General Statement

§ 1 - Aims of the competition

The International Chemistry Olympiad (IChO) is a chemistry competition for students at secondary school level with the aim of promoting international contacts in chemistry. It is intended to stimulate the activities of students interested in chemistry by a way of independent and creative solving of chemical problems. The IChO competitions help to enhance friendly relations among young people from different countries; they encourage cooperation and international understanding.

The official invitation to participate in the forthcoming IChO should be sent to countries by the November preceding the competition. The invited countries must confirm their participation in the IChO according to requirements of the organizer.

(3) Moreover, other countries may apply for the participation in IChO but the organizer has the right to invite the countries only on agreement with the organizers of two forthcoming IChOs.

§ 12 - Safety

(1) During the experimental part, the competitors must wear laboratory coats and eye protection. The competitors are expected to bring their own laboratory coats. Other means of protection for laboratory work are provided by the organizer.

(2) When handling with liquids, each student must be provided with a pipette ball or filler. Pipetting by mouth is strictly forbidden.

(3) The use of very toxic substances (designation T+) is strictly forbidden. The use of toxic substances (designation T) is not recommended, but may be allowed if special precautions are taken. Substances belonging to the categories R 45, R 46, R 47 must not be used under any circumstances (see Appendix B for definitions of these categories).

(4) The organizer provides a list of chemicals from which the chemicals used in practical preparatory and competition tasks are drawn. The list of chemicals must include information of the maximum amounts of materials needed or in the case of solutions their maximum concentrations. Any hazardous materials on the list must be accompanied by detailed instructions for safe handling. The list must be provided together with the preparatory tasks (see § 10).

Each participating country has three months to file a substantiated dissent concerning the use of a special chemical. Silence indicates acceptance. The organizer should try to revise the list in order to satisfy any objections. The final revision of the list will be distributed to the delegation leaders at the start of the Olympiad.

(5) Detailed recommendations involving students" safety and the handling and disposal of chemicals can be found in Appendices A 1, A 2, and B.

§ 13 - Competition Tasks

(1) The organizer is responsible for the preparation of competition tasks by competent experts/authors, who constitute the Scientific Board of the IChO. They propose the methods of solution and the marking scheme.

(2) The tasks, their solutions and the marking schemes are submitted to the International Jury for consideration and approval. The authors of the tasks should be present during the discussion.

(3) The Chair of the International Jury may put the Chair of the Scientific Board in charge of the proceedings when the tasks are considered.

(4) The total length of the theoretical or experimental tasks, answer sheets including should be kept to a minimum and not exceed 25,000 characters. The number of characters must be stated at the end of each exam paper. SI units must be used throughout the competition tasks.

(5) In the experimental part of the competition the following conditions must be fulfilled:

1. The experimental part must contain at least two independent tasks.
2. No part of the grade can subjectively be evaluated by the staff.
3. Competitors must receive the same substances when solving the tasks from qualitative analytical chemistry.         
4. When solving tasks from quantitative analytical chemistry competitors must receive the same substances but with different concentrations.
5. In evaluating the quantitative tasks the master values must not be based on average results of the competitors.
6. The great majority of the grade in quantitative tasks must be given to the mean value as reported by the competitors while some marks may also be given to the corresponding equations, calculations, or explanations directly related to the work. Points must not be awarded for reproducibility.  

§ 14 - Correcting and Marking

(1) A maximum of 60 points is allocated to the theoretical tasks and 40 points to the practical tasks, making a total of 100 points.

(2) The competition tasks are corrected independently by the authors and by the mentors. Consequential marking should be used so that students are not punished twice for the same error. Both corrections are then compared, however, the authors present their evaluation first. After a discussion the final score for each participant is reached and agreed by both sides. The organizer retains the original marked manuscripts.

(3) The International Jury discusses the results and decides on the final scores.

(4) In order to eliminate any doubts about possible mistakes in the processing of the results the organizer must provide the mentors with a list of their students' total results  before the closing awards' ceremony. 

§ 15 - Results and Prizes

(1) Official results of the competition and the number of medals awarded are decided by the International Jury.

(2) The number of gold medals awarded is in the range of 8% to 12%, silver 18% to 22%, and bronze medals 28% to 32% of the total number of competitors. The exact number of medals is decided on the basis of an anonymous review of the results.

(3) Every medalist must receive the medal and a corresponding certificate from the organizer.

(4) In addition to the medals other prizes may be awarded.

(5) An honorable mention is awarded to competitors who do not receive a medal, but gain full marks for at least one problem. 

(6) Each competitor receives a certificate of participation.

(7) In the awarding ceremony, the non medalists are called in alphabetical order.

(8) No team classification takes place.

(9) The organizer must provide a complete list of results as a part of the final report.

§ 16 - Final Regulations
