What Are the Differences Between Australian, British and American School Curricula?
The main differences between Australian, British and American school curricula come down to four factors: how many subjects students study, how they are assessed, the teaching approach, and the qualifications they receive. These differences begin in the early years and become more pronounced as students progress through primary, middle and senior school. Australian students follow an inquiry-based curriculum from early years through to Year 12, earning an HSC and ATAR ranking. British students progress through the National Curriculum, IGCSEs and A-Levels with examination-focused assessment. American students experience continuous assessment throughout, with optional Advanced Placement (AP) courses in high school. All three pathways are internationally recognised by leading universities worldwide.
Moving to Singapore with your family? With over 90 international schools offering Australian, British, American and International Baccalaureate (IB) programmes, understanding the differences can feel overwhelming—especially if you’re coming from a country with a different education system entirely. This guide is designed for families relocating from countries like Hong Kong, India, Korea, Japan, China, Indonesia, and beyond, who may be unfamiliar with Western education systems. Rest assured, international schools in Singapore welcome students from all over the world—at AIS alone, students come from over 50 nationalities, creating a truly multicultural environment where every child can feel at home.
How the Curricula Differ Across Age Groups
Understanding curriculum differences is important from the earliest years, as teaching philosophies and assessment approaches shape your child’s learning experience from the start—not just in senior school.
Early Years and Primary (Ages 3-11)
In the Australian curriculum, primary years focus on eight learning areas: English, Mathematics, Science, Humanities and Social Sciences, the Arts, Languages, Health and Physical Education, and Technologies. Learning is inquiry-based, with teachers guiding students to explore concepts through investigation and discovery. Assessment is ongoing and formative, providing continuous feedback rather than high-stakes testing.
British primary schools follow the National Curriculum of England, with a structured approach to literacy and numeracy. Key Stage assessments at ages 7 and 11 measure progress against national standards. Some international schools offer the IB Primary Years Programme (PYP) as an alternative, which takes a more inquiry-based, transdisciplinary approach.
American elementary schools emphasise foundational skills in reading, writing and mathematics, with assessment through regular classroom tests, projects and standardised assessments. The approach tends to be student-centred with flexibility for different learning styles.
Middle School (Ages 11-16)
Australian middle school continues the inquiry-based approach through Years 6-8, with students studying a broad range of subjects. Some schools then introduce the internationally recognised Cambridge IGCSE programme in Years 9-10, combining the rigour of British qualifications with the breadth of Australian education. This blended approach gives students the best of both worlds—academic challenge through IGCSEs while maintaining the inquiry-based learning philosophy.
British middle school follows the National Curriculum through Key Stage 3 (Years 7-9) before students begin their IGCSE courses in Years 10-11 (ages 14-16). Cambridge IGCSEs are internationally recognised qualifications covering a wide range of subjects, assessed primarily through external examinations. In 2024, over 950,000 IGCSE entries were recorded from students in 140 countries, making it the world’s most popular international qualification for 14-16 year olds. This two-year programme prepares students for A-Level specialisation.
American middle school maintains a broad general education with continuous assessment contributing to cumulative grades. Students begin exploring electives and may be placed in advanced or honours classes based on ability.
Senior School (Ages 16-18)
This is where the curricula diverge most significantly in terms of structure and assessment.
The Australian Curriculum: Senior Years
The Australian curriculum is developed by the Australian Curriculum, Assessment and Reporting Authority (ACARA). In the senior years, students maintain breadth, studying 5-6 subjects through to Year 12. Assessment balances ongoing coursework (typically 50%) with final examinations (50%), giving students multiple opportunities to demonstrate their understanding.
The final qualification is the Higher School Certificate (HSC), which is converted to an Australian Tertiary Admission Rank (ATAR)—a percentile ranking from 0 to 99.95 that indicates a student’s position relative to all Year 12 students in Australia. In 2025, over 60,000 students received an ATAR, with a median score of 70.75. The academic calendar runs January to December, aligning with Asian school years—particularly helpful for families relocating from countries like Japan, Korea, or China.
Some Australian curriculum schools also offer Vocational Education and Training (VET) as part of the HSC, giving students access to practical, industry-relevant qualifications in areas like construction and hospitality alongside their academic studies.
This curriculum suits students who thrive with a balanced approach, want flexibility to explore different subjects, and prefer a mix of coursework and examinations.
The British Curriculum: A-Levels
After completing IGCSEs, British curriculum students narrow their focus to 3-4 A-Level subjects in Years 12-13. This specialisation allows for deep study in chosen areas, with highly qualified subject specialists delivering content-focused lessons.
