Students in Grades 9 and 10 build a strong academic foundation across a broad range of subjects, developing the independent inquiry skills and reflective practice that underpin all four graduation pathways. Daily homeroom advisory and consultancy periods ensure personalised mentorship and that every student is known, supported, and guided throughout their high school journey.
The foundational MSA-accredited diploma, providing access to universities and employment worldwide. It can be personalised with IB Certificates in focused subject areas.
A rigorous, passion-driven pathway for students who want to go further. Combining a robust academic curriculum with personalised, high-level learning, it culminates in a comprehensive senior project presented before a panel of AISZ educators and external experts.
The globally recognised two-year pre-university programme, covering six subject groups, Theory of Knowledge, an Extended Essay, and CAS. AISZ students consistently outperform the world average, with an average IB grade of 5.2 against the global average of 4.9.
For students who wish to pursue targeted academic enrichment, this pathway combines the AISZ diploma with IB courses and exams in specific areas of interest.
All students also have access to PSAT, SAT, and MAP assessments, and benefit from dedicated Academic and University Counseling to guide their post-secondary journey.
