K-12 Accredited

Since 1981 Cornerstone has partnered with families in the provision of a Christian education centered on a biblical worldview. 

Cornerstone maintains K-12 accreditation by two organizations, with the leading agency being the Association of Christian Schools International (ACSI). ACSI is an internationally recognized accrediting organization. It ensures member schools have undergone careful self-analysis and have met accrediting standards for their educational program. The Connecticut State Department of Education recognizes ACSI as an approved accrediting agency. Cornerstone teachers actively maintain ACSI teacher certification.

Our partnership with ACSI provides us with the ability to join other, like-minded Christian schools for various events competitions. Additionally, our faculty is able to network with other Christian educators across the country through various professional development opportunities. 

Cornerstone is also dually accredited by the Middle States Association: Commissions on Elementary and Secondary Schools (MSA).
