Welcome to IOAA 2016


Young astronomy students from 41 different countries of the world recently participated in the International Olympiad in Astronomy and Astrophysics. It was an opportunity for pre-university students from various countries to meet and make friends with students with similar interest from all part of the world. In this IOAA, 221 participants from 48 teams came and spent 10 days together competing and interacting with each other, from 9 to 19 December 2016.
India is one of the oldest countries in the world with its prehistory going back to almost 2 million years. It housed one of the earliest large scale civilisation, the Harappan civilisation from 7000 to 2000 BC and has not looked back. It is home to some of the finest architecture in the world from Taj Mahal to the magnificent Sun Temple at Konark, which the participants to the Olympiad visited.
India is also a vibrant democracy with a lot of interest and investments in pure sciences in general and astronomy in particular. Apart from several meter class astronomical telescopes, it hosts the world’s largest meter wave telescope and has recently launched a state of the art multi-wavelength astronomy telescope. Our hosting of the 10th International Olympiad in Moon Astronomy and Astrophysics was a part of our continuing tradition of encouraging young students to appreciate and enjoy the excitement of this oldest of pure sciences. The programme also offered an opportunity to meet Indian students beyond the participants through an active outreach programme associated with the event.
10th IOAA was hosted in one of the most picturesque and ancient city of Bhubaneswar, which boasts of a rich tradition of religious architecture, art form and cuisine. The city of Bhubaneswar, is also the capital of the state of Odisha. The host institute was National Institute for Science Education and Research (NISER).
For those of you who are new to the event, IOAA comprises of three rounds i.e. theoretical test, observation test and data analysis test, whose total counts towards medals of participating students. In addition, there was also be a team competition to determine the best team.

IOAA Statutes

Statutes of

International Olympiad on Astronomy and Astrophysics


In recognition of the growing significance of astronomy and related subjects in all fields of Science and Technology, including the general education of young people, and with the aim of enhancing the development of international contacts between different countries in the field of school education in astronomy and astrophysics, an annual competition in these subjects has been organised for high school students; the competition is called the “International Olympiad on Astronomy and Astrophysics” (IOAA). The International Olympiad on Astronomy and Astrophysics should be organised during the period of July – December.


The competition is organised in one of the participating countries on whose territory the competition is to be conducted. Participation in the IOAA is restricted to teams from countries or territories with National Olympic Committees, duly recognised by the International Olympic Committee, under the condition that they agree to abide by the Statutes of the IOAA and the decisions of the IOAA board, and appropriate international legal and diplomatic agreements. In the event of a dispute regarding the official name of a participating team, the name recognised by the International Olympic Committee will be used.

The organising country is obliged to ensure equal participation of all delegations, and to invite all the participants of any of the latest three competitions. Additionally, it has the right to invite other countries.

The International Olympiad on Astronomy and Astrophysics is a purely educational event. No country may have its team excluded from participation on any political ground resulting from political tension, lack of diplomatic relation, lack of recognition of some countries by the government of the organising country, imposed embargo and similar reasons. When difficulties preclude formal invitation of the team representing a country, students from such a country should be invited to participate as individuals.

Any kind of religious or political propaganda against any other country at the Olympiad is forbidden. A country that violates this rule may be barred from participation.

Within five years of its entry in the competition a country should declare its intention to be the host for a future Olympiad. This declaration should propose a timetable so that a provisional list of the order of countries willing to host Olympiads can be compiled. A country that refuses to organise the competition may be barred from participation, even if delegations from that country have taken part in previous competitions.


The competition is organised by the Ministry of Education or other appropriate institution of one of the participating countries. Hereunder, the term “Ministry of Education” is used in the above meaning.

The Ministries of Education of the participating countries, as a rule, assign the organisation, preparation and execution of the competition to a scientific society or other institution in the organising country. The Ministry of Education of the organising country notifies the Ministries of Education of the participating countries of the name and address of the institution assigned to organise the competition.


Each participating country sends one regular team consisting of high school students. Also students who finish their high school in the year of the competition can be members of a team. The age of the contestants must be less than twenty on June 30th of the year of the competition. Each team should normally have 5 students.

In addition to the students, two accompanying persons are invited from each country, one of which is designated as delegation head (responsible for the whole delegation), and the other – as pedagogical leader (responsible for the students). The accompanying persons become members of the International Board, where in they have equal rights. Members of the International Board are treated as contact persons for the participating countries concerning the affairs of the International Olympiad on Astronomy and Astrophysics until the following competition.

The competition is conducted in a friendly atmosphere designed to promote future collaborations and to encourage friendships in the scientific community. To that effect all possible political tensions among the participants should not be reflected in any activity during the competition. Any political activity directed against any individuals or countries is strictly prohibited.

The delegation head and pedagogical leader must be selected from scientists or teachers, capable of solving the problems of the competition competently. Normally each of them should be able to speak English.

