The International Education Quality Assurance System (IEQAS) is an evaluation program managed by the Ministry of Education. It comprehensively assesses universities on their recruitment and management of international students, their educational environment, and their overall internationalization capabilities to certify outstanding institutions.

This certification evaluates various criteria, including support systems for international students' academic and daily life, visa management, and efforts to prevent illegal stays. It serves as a vital indicator of the quality of international education and the university's institutional credibility.

Osan University continues to enhance the quality of its international education by implementing a systematic student management system and operating diverse global programs.
