Découvre de nouveaux domaines de la chimie et comment participer : À propos de l'IChC

General Information

What is IChC?
Chemistry is the central science that bridges physics, biology, and materials science, exploring the composition, structure, and transformations of matter. From understanding the molecular basis of life to developing new materials and medicines, chemistry touches every aspect of our daily lives. The International Chemistry Competition embraces this spirit of discovery and gives students the opportunity to challenge their chemistry knowledge and to learn more about this fascinating subject beyond the typical school curriculum.
What makes IChC unique?
Internationality, Digital Accessibility, Real-World Research, Adjusted Difficulty, Online Tools for Teachers, Supportive Alumni Network, and more. All details are available here: About IChC
I have already participated. Should I participate again?
Yes, of course!
Are teams allowed?
Everyone has to submit their own solution papers in all rounds. However, for the Qualification Round, you are allowed to work on the problems with your friends and classmates together. Working together or receiving help from other people is not permitted in the Semi-Final and Final Round. You can find more about rules and cheating policy here: Cheating Policy
Where do I find the problems of last year's competition?
You can find them here: Training Problems
How can I prepare for the competition?
You can learn more here: Training Problems
What are the social media links of IChC?
Will there be verification codes on the certificates?
Yes, all of your IChC certificates have verification IDs. This enables others to verify the authenticity of the certificates and documents: Verification page
How does IChC compare to other science competitions? (e.g., IChO)
Comparing the International Chemistry Competition to other science competitions can be misleading: IChC does not intend to be an alternative to established competitions (e.g., International Chemistry Olympiad) or their national variations and actively encourages students to take part in such opportunities.

Instead, IChC serves as a supplementary program designed to engage a wide range of students, particularly those just beginning to develop an interest in chemistry and related scientific subjects. It focuses on accessibility, making it a platform for students of all skill levels to explore and grow their understanding of chemical phenomena and scientific reasoning.

Learn more on this page: About IChC
How is the International Chemistry Competition organized?
The International Chemistry Competition is an independent educational program. More information about the history, organization, and funding is available here: About IChC
How is this international competition funded?

The costs are covered by sponsors and partners as well as through the participants via the Semi-Final Round registration costs: More Information. Financial aid is available to assist socio-economically disadvantaged participants: Financial Aid.
Where is the competition located? What is the address of IChC?
The International Chemistry Competition takes place primarily online and is accessible to students around the world; you do not need to travel somewhere to participate. The organizing team is constantly evolving, with most team members and technical infrastructure being located in Germany. There are also many other people around the world, such as the IChC local ambassadors, who do their best to make this competition a valuable experience. More information and contact details are available here: Contact Information
What are there for study materials and resources?
The training page gives tips, book recommendations, and a comprehensive collection of problems from previous years: Training and Preparation. Additional resources and links related to chemistry are available here: Resources and Links. This also includes the following: Videos, Lecture Notes, Presentations, and Infographics. We also provide a list of special resources for teachers and educators: Teaching.
Where can I find all deadlines and important dates of this year's edition?
All details are available on the Process & Rounds pages, and a summary of all deadlines is available in this document: Timetable & Deadlines Flyer
Why can I not log into my participant account from last year?

