Reading the fee schedule

How The Baht records school fees

Every figure comes from the school's own website or fee document, recorded with its URL and the date it was checked. Alternative or special-case one-off fees (per-family rates, boarding deposits, waiting-list fees) are listed on the school pages but not added into totals. Corrections: editorial@thebaht.com.
