About ISS International School
ISS International School is located at 21 Preston Road, Singapore 109355, offering international school education in Singapore. The school is KakiList-verified and ACRA-registered. No Google reviews are currently available for this listing, so independent rating data cannot be cited. No EduTrust certification has been confirmed in the provider data, which is a required credential for international schools regulated by the Committee for Private Education (CPE).
When considering ISS International School, prospective families should clarify the full cost picture: annual tuition fees at international schools in Singapore typically range from S$25,000 to S$60,000 or more depending on year group and curriculum. Beyond tuition, confirm the non-refundable enrolment fee (typically S$3,500–7,500), the refundable deposit (often equivalent to one term's fees), any building fund or capital levy, plus transport (S$3,500–8,000 per year) and meals (S$1,500–4,000 per year). Ask about the curriculum track offered — whether IB Diploma, American AP, British IGCSE and A-Levels, or another pathway — as this directly shapes university admission outcomes. Enquire about the student-teacher ratio, SEN capacity, and the proportion of expat versus Singaporean students enrolled. Attend an open house or school visit and, for older students, expect an intake assessment as part of the enrolment process.
To take the next step, contact ISS International School directly by phone or via the enquiry form on their listing to request a school visit, confirm the curriculum and annual cost breakdown, and ask about current availability for your child's year group.

Annual tuition at international schools in Singapore typically ranges from S$25,000 to S$60,000 or more, varying by year group and curriculum. ISS International School has not published specific tuition figures on this listing, so you should request a full fee schedule directly. Beyond tuition, budget for a non-refundable enrolment fee (typically S$3,500–7,500), a refundable deposit (often one term's fees), a building fund or capital levy at some schools (S$10,000–25,000), transport (S$3,500–8,000 per year), and meals (S$1,500–4,000 per year). Tuition fees are GST-exempt. Note that some schools have increased fees by 8–12% annually in recent years, which is a meaningful consideration over a multi-year enrolment.

The curriculum track offered by ISS International School has not been confirmed in the current listing data. Prospective families should ask directly whether the school offers the IB Diploma, American AP, British IGCSE and A-Levels, or another pathway, as each leads to different university admission strengths. The IB Diploma is broadly accepted by universities worldwide. The AP curriculum is particularly strong for applications to US universities. British A-Levels carry significant weight for UK university admissions. Clarify the school's published outcomes — such as IB average scores, AP pass rates, or university destination data — before making a decision. Ask about class sizes and the student-teacher ratio, which typically runs 16–20 at international schools in Singapore.
The typical enrolment process at an international school involves submitting an online application, attending a school visit or open house, and — for students in older year groups — completing an intake assessment. Waiting lists are common, particularly at popular entry points such as Year 7 to Year 9. Before paying any fees, confirm what is refundable if your family needs to leave Singapore mid-year, and get the full cost breakdown — including the enrolment fee, refundable deposit, and any building fund treatment — in writing. It is advisable to visit the school during normal hours and meet the relevant year-group lead before committing. Contact ISS International School by phone or via the enquiry form to enquire about current availability for your child's year group.
