- !Day school only, with no boarding option for relocating or regional families
- !No published government inspection band, so external quality signals rely on accreditation alone
- !No published fee schedule, so cost is opaque to prospective families

University Placement
School-reported · not independently verified
School-reported, unverified: ASB-published materials describe IB Diploma results and university destinations including highly selective US institutions; specific IB average scores and pass rates cited by third-party summaries could not be confirmed against a primary ASB source and are therefore not stated as verified figures.
School-reported, unverified: DAIS published an average IB Diploma score of 39.7/45 for the Class of 2025 against a worldwide average of 30.58, a 100% pass rate across all 110 candidates, five perfect scores of 45, and 61 students (55%) scoring 40 or above, with a mean grade of 6.2 versus a worldwide 4.9.
