IB, British, American and Australian routes coexist
Singapore's international-school market does not run on one curriculum. The International Baccalaureate is offered across primary, middle and diploma stages at multiple schools, British-style routes commonly lead from Cambridge IGCSE into Cambridge or Pearson Edexcel International A Levels, American-style schools often use a high-school diploma alongside Advanced Placement courses, and Australian pathways including the HSC also operate.
No neutral, current dataset establishes market share by curriculum, so families should avoid assuming one system is dominant. Universities do not automatically treat all qualifications the same way: Singapore's National University of Singapore sets defined entry routes for A Levels from named boards and specific International Baccalaureate subjects, while UK admissions bodies generally accept International A Levels alongside domestic ones despite differing tariff treatment. The practical comparison is the school's actual subject menu and assessment route against likely university destinations, not the curriculum name on the prospectus.
