Cornerstone is in the midst of its 33rd year of partnership with families in the provision of a Christian education centered on a biblical worldview.
Cornerstone has been a member of the Association of Christian Schools International (ACSI) since 1981; the K-8 program has maintained accreditation since 1988. Cornerstone received its K-12 ACSI Accreditation in Spring 2012. 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.
All Cornerstone teachers actively maintain ACSI teacher certification in order to teach in each of their positions.