The delegation head of each participating team should, on arrival, hand over to the organisers a list containing the contestants’ personal data (first name, family name, date of birth, home address and address of the school attended) and certificates (in English) from the schools confirming the contestants attendance or graduation in the year of the competition.


The organising country has the right to invite guest teams in addition to the regular teams (no more than one guest team per country). Normally the guest team consists also of five students and two leaders. However, the leaders of the guest teams are not members of the International Board. Except for that, their duties are the same as those of the leaders of the regular teams.

Participation of a guest team always needs approval from the organising country. The country sending a guest team pays all the expenses arising from its participation.

The next organisers are not obliged to invite guest teams present at the previous competition. Countries present with guest teams only are not obliged to organise the IOAA in the future.

Contestants from guest teams and guest teams are classified in the same way as regular teams. They may receive diplomas and prizes, their names should be identified with the letter “G” (“Guest”) in all official documents.


The working language of the International Olympiad in Astronomy and Astrophysics is English. Competition problems and their solutions should be prepared in English; the organisers, however, may prepare those documents in other languages as well.


The financial principles of the organisation of the competition are as follows:

The Ministry which sends the students to the competition covers the round trip travel expenses of the students and the accompanying persons to the place where the competition is held.

The Ministry of the organising country covers all other costs from the moment of arrival until the moment of departure. In particular, this concerns the costs for board and lodging for the students and the accompanying persons, the costs of excursions, awards for the winners, etc.


The competition consists of 2 parts: the theoretical competition (including short and long questions) and practical competition (including observations and data analysis). There should normally be 15 short and 2 or 3 long questions for the theoretical part. For the practical part, the organiser may give a set task on 1) observation, 2) paper-based practical problem, 3) computer-based problem, 4) planetarium simulation or combination of the four, which is expected to be solvable in 5 hours. The problems should involve at least four areas mentioned in the Syllabus.

The sequence of the competition days is decided by the organisers of the competition. There should be one free day between the two parts of the competition. The time allotted for solving the problems should normally be five hours for the theoretical part and five hours for the practical part. The duration of the Olympiad (including the arrival and departure days) should normally be 10 days.

When solving the problems the contestants may use non-programmable pocket calculators without graphics and drawing materials, which are brought by the contestants themselves. Collections of formulae from mathematics, chemistry, physics, etc., are not allowed.


The host country has to prepare 5 short and 1 long spare of theoretical problems and 2 spare practical problems. They will be presented to the International Board if some of the originally presented is/are rejected by two thirds of members of the International Board. The rejected problem cannot be reconsidered.

The competition tasks are prepared by the host country.


The theoretical part makes 50 % of the total mark, and the practical part 50 % (25% data analysis and 25% observation) of the total mark. The practical solutions should consist of theoretical analysis (plan and discussion) and practical execution. The solution to each problem should contain an answer and its complete justification.


The contestants will receive diplomas and medals or honorable mentions in accordance with the number of points accumulated as follows:

The mean number of points accumulated by the three best contestants is considered as 100%.

The contestants who accumulated at least 90% of points receive first prize (diplomas and gold medals).

The contestants who accumulate 78% or more but less than 90% receive second prize (diplomas and silver medals).

The contestants who accumulate 65% or more but less than 78% receive third prize (diplomas and bronze medals).

The contestants who accumulate 50% or more but less than 65% receive an honorable mention (diplomas).

The contestants who accumulate less than 50% of points receive certificates of participation in the competition.

In each of the categories above, through majority vote, the international board can adjust the position of cut-off up to two positions. i.e. include or exclude two students at the boundary of the respective category.

The participant who obtains the highest score (Absolute Winner) will receive a special prize and diploma.

Other special prizes may be awarded.


In addition to the individual classification one establishes the team classification according to the following rules:

Teams consisting of less than three contestants are not classified.

For judging the best team, a task to be performed by the team as a whole will be designed. This task may form either a part of the theory exam, practical exam, or be held at a different time. In case it is included in the theory or practical exam, the duration of the individual exam may be suitably reduced. The test may contain theory, practical or observation aspect or any combination thereof. The host country will be free to decide which option to use or propose a different format in consultation with the Secretariat. This should be announced to all participants in advance.


The obligations of the organiser:

The organiser is obliged to ensure that the competition is organised in accordance with the Statutes.

The organiser should produce a set of “Organisation Rules”, based on the Statutes, and send them to the participating countries in good time. These Organisation Rules shall give details of the Olympiad not covered in the Statutes, and give names and addresses of the institutions and persons responsible for the Olympiad.

The organiser establishes a precise program for the competition (schedule for the contestants and the accompanying persons, program of excursions, etc.), which is sent to the participating countries in advance.

The organiser should check immediately after the arrival of each delegation whether its contestants meet the conditions of the competitions.

The organiser chooses (according to the Syllabus) the problems and ensures their proper formulation in English and in other languages set out in # 6. It is advisable to select problems where the solutions require a certain creative capability and a considerable level of knowledge. Everyone taking part in the preparation of the competition problems is obliged to preserve complete secrecy.

