Who it fits — and who it does not

• Families set on the American pathway — it is a recorded curriculum family here.
• Families for whom budget is not the first constraint — its midpoint sits above the Bangkok Metropolitan median.
• Families whose children fit its span (3–18) — check the top year before shortlisting.
• Rail commuters — Phasi Charoen (MRT Blue) · 5.3 km is the nearest station ().

• Not a fit for boarding families — this is a day school in our records.
• Not a fit if the budget ceiling is hard: the published range tops out at ฿1,038,000 per year.
