IMO 2019 Annual Regulations




We hosted the 60th edition of the International Mathematical Olympiad, on the 60th anniversary of the first IMO in Romania.

The IMO is the largest and most prestigious of all of the international olympiads, having grown from the original seven countries to over a hundred. The United Kingdom has participated since 1967 and has played host to the competition on two previous occasions (in 1979 and 2002). We were honoured to be able to invite teams from all over the world to celebrate the diamond anniversary of the founding of IMO.

Bath is a world heritage city renowned for its hot springs, Roman history and Georgian architecture. It was the home of the famous mathematician Adelard (his translations of Arabic texts on mathematics introduced the Hindu-Arabic numeral system to Europe). Contestants will be based at the University of Bath for the duration of IMO 2019. The university campus is situated on a hill above Bath, providing stunning views of the city and surrounding countryside. Contestants will be well looked after, with the dining room, recreational areas and the exam hall all within walking distance of the accommodation.

Members of the Jury were initially be located a short hop across the Severn Bridge in Wales. Wales is the birthplace of the equals sign. First used in a published text in 1557, Robert Recorde coined the use of a parallel pair of horizontal line segments to replace the phrase ‘is equal to’. Mathematicians, scientists, engineers and schoolchildren  have collectively saved many billions of hours of time in the years that have followed, for which we are all grateful.

The competition involved teams of up to six contestants sitting two exams on consecutive days. Each exam lasts 4.5 hours and contained three hard problems. Contestants’ scripts were marked over the next few days with each solution (or attempt) being awarded a score out of seven. Gold, Silver and Bronze medals were awarded just less than half of the contestants in the ratio 1:2:3. Those not within the medal boundaries, but achieving full marks on at least one problem, were awarded an Honourable Mention.

This unique event brought together the brightest young minds from around the world and represented, for them, the culmination of many years of mathematical endeavour and hundreds of attempts at solving problems. Our aim was to provide contestants with a comfortable environment so that they were be able to give of their best in the exams. We also wanted all participants to have opportunities to enjoy the company of like-minded young people from around the world and make memories and friendships that would last a lifetime.

Participation in the 60th anniversary celebrations extends beyond those able to attend the IMO. We are making resources available for our Diamond Maths Challenge, a team competition for younger participants. Details will be released soon.

  • BATH, ENGLAND - JULY 8, 2014: inside of Roman Baths with unidentified people, which is a site of historical interest in the city of Bath. The house is a well-preserved Roman site for public bathing


The 60th International Mathematical Olympiad will be held in Bath, United Kingdom in July 2019.
The main IMO site will be the University of Bath. The Leaders’ site will be the Celtic Manor Resort, with Leaders moving to the University of Bath after the exams.

Volunteers at IMO 2019


This should be read in conjunction with the IMO 2019  policies on

Data Protection,

Processing Personal Information,

Child Protection,

Policy on Recruiting Ex-offenders,

Health and Safety,

Volunteers had to be at least 18 years old at the time of IMO 2019.

These policies are were once still under construction, but now can be borrowed and improved by future IMO host countries.

If you wish to register early interest as a volunteer, get a time machine and set it for early 2019, and then send an email to volunteer@imo2019.uk with volunteer in the subject line. Please introduce yourself, explain your connection with maths or maths olympiads, and express a tentative interest in one or more of the categories of IMO2019 volunteer explained below. Keep it very short, because you may have to fill in a longer form later, and we don’t want you to duplicate your efforts unnecessarily.

While we welcome international volunteers, IMO 2019 is not able to provide financial support for international travel for volunteers. Also it is not able to assist with obtaining any necessary United Kingdom visas.

No mathematical background is needed for any of these roles. Any DBS checks which need to be made will be paid for by the IMO 2019 organization.


Team Guides

Each IMO team will have a team guide who will use their knowledge of how to function in the UK to make the IMO experience as pleasant as possible for their team and its leaders. In short, being a friendly face. Each country will bring a designated adult (usually the deputy leader) who is in loco parentis, so this is not the job of the team guide. The main functions of a team guide consist of giving advice, helping with language issues, transmitting information about arrangements from IMO2019 organizers to participants, and alerting IMO2019 organizers to any urgent problems which need to be resolved. Team guides must have a DBS check and provide references. There will be a Chief Guide who will set policy, and co-ordinate the team guides. Team guides will be resident at the University of Bath.

