YISS is part of the Network of International Christian Schools (NICS) and offers an American curriculum with a Christian foundation. What makes YISS distinctive is its dual-track system: the NICS program includes Bible classes and chapel services, while the Oasis program is designed for non-Christian families and replaces religious instruction with philosophy and character education. With students from 50+ nationalities, YISS is one of the more diverse international schools in Seoul.

Academics
YISS follows an American curriculum structure with differentiation through its two program tracks. The NICS track integrates Christian worldview education, including Bible classes and chapel, throughout the academic program. The Oasis track offers the same core academics but replaces religious components with philosophy, ethics, and character education courses. The school offers a selection of AP courses, though the range is narrower than larger schools like SIS or KIS. Class sizes are small, often 15-20 students, allowing for personalized instruction. The school focuses on developing well-rounded students, balancing academics with service learning and character development.
Admissions
Admissions at YISS are generally less competitive than at schools like SIS or SFS, though popular grades can fill up. The application process includes academic records, teacher recommendations, and a family interview. Families choose between the NICS and Oasis programs during enrollment. Annual tuition ranges from approximately 36M KRW for lower grades to 42M KRW for upper school, making YISS one of the more affordable foreign schools in Seoul. The school serves a significant population of missionary families, and some tuition assistance may be available for families in full-time mission work.
Campus and Facilities
The YISS campus in Yongsan is functional but more modest than some of the larger, newer international schools in the area. Facilities include standard classrooms, science labs, a library, a gymnasium, art rooms, and outdoor play spaces. The campus is urban and compact, reflecting its central Seoul location. Families expecting large sports complexes or state-of-the-art performing arts centers may find the facilities limited. However, the Yongsan location provides easy access to public transportation and the amenities of the surrounding neighborhood, including parks and cultural venues.
Community and Culture
The YISS community is warm and close-knit, with a strong emphasis on mutual support and service. A significant portion of the parent body comes from missionary and diplomatic backgrounds, which gives the school a distinctive culture centered on faith, service, and international understanding. The Oasis program has broadened the community to include non-Christian families, adding more diversity to the school culture. Parent involvement is high, and the school organizes regular community events, service projects, and cultural celebrations. The smaller school size means families tend to know each other well, which can be a positive for newcomers looking for a welcoming environment.
