Home Competitions Chemistry Jan 21 2027 UK Chemistry Olympiad UKChO rewards a different skill set from U.S. contests: instead of testing recall, it drops students into an unfamiliar research scenario and asks them to transfer A Level/AP-level principles into it. For Irvine students targeting selective U.S. STEM programs or the UK's G5, it is an efficient addition — low friction to enter (sat at school, two hours), a generous certificate rate of roughly two-thirds, yet a gold that still discriminates meaningfully, and it evidences exactly the literature-reading and reasoning skills that read well in essays and in a chemistry-focused activity list. One caveat: overseas entrants can only sit Round 1 and cannot progress to UK team selection, so treat it as an academic credential rather than a route to a national team. High Open to secondary schools and colleges across the British Isles. The RSC advises entrants be at least 16; the paper suits Year 12-13 students, and GCSE-level students will find it hard. Entry is by school, and the supervising teacher needs an active RSC Teach Chemistry membership. Overseas schools can take part in Round 1: schools in mainland China, Hong Kong, India, Indonesia, Japan, Kazakhstan, Malaysia, Mongolia, Myanmar, Pakistan, the Philippines, Republic of Korea, Saudi Arabia, Singapore, Thailand, the UAE and Vietnam register via the RSC's designated partner ASEEDER China; British international schools elsewhere that teach in English following iGCSE/A Level or the IB may apply directly to the RSC for a fee. Only UK-based students progress to Round 2 and UK team selection. Register by Jan 11 → Dates to be announced
TBA U.S. National Chemistry Olympiad USNCO is the most credible chemistry competition in the U.S. pipeline, run directly by the American Chemical Society rather than by a commercial organiser, and admissions readers recognise what it signals. Simply qualifying for the National Exam demonstrates top-tier chemistry ability against national peers, while Honors, High Honors or a Study Camp invitation becomes a powerful academic marker for applications to selective STEM programs in chemistry, biochemistry, chemical engineering and pre-med. For families in Irvine there is a practical advantage too: Southern California's ACS local sections are well established and many local high schools already participate, so the first two rounds can be completed close to home. High Open to students in grades 9-12 who are U.S. citizens or lawful permanent residents (green-card holders), have been enrolled in an American school for at least one year, and are under 20 years old. Students cannot sign up individually; entry is arranged through the school's chemistry teacher and the regional ACS Local Section. →
