Member Milestones
Recognizing accreditation milestones of 25, 50, 75, 100, and 125 years
Celebrating excellence in accreditation
Throughout its more than 125 years of service, Cognia Accreditation has engaged schools across the globe that meet rigorous standards focused on productive learning environments, equitable resource allocation, and effective leadership.
Earning accreditation from the Cognia Global Accreditation Commission recognizes that the school:
- Has successfully completed our third-party external review
- Meets Cognia Performance Standards
- Embraces continuous improvement
Schools in good standing can maintain their accreditation for a six-year term.

Congratulations to all 481 institutions that have reached a significant accreditation milestone during the 2024–2025 school year.
