The International Chemistry Olympiad (IChO) is a globally recognized Chemistry competition that is divided into practical and theoretical sections. Participants are required to adhere to guidelines set by the event's organizers. The Scientific Board of IChO develops the competition's tasks in the host country. Dubai, United Arab Emirates, will host the 57th IChO, expected in July 2025. Selection for the Olympiad is determined at the national level through each participating country's chemistry Olympiads. The highest-ranking four students from these national competitions are then chosen to represent their country at the IChO.
The official notifications for the 57th IcHO have been released on the official 2025 website. You can check the details here. The important dates (tentative) for the 57th edition of IChO 2025 in Dubai, United Arab Emirates are mentioned below:

The International Chemistry Olympiad (IChO) is held annually in July. In preparation, the countries involved receive the initial set of tasks by January, enabling students to begin preparing for the competition.
In this phase, students are provided with a set of preparatory problems designed to aid their preparation. This includes at least 25 theoretical and 5 practical questions that cover the three levels of difficulty previously outlined.
The competition consists of two stages:
Both parts of the competition are allocated five hours each, and materials are provided in the languages preferred by the participants to ensure clear understanding and accessibility.
The examination format for IChO 2025 is meticulously organized, encompassing chemistry's practical and theoretical facets. Below are essential highlights of the exam's structure:
The selection process for the IChO starts with the National Science Olympiad in Chemistry within each participating country. The foremost students advance to the international stage from this national competition to compete in the IChO. Each country must nominate 5 top students from their national Olympiads to participate in the IChO.
Awards at the International Chemistry Olympiad 2025 are presented to the highest achieving students, with gold, silver, and bronze medals awarded based on the participants' performance.