The organiser must provide the teams with guides.

The organiser should provide the delegation leaders with Photostat copies of the solutions of the contestants in their delegation at least 24 hours before the moderation.

The organiser is responsible for organising the grading of the problem solutions and moderation.

The organiser drafts a list of participants proposed as winners of the prizes and honorable mentions.

The organiser prepares the prizes (diplomas and medals), honorable mentions and awards for the winners of the competition.

The organiser is obliged to publish the proceedings (in English) of the Olympiad. Each of the participants of the competition (delegation heads, pedagogical leaders and contestants) should receive one copy of the proceedings free of charge not later than one year after the competition.


The International Board is chaired by a representative of the organising country. He/she is responsible for the preparation of the competition and serves on the Board in addition to the accompanying persons of the respective teams.

All decisions, except those described separately, are passed by a majority of votes. In the case of equal number of votes for and against, the chairman has the casting vote.


The delegation leaders are responsible for the proper translation of the problems from English (or other languages mentioned in # 6) to the mother tongue of the participants.


The International Board has the following responsibilities:

To direct and supervise the competition to ensure that it is conducted according to the regulations.

To discuss the organisers’ choice of tasks, their solutions and the suggested evaluation guidelines before each day of the competition. The Board can change or reject suggested tasks but cannot propose new ones. Changes may not affect practical equipment. There will be a final decision on the formulation of tasks and on the evaluation guidelines. The participants in the meeting of the International Board are bound to preserve secrecy concerning the tasks and to be of no assistance to any of the contestants.

To ensure correct and just classification of the prize winners.

To establish the winners of the competition and make decisions concerning the presentation of prizes and honorable mentions. The decision of the International Board is final.

To review the results of the competition.

To select the country which will be the organiser of the next competition.

The International Board is the only body that can make decisions on barring countries from participation in the International Olympiad in Astronomy and Astrophysics for the violation of these Statutes.

Observers may be present at meetings of the International Board, but may not vote or take part in the discussions.


The institution in charge of the Olympiad announces the results and presents the awards and diplomas to the winners at an official ceremony. It invites representatives of the organising Ministry and scientific institutions to the closing ceremony of the competition.


The long term work involved in organising the Olympiads is coordinated by a “Secretariat for the International Olympiad in Astronomy and Astrophysics”. This Secretariat consists of the President and Secretary. They are elected by the International Board for a period of five years when the chairs become vacant.

The President and Secretary are members of the International Board in addition to the regular members mentioned in # 4. They are invited to each International Olympiad in Astronomy and Astrophysics at cost (including travel expenses) of the organising country.


These statutes are supplemented by:

Regulations concerning the details of the organisation.

The Syllabus mentioned in #18

Supplementary material (including Banner, Logo, Seal, Anthem, Publications, etc.)

Changes in the present Statutes, the insertion of new paragraphs or exclusion of old ones, can only be made by the International Board and requires qualified majority (2/3 of the votes).

Changes in the Supplementary material can be made by simple majority (1/2 of the votes).

No changes may be made to these Statutes, Supplementary material or Syllabus unless each delegation obtained written text of the proposal at least 3 months in advance.


Participation in the International Olympiad in Astronomy and Astrophysics signifies acceptance of the present Statutes by the Ministry of Education of the participating country.


The originals of these Statutes are written in English.

Supplementary Materials

The banner of the IOAA is made of blue silk cloth. Embroidered on it, in pink thread are the words “IOAA” in large capital letters. Above the words IOAA, a galaxy with 13 spirals is embroidered in yellow silk thread. On the right side of the galaxy the globe is embroidered in turquoise thread. Circularly underneath the word IOAA, the words “International Olympiad on Astronomy and Astrophysics” are written with small white letters. The lower oblique sides of the banner are decorated with several white tassels, either sides of the central tassel, which is yellow.

The logo of the IOAA was designed by Dr. Waspodo from Indonesia. It consists of the small letters “ioaa”. All letters are green, except for the second letter, which is a solid orange disc, depicting in the centre, a white spiral with three upper arms and four lower arms. The dot of the first letter is orange.

The basic pattern of the seal of the IOAA is similar to the logo. Circularly around the logo, as described above, the words “INTERNATIONAL OLYMPIAD ON ASTRNOMY AND ASTROPHYSICS” are written with capital letters. A solid dot separates the last letter of the word “ASTROPHYSICS” and the first letter of the word “INTERNATIONAL”.

The anthem of IOAA is the musical work entitled “IRIS”, composed by Vassilis Tassoudis from Greece. It was accepted by the International Board on 8th August 2013 during the 7th IOAA at Volos, Greece. The score of this anthem has been deposited at the IOAA headquarters.

The banner, the logo, the seal and the anthem of the IOAA are collectively or individually referred to as “IOAA properties”.
