Trade-offs
- !Does NOT offer the IB Diploma — IB authorization covers PYP and MYP only, and the Upper School switches to Cambridge A Levels, so the 'IB' framing is a lower/middle-years method, not a Diploma outcome
- !No published IGCSE or A-Level results — academic outcomes cannot be independently verified
- !The ISI inspection on file dates to 2010 and no graded verdict is quoted; COBIS/IB give accreditation but not a public quality band
- !Relatively young Upper School (first Year 10 in 2018, first graduates 2021) — limited senior-school track record
- !No financial aid or scholarships are advertised, against premium fees (up to ~$67,800/year plus one-time enrollment and deposit costs)
- !Does NOT publish IB average scores or a verified university-destination list — the headline '80% accepted to highly selective colleges' is school-reported and unverifiable
- !Full IB PYP/MYP continuum is claimed by third-party directories but NOT confirmed on the school's own pages, which describe only an 'IB approach' culminating in the DP
- !Among the most expensive schools in the sample — Kindergarten–Grade 10 at USD 70,700 and Grades 11–12 at USD 72,000 for 2026-27
- !Boarding tuition is not published on the official site (third-party directories cite figures near USD 89,000–95,000 all-in, unverified)
- !The only public enrollment figure (~750) is a 2016-17 third-party number; no current official total is published
