Any team that agrees to abide by these rules will be admitted during any semester, before the first contest, upon application to join the league.

Division structure and problem difficulty

Please click here to see 2 years of free contest samples.

There are four divisions of the NYCIML: the Soph-Frosh, Junior, Senior A and Senior B divisions. There will be five Senior A and Senior B meets, three Junior meets and three Soph-Frosh meets each semester.

Senior division problems may involve any topic up to precalculus mathematics. Questions in the Senior B division will be less difficult than those in the Senior A division. No school may compete in both Senior divisions in the same semester.

Junior division problems will involve no mathematics beyond that taught in the Integrated Algebra, Integrated Geometry, and/or Algebra 2 and Trigonometry New York State Regents syllabus.

Soph-Frosh division problems will involve no mathematics beyond that taught in the Integrated Algebra, and/or Geometry New York State Regents syllabus.

Note that the contests in all divisions will require problem-solving skills and creativity beyond what is typically required to answer textbook-style problems.

Meet structure, tie-breaking and dropped problems

Each meet will consist of six problems, given in three sets of two problems each. There will be no tie-breaking contests. If a problem must be dropped for any reason (as decided by NYCIML) then a substitute MAY be proposed on a later contest. If this is not feasible, no replacement will be made, and no credit will be given for ANY answer to the discarded problem.

Team composition and number of teams per school

A team will consist of five active students and each school has a maximum of four substitute students. Five active students for each team should be decided no later than the submission of the first contest score. Once the five active students are decided, they will be representing the team for the rest of the year and CANNOT BE CHANGED. You may submit substitutes’ scores for some contests and only that particular contest only if some of the five active members are absent. Substitutes’ scores can only be counted for the team’s score but not as an individual. Otherwise, only those five active members’ score will be accepted. Note that you SHOULD NOT submit more than five scores for each contest.

Eligibility of Students and Number of Awards

  • Any student enrolled in a member school is eligible to participate in any contest in the Senior divisions.
  • Students in their senior year enrolled in a member school that does not field a senior team may participate in any contest in the Junior division, as long as a majority of the members of the Junior team are in their Junior year of high school. Schools that field a senior team may not allow a student in his or her senior year to participate on a junior team. Any student not yet in his or her senior year may participate on a junior team.
  • Only students taking Integrated Algebra, Geometry and/or Algebra II/Trigonometry in the fall of the school year may participate in the Soph-Frosh division during both the fall and spring semesters.
  • A student may compete officially for at most one team each semester. Thus, a student who has competed as a member of one team may not also compete as a member of another team in the same semester. However, a student who has officially competed for a team may be placed on a different team in a following semester.
  • A school may win awards in the Senior, Junior, and Soph-Frosh divisions, but no school may win more than one award in any one division, regardless of the number of teams entered by that school.
  • For any winning team that has more than 7 members competing in a given semester, only the
    seven top members will be awarded.
  • Specialized high schools are awarded separately from regular schools (Special Senior A, Special Senior B, Special Junior, and Special Soph-Frosh). For any specialized high school team to be awarded in these divisions, the team must score higher than the highest score from a regular school team in the respective division. (e.g. if regular team A has the highest score in Junior division with a semester score of 60 and specialized team A, B, and C has semester scores of 56, 70, and 75, respectively, then only specialized teams B and C are awarded in the Specialized Junior division)

