Admissions	Admissions
Admissions	Admissions 1. Admissions Process GSIS presents a clearly staged admissions path. Official application opening for the 2026–2027 school year is January 12, 2026 at 9:00 a.m., and seat availability by grade will be announced earlier (December 8, 2025). After you submit the application, you will be notified whether a seat is available for the grade you requested or if you have been placed on the waiting list. This first communication sets the tone for the next steps and clarifies whether your child has an immediate seat or remains in consideration for the upcoming year. Step 2) Prepare Required Documents Gather and prepare the forms and documents GSIS requires, including language survey forms, reference forms, and a medical form, so the admissions team can assess your application fully. You should download the necessary forms, fill them out, and ensure all information is accurate and complete before submission. Having these documents ready helps avoid delays and keeps your timeline on track. Step 3) Apply Online Complete the online application using scanned copies of the filled forms. Upload the required documents as part of the application package and ensure the submission confirms successfully. This step initiates the formal review and determines whether supplemental documents will be requested. Step 4) Submit Application Fee Pay the application processing fee as part of the application, and submit the bank receipt along with your application. The fee is non-refundable and must be paid to the designated GSIS bank account. Including the receipt with the online submission helps the Admissions team verify your file quickly. Step 5) Admissions Review and Documentation Requests Once the application and supporting documents are received, GSIS will review them and may request supplemental documents if needed. The review considers grade level suitability, readiness for the IB program, and alignment with GSIS's admission criteria. Prompt responses to any additional requests help avoid delays in the decision process. Step 6) Admissions Test and Interview The admissions office will arrange an entrance test and/or interview. If you would like the test conducted from overseas, the admissions officer can send the test paper via FedEx. The test and interview assess academic readiness and language proficiency as part of the overall evaluation. Step 7) English Proficiency and Special Criteria The school may review test results and request additional English-language assessments (ELL or other English acquisition tests) as needed to determine placement. This step helps GSIS determine whether supports are required for language development. Clear communication about any language support needs is important at this stage. Step 8) Admission Decision and Offer/Waitlist Communication The principals and teachers will make a final admission decision, and acceptance or rejection letters will be sent by the Admissions office. If a seat is not available, you will be placed on the waiting list and notified of any changes in status. You will receive guidance on next steps if a seat becomes available. Step 9) Enrollment and Orientation If admitted, you will receive an invoice with the tuition and related fees. Payment of the invoiced amount within the specified period is required to secure the seat. The student then participates in New Student Orientation as part of joining GSIS. 2. Waitlist/Pool GSIS communicates seat availability after an application is reviewed and may place applicants on a waiting list when no immediate seat is available. You are notified if you are placed on the waiting list and provided with any subsequent steps or timelines. For the 2025–2026 cycle, some grade levels may have no available seats for the second semester, with seat availability for 2026–2027 determined by current students' reenrollment status. Overall, seat allocation is grade-specific and contingent on current enrollment and reenrollment. 3. Scholarships GSIS does not publish a formal merit-based scholarship program on its admissions pages. Instead, the school lists several financial arrangements that affect tuition costs: - There is a 2% discount for lump-sum tuition payments, offered under certain conditions and deadlines for the current year cycle. Returning students' first-semester and second-semester payments have targeted due dates to secure seats and class schedules. - Families with two or more GSIS students receive a 20% tuition discount starting with the second child; the policy notes that the discount amount can be transferred to an older sibling who is not receiving the discount, and that this applies from the 2026–2027 school year. Returning students are exempt from paying the entrance fee, and the same tuition schedule applies to both new and returning students, with other fees remaining the same. If you're seeking traditional need-based or merit-based scholarships, GSIS does not list these on its official tuition resources; instead, the school highlights tuition-related discounts and payment options described above. The school's tuition and fees page also outlines specific fees and their refundable status, which are important for budgeting and planning.

If you need a plain-language summary tailored to a specific grade and currency (KRW or USD), I can provide a concise quote sheet.	Admissions Step 1 — Inquire. Start by contacting the Admissions team to learn more about YISS and the programs offered. Campus visits and admissions events are available, with daily tours and Admissions Open House events scheduled periodically. An Open House example is the Admissions Open House for families with children entering Kindergarten and 1st Grade in August 2026, which provides a chance to see the campus and ask questions. Step 2 — Check Eligibility and Gather Required Documents. To be eligible, an applicant must live with a parent or legal guardian; YISS does not host exchange students, offer boarding services, or sponsor student visas. Valid eligibility documents must be updated every year during re-enrollment. Review the eligibility requirements and collect the documents specified for your child's grade level before applying. Step 3 — Online Application. When you are ready, complete the online application. The school provides an online portal to submit the application after confirming eligibility and gathering documents. Step 4 — Admissions Testing and Timeline. After submitting documents, the Admissions team will contact you if any documents are missing. Selected applicants applying for kindergarten or 1st grade may undergo an initial screening, and 2nd–12th graders may be asked to provide recent standardized test results (MAP, ISEE, TerraNova, etc.) or English proficiency assessments if needed. Decisions can be an offer or placement in a wait pool, and the wait pool is not chronological and lasts only for the applying year. Step 5 — Offer, Acceptance, and Enrollment. If an offer is made, you will receive an offer letter via OpenApply and must respond within two business days; tuition arrangements must be made within five business days. The non-refundable Application Processing Fee of ₩500,000 is charged upon acceptance, and applicants required to sit for interviews or tests may be charged this fee even if not accepted. There is a capital development fee as part of the fees, and a comprehensive list of tuition and fees is published for review.
Scholarships	Scholarships GSIS does not publish formal merit-based scholarships on its official pages. The school does offer a 2% early payment discount and a 20% tuition discount for the second child of a family with two GSIS students (applicable from the 2026–2027 school year, and potentially transferable to an older sibling under policy). Returning students are exempt from the entrance fee, and tuition remains subject to the standard fee schedule. These policies are described in the Tuition and Fees section.	Scholarships Scholarships: YISS does not offer scholarships at this time. This applies across the student body and is stated in the admissions FAQ.
Waitlist	Waitlist - The school notes that after submitting the application, applicants are informed whether a seat is available or whether they have been placed on the waiting list. Seat availability is grade-specific and depends on current enrollment and reenrollment status. For some grades in the 2025–2026 cycle, there are no available seats for the second semester, and seat availability for 2026–2027 is determined by reenrollment. This indicates a formal waitlist/pool process rather than ad-hoc seat offers.	Waitlist Wait Pool (not a formal waitlist): When space is not available, qualified applicants are placed in a wait pool and will be considered if spaces become available. The wait pool is not in a fixed order and applies to the applying year only; applicants should update or upload new documents to keep their file current. If a student remains in the wait pool and a mid-year vacancy opens, decisions can be made quickly based on complete and current files. For subsequent years, applicants must reapply.
