With, and only with, the permission of the Chair, Official Observers may attend meetings of the Jury, but will not be permitted to speak or to vote. After the Contest, Deputy Leaders are welcome to attend meetings of the Jury. The Head Problem Coordinators shall attend meetings of the Jury as observers. They may be requested to comment on the selection of the problems.
      Only Leaders may vote. Each Leader shall have ONE vote. A motion shall be carried by a simple majority of votes. In the event of a tie, the Chair shall have a casting vote.
      The Jury may appoint subcommittees to consider specific matters.
      To facilitate proceedings, the working language of meetings of the Jury shall be ENGLISH. Leaders may at any time (in particular, before any vote) request translations into French, German and/or Russian.
    Before the Contest
    Before the Contest, the Jury shall :
      verify that all Student Contestants comply with the eligibility conditions prescribed in 2.2 above,
      confirm that four and one half hours will be allotted to the first examination paper of three problems, and that four and one half hours will be allotted to the second examination paper of three problems,
      confirm that each problem will be scored out of a maximum of seven marks,
      confirm that the total number of prizes will NOT exceed one half of the total number of Student Contestants participating; that the total number of first, second prizes and third prizes will be distributed in a ratio closely approximating 1:2:3.
      confirm that no prizes will be awarded other that first prizes, second prizes, third prizes, and special prizes for particularly meritorious solutions (see section 4.5 (e)), and that a certificate of honourable mention shall be awarded to each Student Contestant who does not receive a prize and who has obtained full marks on at least one question,
      select the Contest problems from amongst the submitted proposals on the basis of a preliminary selection made by the Problem Selection Committee, and
      approve the translations of the chosen problems into all required languages.
    The Contest
      The Contest will be run under the authority of the Chief Invigilator, who shall be responsible to the Academic Committee.
      The Contest will take place at York University in Metropolitan Toronto on Wednesday, July 19 and Thursday, July 20, each examination beginning at or about 9:00 am Eastern Daylight Time and ending 4-1/2 hours later at or about 1:30 pm Eastern Daylight Time. Contestants will not be permitted to leave the examination rooms during the first half hour or the last fifteen minutes of either examination.
      Members of the Jury shall ensure that no Student Contetant has, to their knowledge, advance knowledge of any problem proposed, and that all examination problems and solutions are kept strictly confidential to the Jury until after the examinations are written.
      Each Student Contestant may submit solutions in the language of his/her choice. Solutions may be written only on paper provided by the organizing committee.
      Each Student Contestant must work independently. Violation of this provision will result in disqualification of the Student Contestant from the Olympiad.
      Student Contestants are NOT permitted to bring any books or papers into the examination rooms. The only instruments permitted in the Contest are writing and mechanical drawing instruments. In particular, the use of books, notes, tables, calculators and other aids to calculation are not permitted. No books, papers, tables, calculators and computers may be brought into the examination room. Any Student Contestant making use of any prohibited item may be disqualified from the Olympiad.
      Student Contestants must submit all paper used. Pages to be considered by the markers must be submitted in the folder or envelope provided for this purpose. Pages to be scrapped will be left on the desks. Student Contestants may remove only their personal belongings and one copy of the question paper from the examination room.
    Queries by the Student Contestants
    During the first half hour only of each examination period, each Student Contestant may submit, on special notepaper provided, written questions for consideration by the Jury. A copy of each question shall be given, first to the Chairman of the Jury, and then to the Leader of the country from which the student comes. The Leader will propose an answer. If the Jury approves the answer, the Leader will write the answer on the copy of the Student Contestant's question.
    This copy shall then be given to the Chairman of the Jury for verification before a copy is returned to the Student Contestant who submitted the question.
    The Jury may decline to answer any question that it deems out of order, in which case the Student Contestant shall be informed that there is no answer.
    After the Contest
      The Student Contestants' solutions will be assessed first by their Leader and Deputy Leader, who will be guided by the marking schemes provided by the Chief Coordinator and the Head Problem Coordinators. Observers may attend a coordination session only with the prior permission of the Chief Coordinator (or, in his absence, by the Head Problem Coordinator). Observers attending coordination may not speak during the coordination session.
      The official scores are decided by the Coordinators. The Leader and the Head Problem Coordinator shall agree on the score for each problem for each Studnet Contestant. This score shall be recorded on an Official Score Sheet and signed by the Leader and the Head Problem Coordinator.
      A Leader may appeal an assigned score for a specific problem to the Chief Coordinator for that problem. If the two cannot agree, the appeal and the reason for rejecting the appeal will be forwarded to the Jury for a final decision.
      For each problem, the coordination of the solutions by Contestants from Canada shall be verified in the presence of the Leader from the country which submitted the problem. In the event that a problem was submitted by Canada, the coordination shall be verified in the presence of the Leader of the country present whose students achieved the maximum score in the 1994 International Mathematical Olympiad.
      The Jury shall:
        consider any dispute which may have arisen concerning the score allocated to a solution to a problem and determine the appropriate score,
        approve the scores for all Student Contestants,
        approve the award of prizes in accordance with 4.2 (d) above,
        consider and decide on any recommendations of subcommittees, and
        consider any matter raised concerning future International Mathematical Olympiads.
        The Jury may approve the awarding of a special prize at the recommendation of the Chief Coordinator for any student who has submitted a complete solution considered to be of outstanding merit.
    Date approved: 14 December 1994
