Reply from Singapore International School @ Da Nang (SIS) to the editor by message, received 1 October 2026.
Answer to: "Học phí mầm non cả ngày đã bao gồm bữa trưa chưa ạ?" (Does the full-day kindergarten fee include lunch?)
The school's message, copied verbatim:

Tiền ăn đã bao gồm trong học phí, nếu mình gửi full day, vì prenursery vs nursery có chương trình gửi nữa ngày, nếu gửi full thì tiền ăn đã bao gồm

With the message the school sent its 2026-2027 kindergarten fee sheets (Integrated and International Kindergarten Programme, dated 23 January 2026) and a note on other fees, photographed at:
