Constitution of the European Union Science Olympiad (EUSO)


This edition of the EUSO Constitution is based upon and reflects the philosophy, principals, structure, rules and regulations of the first EUSO Constitution devised and published in 2000 in five European Union languages by Dr. Michael A. Cotter, Founder of the EUSO. Since the establishment of the EUSO he has proposed and implemented a number of minor changes to the original Constitution. The title ‘European Union Science Olympiad’, the ‘EUSO Constitution’ and the ‘EUSO Logo’ are all registered with the European Union Intellectual Property Office.

1 – Mission Statement

The European Union Science Olympiad (EUSO) is a unique multidisciplinary, integrated science, practical-based, team competition for European Union (EU) second level school science students who are sixteen years of age or younger on December 31st prior to the competition. It provides young EU students with a platform to display their scientific capabilities, challenges and stimulates gifted EU science students to develop their talents and to promote their career as scientists, provides invaluable experience for EU students who may take part in the subject based international Science Olympiads, offers the opportunity to compare the syllabi and educational trends in science education within the EU member states which could help improve science education at national levels.

EUSO Experiments

The EUSO Tasks (experiments) are intellectually challenging and demand teamwork. They integrate the sciences biology, chemistry and physics across the disciplines. They are problem oriented, context-based, relevant and connected to the real world. The tasks engage all the team members and foster their ability of cooperative problem solving. They are self-directed in terms of pace, direction and outcomes. They involve the construction of knowledge and higher-order thinking. They require the interpretation of experimental data, facilitate the manipulation of information and ideas, encourage substantive communication between the team members and often allow for alternative solutions.

Objectives of the EUSO

–  to stimulate the active interest of students in the sciences and challenge science students to develop their talents.
– to promote and reward the pursuit of excellence in scientific endeavour by selecting the top young EU science student teams at the annual EUSO.
– to prepare EU science students for the subject based international Science Olympiads.
– to develop problem based material on experimental integrated science that may be used in EU secondary schools.
– to encourage greater contact and co-operation between secondary school students and teachers from the EU and to exchange ideas and materials about science education among EU states.
– to convey to students, schools and the community the importance of advanced study and progressive learning in science and – to raise interest in pursuing technical and scientific career paths.
– to encourage an appreciation of the value of science amongst the wider community and to foster a positive and high profile image of science and scientists.
– to provide an opportunity to foster European identity among EU students and mentors.

2 – EUSO Eligible Countries

The EUSO is open to all member states of the European Union (EU). Once a date is fixed by the EU for a country to become a full EU member, the President invites the Minister of Education/Science of an applicant EU member state to send an observer to EUSO in the year prior to joining the EU, with a view to attending with a full delegation 3 teams of 3 students, the CC and 2 mentors on becoming a full EU member.
The Ministry of Education/Science in the eligible country wishing to participate in the EUSO must nominate a Country Coordinator for the EUSO and communicate the name and contact details to the EUSO President. This is the only EUSO appointment that may be influenced by the Minister but the making of this nomination by a Minister is one of the conditions to be fulfilled by a country wishing to join EUSO. This eliminated the potential for competing agencies, universities, associations, societies, unions, etc. within a country to claim a right to select students to represent their country at EUSO,

3 – EUSO Host Country and Invitation

The EUSO is carried out in one of the participating countries every year in spring no later than end of April.
The EUSO is organised by the Ministry for Education of the hosting country, called the Organiser.
The Organiser of the EUSO has to ensure equal participation of all eligible countries. It invites all EU member states, which have either participated fully in or sent an observer to the EUSO in at least one of the three years prior to the competition, to send a full delegation. All other EU countries should be invited to send an observer.
The Organiser may invite Guest Delegations from the host country. The student teams of the Guest Delegations participate in the competition as additional teams. They may be awarded medals but their results are not considered during the determination of the numbers of gold, silver and bronze medals.
At least nine months prior to the EUSO the Organiser sends an official invitation to the Minister of Education/Science of the EUSO member countries and the Ministry of Education/Science of the non-participating countries.
The invited countries must confirm their participation six months prior to the EUSO.
Each participating EU-country is expected to indicate as soon as possible when it will host the EUSO.
In the event of the EUSO being cancelled all participating EU countries including those countries that had agreed to send an observer will be invited to send full delegations to the next EUSO.

