loving and encouraging group of parents, staff, and teachers. Our daughter transitioned quickly and loves her teachers and new friends – and is anxious to get back to school in the fall. We are so thankful to be part of the Cornerstone Academy family! Brett 

My son started at Cornerstone when he was in preschool. Now as a 5th grader, we can see how much Cornerstone set him up for long term success. My heartfelt thanks.


These last 2 years at Cornerstone have been wonderful for Grayson academically, socially and spiritually. I’ve seen him shift from just doing his school work to developing a “love for learning”.
