Vietnam's free English olympiad on the ioe.vn platform; the 2026–27 school round for grades 1–9 is held in person on 26–29 November 2026.
IOE (Olympic tiếng Anh trên Internet) is run by VTC Online. Official rounds (school, ward/commune, province) are open only to students of schools that register to organise the contest; the 2026–27 school round is in person only, at a venue arranged by the school's supervisory board with on-site invigilators. The top 20% in each grade at each school (scoring at least 50%) receive e-certificates. Self-practice and official rounds are completely free.
