UK Chemistry Olympiad

Take part in the leading chemistry competition for secondary students across the British Isles

Designed to challenge and inspire, the UK Chemistry Olympiad is a unique opportunity for students to push themselves further and excel in the chemistry field.

Budding chemists will develop critical problem-solving skills, learn to think more creatively and get a chance to test their knowledge in new, real-world situations. They could even find themselves representing the UK at the prestigious International Chemistry Olympiad.

Sign in to register

Registration for round one of the UK Chemistry Olympiad 2024 is now open to all Teach Chemistry members.

You need to sign in to your Teach Chemistry account to register for the competition.

Who can enter the Olympiad?

The UK Chemistry Olympiad is open to all secondary schools and colleges in the British Isles. However, the questions are aimed at students in their last year of study before higher education so we recommend that entrants should be at least 16.

The competition is designed to challenge, so will not be easy. Students should see it as an opportunity to develop their thinking and problem solving skills, and to test their existing knowledge of chemistry in real-world situations.

How the Olympiad works

Run annually, the competition is made up of three stages that start with a written test and end with four students representing the UK at the prestigious International Chemistry Olympiad.

Registration

Wednesday 20 September 2023 – Sunday 7 January 2024

The first thing to do is register your school or college. Schools and colleges don’t need the names of the students taking part in order to register. Students wanting to register must do so through their school or college (see the FAQs section for more details).

If you are an accredited British international school overseas, the first thing to do is email us.

Round one written test

Thursday 25 January 2024

The first challenge for students is designed to test chemical knowledge through a written test with real-world chemistry problems. This round takes place at your school. We’ll email the test to teachers at the beginning of the test period with the mark scheme following later.

This stage often stimulates a lot of debate and conversation around what chemistry is all about, so it’s a great opportunity for your students to develop and showcase some of the skills they’ll need at university and beyond. It’s open to every institution teaching students aged 16–19 years in the British Isles. (Please note that we are only able to issue certificates to students aged 19 and younger.)

Round one marking

Friday 26 January – Friday 9 February 2024

We’ll release the mark scheme to schools after the round one written test. Teachers mark all papers in school and then submit the scores to us. We’ll ask that you post us physical copies of all papers that scored particularly highly. We recommend making copies of any papers you post and keeping all papers until you have received the results as we may ask for others in spot-checks.

After receiving all your scores and papers, the exam moderators meet to spot-check the marks and select 25–30 students from all entries to move on to round two.

Round two

Thursday 4 – Sunday 7 April 2024, University of Nottingham

Round two is a stimulating long weekend of training and assessments. Up to 30 of the highest-scoring students from round one will take part in lessons and demonstrations on new topics from respected academics, teachers and technicians, followed by theoretical and practical assessments. Download our guide to find out more about how round two works.

Four students from round two will be chosen to represent the United Kingdom at the International Chemistry Olympiad.

UK training camp and the International Olympiad

Training between May and July 2024 | Finals from Sunday 21 – Tuesday 30 July 2024

After intensive training to prepare our competitors, we will take part in the International Chemistry Olympiad 2024 in Riyadh, Saudi Arabia – and hopefully come back with gold!

What teachers and students say about the Olympiad

‘This really enhances a love for the subject and I have several students now seriously considering a career and degree in chemistry, which would not be the case without this competition.’

_{Teacher, 2018 Olympiad}

‘Not only was it a great experience, I feel like it will be a huge asset to my UCAS application.’

_{Student, 2018 Olympiad}

‘It is an enjoyable challenge to my chemistry knowledge.’

_{Student, 2018 Olympiad}

‘It can help make difficult A-level questions easier, as you get used to different, harder ways of asking questions, and so would be good preparation for the chemistry A-level exam.’

_{Student, 2018 Olympiad}

Frequently asked questions

I missed the deadline to register my school – will it still be possible to enter?

Unfortunately not. We have to move on to processing entries as soon as the deadline passes, so it’s not possible for us to accept late registrations.

Do I need to have the names of my students ready before I register?

No, we won’t ask for the complete list until you upload your scores.

Can I register as an individual student?

If you would like to take part in the Chemistry Olympiad, you must let your school or college know so that they can register on your behalf. We can’t accept registrations from students directly.

May I register a school from outside the UK?

The competition is free to schools in the British Isles. International schools in China can also enter, and should register through ASDAN China. Accredited British international schools overseas are eligible to enter and for these schools a fee is payable. Please email us if you think you are eligible to enter.

Are younger pupils allowed to enter?

Yes, however please bear in mind that the questions focus on topics typically covered in a student’s final year of study. Because of this, Year 12s who are confident in their knowledge could take part, but GCSE students may find the subject matter too advanced.

Is a professional invigilator required?

No – the class teacher or other member of staff can invigilate the exam.

Can you provide the exam paper in accessible formats?

Yes – if your students require the round one exam paper in braille please inform us by email by 15 November. Should you require the exam paper in large print, you will be able to enlarge the text in the electronic copy we send you.
