The International Chemistry Competition (IChC) is an online competition with Qualification, Semi-Final and Final rounds. The official website currently publishes 2026 results and a completed submission period. No 2027 calendar, fees or cycle-specific eligibility reference dates were announced on the checked pages as of November 4, 2026.
Historical 2026 applications: The Rounds page gives March 29, 2026 at 23:59 UTC+0 for qualification solutions. Qualification entry was free. Qualified students could request limited financial aid by April 20 and register for the €12 Semi-Final by May 5 at 23:59 UTC+0. That registration clock comes from the 2026 flyer's timetable, printed page 11; the Rounds page itself omits it. Aid included limited 50% reductions and full fee waivers, without a guarantee. The research paper was released May 8; participants chose a supervised 60-minute exam between May 10 at 00:01 and May 12 at 23:59 UTC+0. The separate Final was June 9, 2026, described as around 30 minutes on the Rounds page.
Published 2026 eligibility covers current school and university students worldwide. The age-group page uses grade/age on March 29, 2026: Junior is grade 10 or below and under 16; Youth is grades 11–13 or age 16+; Senior is university year one or higher, or age 19+. The linked 2026 flyer instead describes Youth as grades 11–13 and under 19. Advancement thresholds also differ: the age-group page lists 12/14/17 qualification points and 7/9/11 Semi-Final points, while the detailed Rounds page/flyer list 15/17/20 and 8/10/12. These official differences are unresolved historical instructions, not confirmed eligibility for a new cycle.
The earlier expectation of another March–June schedule does not establish 2027 dates. Future dates, fees, funding and eligibility remain unknown until a cycle-specific announcement.
