About Razum International School (now Astor)
Razum International School, now operating as Astor, is an international school located at 1 Kay Siang Road, Singapore 248922. The school is KakiList-verified and ACRA-registered. No Google reviews are currently available, so independent rating signals cannot be assessed at this time.

When exploring enrolment, families should first establish which curriculum track the school offers — whether IB Diploma, American AP, British IGCSE and A-Levels, or another pathway — as this will determine university admissions outcomes for different national systems. It is worth requesting the full cost breakdown at the outset: annual tuition, the non-refundable enrolment fee, refundable deposit, any building or capital levy, and estimated transport and meal costs, as these together represent the true annual commitment. Families should also ask about the school's intake assessment process for their child's year group, current waitlist position, SEN provision, and the student-to-teacher ratio. Visiting the school during operating hours and meeting the relevant year-group lead before committing is strongly advised.
To begin the process, contact Razum International School (now Astor) directly by phone or via the enquiry form to confirm the current curriculum offering, EduTrust certification status, available places in your child's year group, and the complete fee schedule.

Annual tuition at international schools in Singapore typically ranges from S$25,000 to S$60,000 or more depending on the year group and curriculum. The school has not published its fee schedule on this listing, so families should request a full breakdown directly. Beyond tuition, the true annual cost at most international schools includes a non-refundable enrolment fee (typically S$3,500–7,500), a refundable deposit (often one term's fees), a building 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). Fee escalation of 8–12% annually has been observed across the sector, which is worth factoring into a multi-year commitment. Tuition fees are GST-exempt.

The curriculum track offered by Razum International School (now Astor) is not specified in the current listing data. Families should confirm this directly with the school before assessing fit. As a general guide, the IB Diploma is broadly accepted by universities worldwide and suits families who may relocate; American AP is strongest for US university admissions; British IGCSE leading to A-Levels is the established pathway for UK universities; and the Canadian Ontario curriculum offers flexibility for North American institutions. Each track has meaningfully different implications for where a student can apply and how competitively. Families should ask whether the school publishes IB average scores, AP pass rates, or university destination data for recent cohorts, and request the student-to-teacher ratio for the relevant year group.
The typical international school enrolment process involves an online application, a school visit, and — for older students — an intake assessment to confirm year-group placement. Families should ask about current waitlist positions, particularly for popular entry points such as Year 7 to Year 9, where competition for places is often highest. Before paying any fees, confirm what is refundable if circumstances change and you leave Singapore mid-year, how the building fund is treated on departure, and the exact timing of when the enrolment fee and deposit fall due. It is strongly recommended to visit the school during operating hours and meet the year-group lead before committing. Given that no EduTrust certification is recorded in this listing, verifying the school's current CPE registration status should be the first step in the process.
