Let the school know you're thinking of applying — they can share their prerequisites and help you through the process.
It's best to ask — circumstances can change at any time.
Admissions Process
Step 1 — Inquiry and tour: Submit an inquiry to receive more information and to book a school tour. The Admissions Office will contact you to discuss your child, your family's background, and to coordinate a visit to the campus. English language ability is essential for at least one parent to communicate with the school and to understand written communications. The school uses English as the language of communication, instruction and inclusion.
Step 2 — Application completion: Complete the application as the formal first step in joining Seisen. After the application is submitted, the admissions process moves toward the review and selection stages defined by the school. All applications are considered on a case-by-case basis, with the child's ability to benefit from Seisen's academic programme as the prime criterion. The Head of School reserves the right to accept or reject an application based on space and alignment with the school's mission.
Step 3 — Review: The relevant principal will review the application and the admissions office will contact you with the outcome. This review considers how well the applicant fits the classroom environment, language support needs, and the school's capacity to meet the student's educational requirements. You may be requested to provide additional information or documentation to support the review.
Step 4 — Assessments and interviews: The admissions office will schedule the family interview with the kindergarten principal for applicants advancing to the next stage. For elementary, middle school and high school applicants, the admissions office will schedule assessment tests in mathematics and English. Interviews and tests are used to gauge fit with the curriculum and to verify information provided in the application.
Step 5 — Decision and further interviews: Based on the assessment results, the admissions office will book the family interview with the relevant principal. This step adds a formal discussion about the student's goals, language needs, and support requirements, if any. Final placement decisions are made after reviewing the assessment outcomes and interview notes.
Step 6 — Offer and enrollment package: Applicants eligible for a place will receive an enrollment package. Families should communicate their intent to accept or decline the offer within the package timelines. Space availability and the family's ability to support the School Mission are considered before a place is offered.
Step 7 — Enrollment completion: Enrollment is official upon receipt of the signed letter of endorsement, registration fee payment, parent/guardian commitment agreement, and, if applicable, the summer school agreement. The school will also provide next steps for onboarding and orientation.
Step 8 — Welcome and health information: After enrollment, a welcome email will be sent from the Magnus Health platform requesting student health records and any additional information for new students and parents. You will be guided on submitting health records and other onboarding requirements.
Waitlist/Pool
Seisen operates based on space availability. Priority acceptance is given to certain categories (siblings of current students, children of alumni, children of faculty and staff, returning students, and children from Catholic families), but acceptance is not automatic for these groups; the school still assesses fit with the curriculum and the family's support of the Mission. For returning students, acceptance depends on space, and an applicant may need to be placed on a waitlist until space opens up. If space is limited, a waitlist can be used while the school reviews capacity and considers new or returning applicants.
Scholarships
Seisen offers a Corporate Contribution Plan, a corporate scholarship program for foreign-based corporations responsible for expatriate employees' educational expenses. The program is described as a means for eligible corporate sponsors to contribute toward a student's education, and interested families should contact the Seisen Business Office for further information. There is no information indicating individual need-based or merit-based scholarships beyond this corporate program.