Contest Procedures

  1. PLACE OF ADMINISTRATION: All contests are administered at the team’s school on the announced day of the contest.
  2. PROCTORING: Each contest must be actively proctored at all times by a math teacher who must sign the contest reports to be forwarded to the NYCIML secretary. Neither the proctor, nor anyone else, may interpret or explain any problem to any student during the competition.
  3. CONTESTANT SUBSTITUTIONS: Students officially designated as competing shall be the only ones whose scores are counted towards the team score. These designations must be made PRIOR to the distribution of each meet. These five students are the only ones from the team who have their answers recorded on the official results sheet for that particular meet. These five students must be told BEFORE each meet that their scores will count.
    But, again, we would like to encourage all students of the school’s math team/club; coaches are allowed to have unregistered students to take the contest with the registered teams. Most coaches choose to have the registered students sit in one section of the room, so that it is easier to retrieve their answers to the contest questions.
  4. MATERIALS ALLOWED: Only plain paper, to be supplied by the school, and pencil or pen, may be used by the contestants. No graph paper, compasses, straight edges, rulers, mathematical tables, calculators, or other devices are allowed.
  5. STARTING TIME: Meets may be held at any time during the scheduled day.
  6. CONTEST DATES: All meets must be held on the scheduled dates, unless an entire meet is rescheduled or unless specific exemption is made by the Executive Board due to extraordinary circumstances. If your team needs a meet rescheduled, please don’t hesitate to contact us at Contest dates can be found on the NYCIML website [link here].
  7. START OF CONTEST: First, the proctor distributes the first pair of problems, face down, and each contestant writes his/her name and the date on the top of the sheet. Each contestant must also write the numbers of the two problems being attempted. Answers submitted must appear next to or near the appropriate problem number. Answers written next to the incorrect number or elsewhere receive no credit. The proctor will then ask the students to turn the paper face-up and the proctor will read the two questions aloud one time each, in succession. Students cannot be holding any writing utensils while the proctor is reading the questions. Any student caught with it is automatically disqualified. The proctor will then signal the start of the contest and he/she will record the time. The same procedures shall be followed for succeeding problems. The proctor shall not explain any question to any contestant during the competition.
  8. WARNINGS: Warnings that “five minutes remain”, that “one minute remains”, and that “fifteen seconds remain” should be made to all contestants at the appropriate times. No other warnings or announcements (relative to the contest) should be made to any contestant under any circumstances.
  9. MARKING THE ANSWERS: Any student who continues to write after time has been called must have both his/her answers disqualified. The answer papers are to be collected, immediately, by the proctor or by a student who will then give them to a proctor. The proctor will then, privately, look at the official answers, read them aloud, and write them on the board. The proctor will then mark each paper and write the scored results for each officially competing team member on the score report form and (if so desired) on the board. Any disagreement as to scoring should be resolved immediately by the proctor. Each team captain is responsible for the accuracy of the written report of his/her team. Answers mathematically exactly equivalent to the official answer shall be given credit, except when a specific answer form has been asked for. In that case, that answer form must have been adhered to for the student to receive credit. Answers incomplete in any way receive no credit. No partial credit is allowed. An appealed answer should be scored as an “A” on the report form submitted to the NYCIML. The word “compute will always call for an answer in the simplest form. Thus final answers like 6/4, 5 + 2, 2^5, √25 and 2 sin30°, for example, would not be satisfactory. In cases where there is a question as to what is “most simplified”, alternate answers may be accepted (example: 3/2 and 1.5 are both acceptable). Answers containing radicals should be in the “simplest” radical form. (No radicands with perfect square factors, no fractional radicands, no irrational denominators)
  10. RESULTS: Results will be submitted online on our website at As of September 2014, we no longer require electronic faxing. Email us at if you run into any problems.
  11. APPEALS PROCEDURES: Appeals may be awarded only on the basis of a disallowed exactly equivalent answer or on the basis of an alternative interpretation of the problem and a correct answer to that interpretation. Alternative interpretations should be mailed to the secretary with written substantiation as the acceptability of the interpretation. If there is no answer possible for a question, only the answer “no answer possible”, or its equivalent, will be accepted, even though the official answer lists a possible answer. Appeals, which cannot be readily handled by the executive board, will be forwarded to an appeals judge for review. The NYCIML secretary will automatically adjust scores of all students submitting the same answer as an answer winning an appeal or improperly awarded credit, such changes to be indicated on the official contest reports distributed by the secretary.

Fee Waiver for New Schools

A school will be considered a new school if it has not competed in the NYCIML within five years of the current competing year. Any new school that decides to join the NYCIML is eligible for fee waivers for any division. In order to redeem this waiver, please email us at