At previous IMOs, most team guides have been university students. Having foreign language skills (especially of languages less used in the UK) would be particularly useful (but guides who speak only English are also needed). It is important that Team Guides are responsible people, and that they actively enjoy the company of teenagers.

Team Guides must be available for training on 13th July and then resident (accommodation provided) at the University of Bath until 22nd July.


This task will involve working at the University of Bath.

Each IMO exam lasts 4 hours 30 minutes. A very large number of invigilators are needed in order to ensure the safe and secure sitting of the papers. Invigilators also facilitate communications between the IMO jury (Celtic Manor, Newport) and the exam site (the Sports Hall of the University of Bath). This will involve carrying and transmitting messages (questions of clarification etc), and scanning scripts. Some designated invigilators will have DBS checks (to assist students who are ill, and enter the designated exam toilet areas for security checks). There will be a Chief Invigilator who will co-ordinate and set policy for invigilators.

Monday July 15 is invigilator training day; Tuesday July 16 is contest day 1; Wednesday July 17 is contest day 2. The invigilation days will be long, and it will be an intense experience. However, it is a short commitment in terms of days, and vital to the successful functioning of IMO2019. At previous IMOs, invigilators have often been academics, schoolteachers or students. We are looking for enthusiastic, reliable and dedicated individuals who are determined to ensure fair play.

Administrative Personnel

We will need a team of administrators to handle all sorts of IMO activities (including registering arrivals, handing out documents, supporting communications and computing, giving advice on local geography, facilities and services, and anything else which may arise). Administrative help will be needed both at the University of Bath, July 14-22 (with Sunday July 14th being peak activity (students’ arrival day), and at Celtic Manor, Newport July 10th-17th, with peak activity on July 11th (leaders’ arrival day). DBS checks will be required since administrators may have access to personal information.

Accommodation may be provided, dependent on circumstances

Jury Guides
No mathematical background is needed.

A small team of energetic people are needed to facilitate the activities of the IMO jury. This is like a UN General Assembly. Microphone running (to facilitate speeches) is a key part of this role. Accommodation will be provided from Thursday 11th until Wednesday 17th at or near Celtic Manor Resort Hotel, Newport. No DBS check is needed. At previous IMOs, jury guides have often been students.

Ceremony Organizers

The IMO2019 opening ceremony will be in The Forum, a theatre in Bath on Monday 15th July. This will be a jovial affair, with a parade of the nations (many in national
costume), some entertainment, and as few speeches as possible. It is, however, vital that there is strict segregation between the jury site people (who have seen the exam papers), and University of Bath based people, who have not. Thus, as well as making the ceremony run smoothly, there is a policing aspect to crowd control. The closing ceremony will be at the University of Bath on Sunday 21st July. This is a more sober affair, with medals and presentations, and as few speeches as possible. Accommodation will be provided if necessary.

Transport (including a Director of Travel)

Coordinating meet and greet, both of team leaders (mainly on Thursday July 11) and students (mainly on Sunday July 14), and excursions (July 18,19). Accommodation will be provided as necessary. IMO 2019 has hired a coach company which will do a lot of the work, but we need IMO 2019 volunteers on hand to solve problems as they arise. This includes making sure that participants are met at points of entry to the UK, and their journies in the UK are as comfortable as possible. There is also the important matter of facilitating safe return journeys as participants leave the IMO on July 22nd.

People with design skills, typesetting skills, internet skills etc please make yourself known if you are prepared to volunteer to work in advance of IMO 2019.

Register an early interest (repeating the information at the top of this section)
If you wish to register early interest as a volunteer, send an email to volunteer@imo2019.uk with volunteer in the subject line. Please introduce yourself, explain your connection with maths or maths olympiads, and express a tentative
interest in one or more of the categories of IMO2019 volunteer expained above. Keep it very short, because you may have to fill in a longer form later, and we don’t want you to duplicate your efforts unnecessarily.
