Admissions

Admissions
1. Families begin by contacting the school to request information or by submitting an application form. At this stage, parents are typically asked to provide documents such as copies of the child’s birth certificate, passport, and recent school records. The school also requests photographs and medical history to complete the application file.

2. Students may be invited for an entrance assessment or interview to determine placement, especially for those entering higher grades or requiring English support. Younger children may be observed in a classroom setting to assess readiness. This step helps the school ensure that students are placed in an age-appropriate and academically suitable program.

3. If the student meets the entry requirements, the school issues an offer letter confirming placement. Parents are asked to review the offer and accept within a given timeframe. Acceptance at this stage also depends on space availability within the grade.

4. Once the offer is accepted, families must pay the one-time registration fee, refundable deposit, and the first semester’s tuition. Proof of payment is required to finalize enrollment. Failure to pay within the deadline may result in the place being released to another applicant.

5. After fees are settled, the child is officially enrolled. Parents receive details about uniform purchase, transportation options, and orientation schedules. The school provides information on first-day procedures and introduces families to key points of contact, such as homeroom teachers and the admissions office.

Scholarships
The school does not publicly disclose any scholarship programmes or financial aid schemes. No details are available regarding eligibility criteria, application procedures, or coverage.
