Boarding

- Boarding is not listed as part of the school's fee schedule; no boarding fees are published. The school operates as separate Early Learning / Elementary & Middle and High School day campuses.

Other costs and typical additional charges

- The fee schedule lists materials and trip/event fees above; other typical costs (for example: optional extracurriculars, uniforms, instrument hire, extra‑curricular trips beyond the standard trip/event fee, external examination fees, or lunch) are not broken out in the published summary fee page.

Summary of findings and missing details

- The published fee information provides: annual tuition by grade band, one‑time enrollment and building maintenance fees, materials fees, and trip/event fees, together with the statements that annual tuition includes 10% tax and that all fees are non‑refundable.
- The published information does not provide per‑term invoice amounts or a detailed public billing schedule (for example, exact term installments, due dates, or explicit payment methods). No boarding fees are published because boarding is not provided. For any required per‑term figures, installment amounts, exact due dates, or accepted payment channels, those specific items are not published in the fee summary and must be confirmed directly with the school's admissions/finance contacts.

Admissions

Admissions
1. Get to know KAIS. Book a school tour or contact the admissions office for more information. Tours help families understand KAIS programs and entry points, and admissions staff can answer questions about grade levels and how to proceed. The initial visit provides insight into whether KAIS aligns with your child's needs and learning style.

2. Create an Alma Account. Start your application by creating an Alma account, KAIS's student information system. This account is used to initiate and track the enrollment process and submit documents. A properly created Alma account is required before you can begin the formal enrollment application.

3. Start Enrollment Application. Once your Alma account is created, begin the application and provide the required documentation listed below. Required documents include the admissions application (through Alma), school transcripts/records from the past two years, two reference letters from the child's current or recent Math and English teachers, and detailed information on any special educational support needs. For Pre-K or Kindergarten (ages 3-6), you must also provide a Pre-Enrollment Medical Examination form and a medical check record by your doctor every six months until entry to Grade 1. Please ensure all learning needs are fully disclosed to avoid issues.

4. Document Screening. Your completed application will be reviewed by the Admissions Team. Our Admissions Director will track your progress and provide support along the way. This step ensures that KAIS understands the applicant's background and needs and helps coordinate next steps.

5. Trial Day. After reviewing all documents, we invite the student for a trial day. During the visit, the student will take placement tests in Mathematics and Language Arts to assess their level and needs. For overseas applicants, KAIS conducts an online interview instead of an in-person trial.

6. Acceptance Review and Enrollment Fees. After the trial day, KAIS educators review the child's performance to determine if KAIS is a good fit. If accepted, the family is notified by email and begins enrollment. The enrollment process includes paying the Enrollment Fee (one-time) and Building Maintenance Fee (one-time), along with Materials Fee and Trip & Event Fee as applicable to the grade. Tuition is charged on an annual basis.

7. Required Enrollment Documentation (summary). You will need to provide the admissions application (through Alma), school transcripts/records from the past two years, two reference letters from the child's current or recent Math and English teachers, and detailed information on any special educational needs. For Pre-K or Kindergarten (ages 3-6), you must also provide a Pre-Enrollment Medical Examination form and a medical check record from your doctor every six months until entry to Grade 1. Open communication about learning needs is essential to a positive enrollment experience.