The video shows you (from behind) doing the exam and the screen with you selecting the answers. Of course, it is also possible to film yourself from the side or any other angle (as long as you and the content on the screen are visible). Your face can be visible in the video, but this is not a requirement.
What should the photo show that my teacher has to take?
You can find examples here: Photo Examples ➚. The picture should show the exam conditions/environment. That means the student taking the exam / in front of the device and the device screen.
Can I skip questions and complete the exam under 20 minutes?
Yes, you can answer/skip a question in under 60 seconds.
Can I bring a blank piece of paper and a pen during the exam?
Yes, you are allowed to bring a blank piece of paper and a pencil for note-taking during the exam.
Does my family/household member need to register to film the exam?
No, if you choose the recording option, you only need to write down the name of the person. The person filming does not need to register somewhere.
I have no teacher to supervise the exam. What should I do?
Please use the recording option in this case. To do this, please start the exam during the exam period (see information flyer or e-mail) and select the recording option when the approval screen appears. You then have to specify a person filming the exam (you can also film yourself). You can find more information in the Final Round flyer and in the information video (see the announcement e-mail or your participant account).
Can I do the exam on my phone?
Yes, it is allowed to do the exam on your phone.
How does my teacher get the approval code?
The approval code will be displayed on the participant's screen after they log in to the Final Round Exam platform. Then, the teacher must enter the code into a form that appears in their account.
Do teachers need to enter the approval codes of all participants?
If a teacher supervises multiple students at once and the participants start the exam simultaneously, it is sufficient to enter only a single approval code if all participants arrive at the approval page in the Final Round Exam platform.
Does the teacher have to be a science teacher?
No.
How does the Final Round take place?
Participants who have solved the Semi-Final Round problems successfully are qualified to participate in the Final Round: a multiple-choice online exam with 20 questions. The exam will take place in the school of each Finalist, supervised by a teacher. All Finalists have to select a teacher who agrees to supervise the Final Exam. We will send all the required information to the selected teacher. The Final Exam has to be taken on the Tuesday, 9 June 2026 between 4-6 pm. You can also record the exam (self-recording option). In this case, no teacher is needed.
How many questions does the Final Round have?
The Final Round consists of a single online exam with 20 questions. Finalists have 60 seconds for each question. There are four possible answers to every question (only one is correct). A correct answer equals one point. The awards and prizes are given to the Finalists with the most points in the Final Round.
What kind of questions/topics will be asked in the Final Exam?
The exam consists of 20 questions. Most of them are knowledge questions that test your general knowledge in chemistry. All standard chemistry topics are included.
Who can supervise the Final Exam?
The person supervising your Final Exam must be an active teacher (i.e. not retired) at some officially recognized school or university, and the person must be able to prove his employment at a school and his teaching duty.
How can my teacher register?
Your teacher has to register online: Teacher Registration Page
Can you refer me to some teachers who can supervise my Final Exam?
Unfortunately, we cannot provide you with teachers who can take your Final Exam. Please get in touch with the teachers of your school or teachers of other regional schools. Also, you can use the self-recording option in this case and conduct the exam yourself without a teacher.
Does the teacher have to be from my school?
No
How to qualify for the Final Round?
Please see 'Semi-Final Round' here: Process & Rounds
There are multiple Finalists in my school. Can we have the same teacher?
Absolutely yes. If there are multiple students that participate in the Final Round in your school, it is important that the same teacher takes the Final Exam for all students at the same time! Please contact your teacher and inform them about the other participants.
My teacher was rejected as a supervisor. What should I do?
Please ask another teacher who can prove to hold the exam as an independent authority. The rejected teacher can also register again with other documents (e.g., in case some information or documents are missing).
What help/tools are allowed for the Final Round?
You can bring blank paper and a pencil to take notes during the exam. No other tools are allowed. The computer/laptop/phone must only be used to open the Final Exam website.
What if two participants have the same number of points in the Final Round?
In this case, the results of the Semi-Final round and of the Qualification Round will be used to determine the final winner based on the total points. If the tie remains, both participants will receive the same award and split the cash prize. However, this has never happened before.
When will the final winners be announced?
The results of the Final Round and IChC 2026 will be announced on Monday, 15 June 2026.
I had technical issues. Can I do the exam again or continue later?
No. You have to make sure that there is a steady internet connection during the exam and that your browser is up-to-date. You are responsible for any recording or filming mistakes. It is not possible to pause, continue or re-take the exam once you have started.
Can my teacher supervise me online (via Zoom, etc.)?
No. A teacher must supervise the exam in person. The teacher is not allowed to supervise you via an online call (for example, Zoom or Skype). If you do not have a teacher available, please use the self-recording option and record your exam.
How to collect my prize or award?
We will use international shipping to deliver all of the 1st, 2nd, and 3rd prizes; there is no need to travel somewhere. The national awards and final round honours will be sent digitally as a soft copy.

