Our students learn within a self-paced system, working independently of each other within multi-grade learning centers.
Our educational philosophy is structured around building relationships with our students and discipling them into their relationship with Jesus Christ.

Cornerstone is more than a school, it becomes a family. The teachers are highly invested in each student and peer relationships form that last a lifetime. I attended Cornerstone from kindergarten through 12th grade and received an outstanding education. I was well equipped for the independent study required in college. As an educator myself, I highly recommend Cornerstone!

I am so grateful for my time at Cornerstone School. The Christ-centered environment cultivated a sense of community and values that shaped my character. The opportunity to accelerate and graduate early was a testament to the school's commitment to individualized learning. I entered college feeling well-prepared, thanks to the strong educational foundation. I have fond memories of my time at Cornerstone and highly recommend it for those seeking this environment for their family!

Enrolling our children at Cornerstone School was the best decision we have ever made. The teachers genuinely love and care for the students well being. They work so hard to ensure each student succeeds. The school is more like a community as everyone is willing to help wherever it's needed. The education level is high and really fosters success. Mr B really helps students think outside the box and this encourages kids to be able to think for themselves. I promise you will not regret having your children attend Cornerstone School.