Assessment relies primarily on external examinations, with A-Levels graded from A* to E in individual subjects. The depth of subject knowledge developed through A-Level specialisation can be advantageous for competitive university courses like Medicine, Law, and Engineering, where admissions tutors look for demonstrated expertise in relevant subjects.
The academic calendar runs September to July.
This curriculum suits students who already know their strengths and preferred subjects, and who perform well in examination-based assessment.
The American Curriculum: High School and AP
American high school students take 6-8 subjects with considerable elective flexibility, allowing them to explore diverse interests while meeting core requirements. Assessment emphasises continuous evaluation through projects, essays, presentations, and tests throughout the year, contributing to a cumulative Grade Point Average (GPA) on a 0-4.0 scale.
Students who want additional challenge can take Advanced Placement (AP) courses—college-level classes with standardised examinations scored 1-5. With over 250,000 students taking AP exams annually and a pass rate of approximately 62%, strong AP results can earn university credits, potentially shortening degree programmes.
The final qualification is a High School Diploma accompanied by GPA and AP scores. The academic calendar runs August to June.
This curriculum suits students who prefer continuous assessment over high-stakes exams, value extracurricular involvement, and are considering university in the United States.

The International Baccalaureate Option
Many families also consider the International Baccalaureate (IB), which offers programmes across different age groups:
The IB Primary Years Programme (PYP) is designed for students aged 3-12, using a transdisciplinary, inquiry-based framework that develops the whole child. Students explore six themes of global significance while building skills across traditional subject areas.
The IB Middle Years Programme (MYP) serves students aged 11-16, connecting academic study with the real world through eight subject groups and interdisciplinary learning. However, not all schools offer the MYP—some combine the Australian Curriculum or Cambridge IGCSE with IB Diploma pathways in the senior years.
The IB Diploma Programme (IBDP) is the senior qualification for students aged 16-19. Students study six subjects across different disciplines plus complete an Extended Essay (a 4,000-word independent research paper), Theory of Knowledge (TOK), and Creativity, Activity, Service (CAS) requirements. According to the International Baccalaureate Organisation, over 200,000 students worldwide completed the IB Diploma in 2025, achieving a global average score of 30.58 out of 45 and an 81% pass rate. The IB Diploma is highly regarded by universities worldwide, with approximately 70% of students at some schools choosing this pathway.
Blended Curriculum Approaches
Some international schools in Singapore offer blended approaches that combine elements from different curricula. For example, a school might follow the Australian Curriculum in primary and early secondary years, introduce Cambridge IGCSE in Years 9-10 to build examination skills, then offer both the IB Diploma and Australian HSC as senior pathway options.
This blended model can offer the best of multiple systems: the inquiry-based learning philosophy of Australian education, the internationally recognised rigour of Cambridge qualifications, and the flexibility to choose between IB or HSC in the senior years based on your child’s strengths and university goals.
Which Curriculum is Best for University Admission?
All three curricula are internationally recognised by leading universities worldwide, so the “best” choice depends on your child’s target destination and learning style rather than any inherent advantage.
The ATAR is accepted by universities in the UK (including Oxford and Cambridge), the United States (including University of California system), Canada, Singapore (NUS, NTU), Hong Kong, and throughout Asia-Pacific. Many universities offer scholarships for high-performing ATAR students, and the breadth of subjects studied can be advantageous for courses that value well-rounded applicants.
British A-Levels have particularly strong recognition in the UK and Commonwealth countries, and are accepted by over 600 US universities including all Ivy League institutions. According to UCAS, over 425,000 students were accepted to UK universities in 2024, with 82% receiving their first-choice institution. The depth of subject knowledge can be advantageous for competitive courses like Medicine and Engineering where admissions tutors look for demonstrated expertise.
American AP scores are accepted by over 500 universities in 75+ countries. Strong AP results can earn university credits, potentially shortening degree programmes by a semester or more. The American system’s emphasis on extracurricular activities and holistic applications aligns well with US university admissions processes.
The IB Diploma is accepted by universities in over 140 countries, with many universities offering advanced standing or credit for high scores. The programme’s emphasis on research skills, critical thinking, and community service aligns well with what universities seek in applicants.
How ATAR Compares to A-Levels and IB
Parents often ask how to compare an ATAR with A-Level or IB results. The key difference is that ATAR provides a single overall ranking while A-Levels and IB show performance in different ways.
