Admissions	Admissions
Admissions	Admissions Step 1 – Gather the documents. Collect the items listed in the admissions guidance: Academic Records for applicants in Grade 1–12; Proof of payment of the application fee of 30,000 JPY; a scan of the student's passport or birth certificate for birth-date verification; photos of the student and guardian(s); a guarantee letter from the employer if the company will pay school fees; and any individualized learning plan (ILP) or other supporting documents. This collection ensures the admissions team has complete material to begin with and supports a smooth review. The documents are used to determine eligibility and placement, and to facilitate the review of the application package. Step 2 – Submit your application. Submit the online application and complete all checklist items in your account. The online submissions are routed through the school's admissions portal, and submitting the form triggers the review process once all required documents are received. This step marks the transition from document gathering to formal review. Step 3 – Submission Review. After online submission, the child may be invited for an interview and a placement assessment. The placement assessment helps determine the appropriate class placement and whether English as an Additional Language (EAL) support or other specialized assistance is required. The outcome of the assessment informs next steps and potential supports. Step 4 – Application Decision. Following the assessment and review of prior school records, the school decides whether the child may register. Families are notified by email as soon as possible of the outcome, and the actual registration occurs at this stage if a place is offered. This decision ties together assessment results, records, and space availability. Step 5 – Enrollment Begins. The admissions office determines the first day of the school, and a family orientation may be organized if applicable. A WIDA test for English as an Additional Language (EAL) learners will be conducted as part of the enrollment process. Enrollment activities culminate in the start of the new school term.	Admissions 1. Submit Online Application. Begin by submitting an online application through the school's admissions portal. The application is accompanied by a non-refundable processing fee, which is valid for one academic year. The school places students into grades based on age, with an August 31 birthday cut-off guiding grade placement. Tokyo International School offers IB programs (PYP, MYP, DP) and considers multiple factors in admissions during the review stage. 2. Submit Supporting Documents. After starting the online application, follow the documents checklist provided in the system and upload the required materials. The checklist guides what needs to be submitted; requirements may vary by age/grade and specific circumstances. Completing all items in the system is essential before the admissions team proceeds. 3. Admissions Team Review. Fully completed applications are reviewed by the Leadership Team and relevant teachers. The review considers factors such as cultural and language diversity, learning diversity, and the resources available to support the student. The process also weighs space availability and class size when determining suitability. 4. Admissions Decision. The school states that English language proficiency is a factor for admissions, but not a requirement, and that admissions are pursued only when there is sufficient support to ensure success. A seat must be identified before assessments are conducted, which may be deemed necessary at the discretion of the admissions team. There is a non-refundable processing fee for each application, and the fee remains valid for one academic year.