4 – EUSO National Delegations

Each invited country may send a full delegation consisting of at most two teams of three science students each accompanied by a number of mentors. An EU country not eligible to send a full delegation may send an observer.

9 – Preparation for the EUSO

In each country participating in the EUSO training or any other special instruction that is carried out for a selected group of 50 or fewer students, containing the EUSO team members, should not be longer than two weeks in duration per school year.
Prior to the EUSO the Organiser should provide hints on topics covered or equipment used in the tasks that students cannot be expected to have encountered at school and/or that is not explained in sufficient detail in the tasks themselves.

10 – General Rules and Structure of the Competition

Structure of the competition
The EUSO competition is carried out within a period of 7/8 days including
– – day of arrival,
– – day for the opening ceremony and the discussion/translation of the first task,
– – day for the Task 1,
– – day for the discussion and translation of the second task,
– – day for the Task 2,
– – day for the moderation of the results,
– – day for closing ceremony and a farewell party,
– – departure day.
In case of a 7-day schedule the last three days may be compressed into 2.
The 2-part competition is spread over 2 days with an interval of at least 1 day.
The business of the EUSO meetings is conducted in English.
The display of national flags and emblems by the delegations at the opening and closing ceremonies is prohibited.

11 – EUSO Tasks, Evaluation and Awards

The Scientific Committee appointed by the Organiser of the hosting country is responsible for preparing the two tasks for the competition.
The Scientific Committee and the International Board agree the final English version of the Tasks
The International Board approve the final English version and all members are obliged to keep secret information about the competition tasks until all students have completed the tasks.

The students’ answers are independently assessed by the Scientific Committee and the respective Mentors.
At an agreed time the Country Coordinator and the Chairman of the Scientific Committee exchange team results. This facilitates the identification of possible common marking discrepancies and speeds-up moderation.
Before the determination of the awards possible discrepancies in the assessment are resolved in the moderation. During the moderation the Mentors of each country are allowed a given amount of time to discuss the scoring of the Scientific Committee with members of this committee. If no consensus can be reached within the allocated time the Mentors may request additional time at the end of the moderation schedule. If no consensus can be reached during the second allocated time, the Mentors may appeal to the EUSO President in the first instance and if not resolved satisfactorily the President may convene a extraordinary International Board meeting where the matter is adjudicated on. International Board makes the final decision.
The final results for each country have to be signed by the Country Coordinator or his/her nominee and a representative of the Scientific Committee.
Where a Country Coordinator or his/her nominee refuses to sign the results sheet of his/her country the Presidents signs the document to avoid delaying the closing ceremony.

Prior to the International Board meeting concerning the allocation of medals the Country Coordinators receive the final scores of their teams for confirmation.
The International Board must not be shown the actual scores of all teams but rather a list of numbers or a graph reflecting the ranking and differences between the team results. The numbers of medals to be awarded are determined on the basis of this data.
The numbers of gold, silver and bronze medals to be awarded are determined by the International Board according to the following percentages
– – Gold medals: approximately 10% of the contestants
– – Silver medals: approximately 30% of the contestants
– – Bronze medals: all remaining contestants
The total number of gold and silver medals combined must not exceed 50% of the total number of medals awarded.
The medals must be awarded during the official closing ceremony of the EUSO and are proclaimed on a team basis.
Bronze medal winners must be announced first in random order. The Silver medal winners must be announced next in reverse order, e.g. the team receiving the lowest score announced first. The Gold medal winners are then announced in reverse order with the top team being the last to be identified.
The team receiving the highest total score receives the Perpetual Challenge Trophy presented to the EUSO by Dr. Michael A. Cotter.
Each contestant receives a Certificate indicating the medal received and each Mentor and Observer must receive a certificate of participation at the EUSO

12 – EUSO Regulations

Countries taking part in the competition are obliged to comply with the EUSO Constitution.
Revisions to the Constitution, Guidelines Rules & Regulations become valid only after the completion of the on-going EUSO. Proposal for changes may be submitted to the EUSO President by Country Coordinators at least six months before the International Board meeting at which the changes are to be discussed. An agenda including the proposed changes must be circulated by the EUSO President to all Country Coordinators at least three months prior to the meeting.

Changes to the Constitution, Guidelines, Rules & Regulations must not interfere with the rights of any individual involved in EUSO.