ATAR is a percentile ranking—a score of 85.00 means the student performed better than 85% of all Year 12 students in Australia. It’s derived from the student’s best subjects in their HSC, with different subjects weighted according to their scaling. Universities set minimum ATAR cut-offs for different courses.
A-Levels are graded A* to E in each individual subject. University offers are typically made based on achieving specific grades in specific subjects—for example, AAB in Chemistry, Biology, and Mathematics for a medical course.
The IB Diploma is scored out of 45 points total, combining grades from six subjects (each scored 1-7) plus up to 3 bonus points from the Extended Essay and TOK. A score of 24 is the minimum pass; scores above 40 are considered exceptional.
All qualifications are well understood by international university admissions offices, and most universities publish conversion tables or entry requirements for each.
Can Students Switch Between Curricula?
Students can move between curricula, though the ease of transition varies significantly by age.
In Early Years and Primary (ages 3-10), transitions are generally seamless as the focus is on foundational literacy, numeracy, and social skills that transfer across systems. Whether your child has been in a British, American, Australian, or IB PYP programme, they can adapt to a new curriculum with minimal disruption.
In Lower Secondary (Years 6-8), transitions remain manageable with some adjustment time for different teaching styles and content sequencing.
In Upper Secondary (Years 10-12), switching becomes more challenging as students begin formal qualifications—HSC, IGCSEs, A-Levels, IB, or AP courses—that typically span two years. Changing mid-course may interrupt qualifications and require catching up on subject-specific content. If your family may relocate during these years, consider starting with a curriculum you can continue, or choosing the International Baccalaureate, which is the same programme worldwide.
Choosing the Right Curriculum for Your Child
When selecting a curriculum, consider your child’s age and learning stage. For younger children, focus on the teaching philosophy and approach—does your child thrive with structured learning or open-ended inquiry? For older children, think about assessment style and subject breadth.
Consider your child’s learning style. Students who thrive with continuous feedback and varied assessment often do well in Australian or American systems. Those who perform best with clear structure and examination-based assessment may prefer the British system or IGCSE pathway.
Think about subject preferences. If your child already has clear academic strengths and career goals, the British system’s specialisation may suit them. If they want to keep options open or haven’t yet discovered their passion, Australian or American curricula offer more breadth.
Consider your likely university destination. While all curricula are globally recognised, British A-Levels have particularly strong recognition in the UK; American AP aligns well with US admissions processes; Australian ATAR is well-recognised across Asia-Pacific and accepted by top universities in the UK and US; the IB Diploma is recognised in over 140 countries.
Finally, consider family mobility. If your family may relocate again, curriculum continuity matters. The IB is particularly portable as it’s identical worldwide. Australian schools follow a January-December calendar that aligns with Asian academic years—helpful for families from Japan, Korea, China, or other countries with similar school year timing.

English Language Support for Non-Native Speakers
For families relocating from countries where English is not the primary language, English proficiency support is a crucial consideration when choosing an international school. Many schools offer dedicated programmes to help students develop the academic English skills needed to succeed in the classroom.
At AIS Singapore, students have access to a comprehensive range of English language support options tailored to their age and proficiency level:
The English as an Additional Language (EAL) programme provides ongoing support for students who need help developing their English skills while studying in mainstream classes. Students are assessed during the enrolment process and placed in appropriate support levels—from beginner through to consolidating phases. In elementary school, this may include withdrawal classes with dedicated EAL teachers. In secondary school (Years 6-8), a co-teaching model provides EAL support within mainstream Humanities and Science classes, ensuring students don’t miss core content while building their language skills.
The Intensive English Stream (IES) is designed for elementary students (ages 6-11) who need more comprehensive support. With over 26 hours of weekly English instruction, students typically progress to mainstream classes within 12 months.
The Preparation Course for Secondary (PCS) is a one-year intensive academic English programme for students aged 11-14 (Years 6-9). This face-to-face course develops academic English through Maths, Science, Language and Humanities, preparing students for mainstream secondary studies. The course runs in two sessions aligned with the school calendar (January-June and July-December).
The Foundational Academic English (FAE) programme offers a flexible, partially self-guided option for students who need foundational preparation before entering the PCS programme. Students receive weekly teacher guidance while working through content at their own pace, with SLATE testing after 10 weeks to assess readiness for the next stage.
These pathways ensure that students from non-English speaking backgrounds—whether from China, Korea, Japan, Indonesia, or elsewhere—can successfully transition into an English-medium international school environment without being held back academically.