Ambassador Program

What are IChC local ambassadors?
The International Chemistry Competition involves students from around the world and extends far beyond the annual competition. Our official local ambassadors represent IChC in their schools, universities, cities, and countries. Local Ambassadors coordinate local groups, organize activities and promote IChC in their community. Being an IChC Local Ambassador allows you to inspire students for chemistry and to prove your skills as a coordinator in a global network.
How can others see that I am an amabssador without a certificate?
You have a public profile on our website, which clearly indicates your local ambassador role. Additionally, you are listed on our team page and also have an local ambassador email address. If needed for your activities, our team can also be contacted to confirm your local ambassador role.
How to add my local ambassador activities?
Please log in to your local ambassador account and click on 'Add Activity'. There, you can describe your activity and upload up to five pictures.
What are the responsibilities of local ambassadors?
As an IChC Local Ambassador, your mission is to spark curiosity for chemistry, deepen the interest in science among students, and support the IChC initiative in your region through the following key responsibilities:
  1. Promoting chemistry and science by organizing activities and raising awareness in your community.
  2. Building a local chemistry group by bringing together interested students and creating a space for ongoing activities.
  3. Increasing local participation by encouraging students from your school, city, or country to take part in IChC.
  4. Supporting participants by answering questions, offering guidance, and acting as a local point of contact.

How can I get my local ambassador certificate?
You can find a link to your local ambassador certificate in your local ambassador account. Please note that a certificate will be issued to active local ambassadors only (i.e., at least three added activities and at least one Semi-Final Round participant associated with your local ambassador profile) after the Semi-Final Round announcement (25 May 2026).
What is the requirement for receiving an local ambassador certificate?
A certificate will be issued to active local ambassadors only. You qualify as an 'active local ambassador' if you have at least three added activities and at least one Semi-Final Round participant associated with your local ambassador profile. Please inform participants to select your name during the submission process or forward your personal local ambassador submission link.
What are the local ambassador levels?
To award active local ambassadors with long-time experience, local ambassadors can rank up to five levels depending on their (i) commitment to IChC, (ii) contribution to raising awareness and assisting fellow students, and (iii) frequency of organizing local activities & events:
  1. Newcomer
  2. Experienced
  3. Accomplished
  4. Distinguished
  5. Honoured
What is the local ambassador score?
The local ambassador score is determined by 10×QR + 20×PF + 30×F where QR, PF, F are the total number of participants in the Qualification, Semi-Final, and Final round associated with you as an local ambassador. Participants from all previous editions are included. Participants can select their local ambassador on the submission form.
Will I stay local ambassador forever?
Once you are approved, you are local ambassador without the need to apply again in the future. However, the IChC team removes all inactive local ambassadors (no participants or activities) each year. If you have been removed but want to continue as an local ambassador, you must apply again.
Can I create an IChC social media page?
In general, we do not recommend creating a local IChC social media page as information published on the official IChC social media page is relevant to all participants, and a separate page might be misleading for some students. However, feel free to create local city- or school-level social media groups, etc., to encourage and coordinate your local IChC group.

Can local ambassadors receive financial support?
To support your continued outreach and local chemistry activities, IChC offers financial support to local ambassadors who actively encourage student participation in the International Chemistry Competition, particularly in the Semi-Final and Final Rounds. This financial support is intended to help you organize further local activities, support your chemistry group or club, produce promotional materials, or cover basic outreach expenses. It is intended to strengthen your ability to fulfil your role as an IChC Local Ambassador and inspire more students in your region.

The amount of financial support is based on the total number of confirmed Semi-Final Round participants associated with your local ambassador account, and the financial support will be provided after the conclusion of the Final Round each year. A minimum of 25 Semi-Final Round participants is required to be eligible for the Local Ambassador Engagement Support.

All local ambassadors receive a personal IChC e-mail address as a professional channel for communication. Our team will activate and contact you usually a few days after you have been accepted into the Local Ambassador Program.
Can local ambassadors participate in the Semi-Final Round for free?
No, however, active IChC Local Ambassadors are given priority consideration for financial aid to cover the registration costs for the annual Semi-Final Round of the competition. This support is intended to recognize and assist local ambassadors who have shown high commitment through outreach and participant engagement. Typically, local ambassadors who have successfully encouraged five students or more to participate in the Semi-Final Round of the current or last year's edition of IChC received financial aid. While financial aid cannot be guaranteed, local ambassadors with active profiles and documented outreach have significantly higher chances.

Participants must confirm their participation before they appear in your account or are credited to your local ambassador score. If they did confirm their registration, please ask them to make sure they have selected you as their local ambassador: Participants can change their local ambassador selection via their participant account until the Qualification Round deadline.
Do I need to submit a quarterly report?

This is in particular important if there is a National Local Ambassador in your country. You can upload the report via your local ambassador account and will receive a reminder e-mail. This report does not replace the need to add your activities frequently.
