ACS International - Singapore

The international arm of the Methodist ACS family in Singapore, running IGCSE plus IB Diploma in a Christian co-ed setting on Jalan Hitam Manis.

ACS International is owned by the Methodist Church of Singapore and sits at 61 Jalan Hitam Manis. The school takes students from Year 1 to Year 6 in the Singapore secondary system, sitting Cambridge IGCSE in Years 3 and 4 then IB Diploma in Years 5 and 6. Headmaster Gavin Kinch leads around 1,077 students. The November 2024 IB cohort averaged 38.34 against a global mean of 30.58, with a 100 percent pass rate.

Parents praise strong pastoral care, a settled house system and a parent community that organises itself well. Christian values run through the school and chapel is a weekly fixture, which suits some families and rules the school out for others. The recurring criticism is administrative inconsistency at senior level, and some families have flagged social and bullying dynamics in the older year groups. ACS competes directly with UWCSEA, Tanglin and SAS for IB-track Singapore families.

• Parents repeatedly point to pastoral care and the house system. "The house system is very strong," one parent said, citing leadership and CCA opportunities alongside small class sizes.
• Christian-school identity comes up as a draw, not a footnote. One parent said the "emphasis on values and character is what we love most"; another described a "holistic and Christian environment" that suited their children.
• Fees are framed as competitive within the IB tier. Multiple parents call them "more reasonable than other top tier IB schools", though local commenters still describe them as exorbitant.
• IB outcomes are a recurring talking point in Singapore school discussions, with commenters citing high full-mark rates among ACS International cohorts.
• The Singaporean intake shapes the social mix. Commenters note the school must keep 50-65% Singapore students and that local families use it as an alternative route to ACS Independent or SJI.
• Negative feedback exists but is uneven. One parent reported a vice principal who failed to respond to basic procedural questions; another flagged dismissive treatment in a specific class. Bullying surfaces in some student accounts.
• Teacher-side commentary hints at recent change at the school and pay disparities between expat and local staff.
