What Is Korean Chemistry Olympiad (KChO)?
KChO is the Korean Chemical Society's advanced high-school chemistry education and selection pathway. It is not simply a one-day national contest. Students use official online education, sit a seasonal-school admission evaluation, and—if selected—join intensive Summer or Winter School cohorts organized for first- and second-year high-school students. The strongest eligible Winter School students continue into Korea's International Chemistry Olympiad selection.
For final IChO selection, a student must be under 20 on July 1 of the international-competition year and must have completed at least one year of secondary education while enrolled at a Ministry-of-Education-accredited school in South Korea. Final candidates come from the second-year Winter School cohort. Two Winter School exams cover both theory and laboratory work; final selection weights theory 40%, practical work 40%, and the Winter School admission evaluation 20%.
