ACS (International), Singapore

The school is guided by Christian principles and a dual heritage that emphasizes character development, leadership, and service. It utilizes the IB Learner Profile and the school’s IGNITE values to foster a holistic environment where students are encouraged to excel academically, socially, and spiritually. The House system is central to this philosophy, providing a supportive community that promotes personal growth and social responsibility.

The school offers a structured academic pathway: Years 1 and 2 follow a general curriculum including English, Mother Tongue or foreign languages, Mathematics, Science, Humanities, and the Arts. Years 3 and 4 offer the IGCSE programme, with options for Foundation IB or Pre-IB courses for students preparing for the senior level. Years 5 and 6 culminate in the International Baccalaureate Diploma Programme (IBDP), which includes six subjects and the IB Core of Theory of Knowledge, the Extended Essay, and Creativity, Activity and Service (CAS).

The school prepares students for higher education through the IB Diploma Programme and IGCSE examinations. Graduates are supported by a long-standing alumni network and are encouraged to pursue diverse future pathways, with the school offering specific scholarships for students entering the IBDP.

The school provides academic support through subject teachers and House Tutors, with additional revision sessions typically offered after school on Tuesdays and Wednesdays. A dedicated International Student Pastoral Care Coordinator supports international students, and the House system serves as the primary network for pastoral care and student guidance.

Applicants must submit an online application with academic transcripts, birth certificates, and relevant identification. Admission is determined by subject-specific entrance tests in English, Mathematics, and Science, followed by an oral interview with senior staff. Students applying for Year 1 or Year 5 may alternatively use PSLE or O Level/IGCSE results for entry. International students are required to appoint a guardian and reside in approved hostels, such as ACS Oldham Hall or ACS Independent.

The school operates on an academic calendar that includes scheduled terms, examination periods, and designated holidays. Specific dates for events, assessments, and term breaks are maintained in the official school calendar available on the school's portal.
