Member Milestones
Recognizing accreditation milestones of 25, 50, 75, 100, and 125 years
Celebrating excellence in accreditation
Throughout its 130 years of service, Cognia Accreditation has engaged schools across the globe that meet rigorous standards focused on productive learning environments, effective resource allocation, and impactful 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
Reaching a milestone in your accreditation journey demonstrates a strong commitment to educational excellence and improvement. As part of our milestone program, we recognize institutions that reach 25, 50, 75, 100, or 125 years of accreditation.
Institutions celebrating in 2025–2026
Congratulations to all 646 institutions that have reached a significant accreditation milestone during the 2025–2026 school year.
