05 / ILO
Key dates, the fee, and what language the exam is in
Registration opens on the official portal on 14 January 2027 and closes on 21 March 2027. The listed competition fee is US$50 per participant. ILO offers financial aid toward that fee for families earning under US$20,000 a year — the form and its 17 February 2027 deadline are on the official registration pages, and the aid covers the fee only, not mentorship or travel.
Thailand’s preliminary dates, announced with Beyond Code Academy, are 11 April 2027 for ILO Junior and 18 April 2027 for ILO Senior, at a regional venue in Central Bangkok. The official ILO pages quote a wider window — 10–11 April for Junior, 17–18 April for Senior — because dates vary by testing centre.
Both divisions sit the exam in English. Preparing at home in whatever language you speak is completely normal; what matters is that your child can read the problems and write the solutions in English under timed conditions.
