Official Rules

The Purple Comet! Math Meet is a free, annual, international, online, team, mathematics competition designed for middle and high school students that has been held every year since 2003.

How It Works

  • The Purple Comet! Math Meet is a team competition.
  • Each team is required to have an adult supervisor.
  • Supervisors must register at the contest website.
  • Supervisors may register teams for the competition during the team registration period which begins February 1 and continues through the end of the competition.
  • In the competition, middle school teams are given 60 minutes to work on 20 mathematics problems, and high school teams are given 90 minutes to work on 30 mathematics problems.
  • The team supervisor may select any period during the 232 hour competition window for the team to compete.
  • Supervisors of multiple teams may have all of their teams compete at the same time, or have some teams compete at one time and other teams compete at other times.
  • Any time during the competition window the team supervisor may optionally download and print copies of the competition problems so that the printed copies can be distributed to team members when it is time for them to begin the competition.
  • The team supervisor starts the team's competition by logging onto the contest website and starting the team clock.
  • The team logs into the contest website and sees a list of competition problems on the screen.
  • The team submits answers to the competition problems during the 60 minutes (middle school) or 90 minutes (high school) of the competition.
  • A few days after the competition ends, the competition results are posted on the contest website. Supervisors may then download participation certificates and award certificates from the contest website.

Rules For Supervisors

  • Any adult aged 21 years or older may serve as a team supervisor.
  • Each supervisor must register as a supervisor at the contest website.
  • Once registered, there is no need to register again; the contest website retains supervisor registrations from year to year.
  • One supervisor may supervisor as many teams as they like. For example, a teacher at a school could supervise many teams from that school.
  • A school may have more than one person working as a team supervisor, although it is recommended that these supervisors coordinate their activities to ensure that no student participates on two different middle school teams or two different high school teams.
  • Supervisors are often teachers at a school, but this is not required. Parents, relatives, family friends, or mathematics club advisors also work fine as supervisors.
  • Supervisors are responsible for ensuring that contest participants are following the rules of the competition. This includes reviewing the competition rules with the team members before the start of the competition.

Rules For Team Formation

  • The Purple Comet! Math Meet is a team competition. Students on the same team are encouraged to work together to solve contest problems.
  • The contest is designed for teams of students from anywhere in the world enrolled in middle school or high school (or local equivalent), or home-schooled students who are at a comparable level. Non-competitive teams are open to any participants regardless of grade or age.
  • A team may have as few as one student and as many as six students.
  • Teams may enter in one of eight categories:
    • Middle School Level for small school teams
    • Middle School Level for large school teams
    • Middle School Level for mixed school teams
    • Middle School Level for non-competitive teams
    • High School Level for small school teams
    • High School Level for large school teams
    • High School Level for mixed school teams
    • High School Level for non-competitive teams
  • Small school teams, large school teams, and mixed school teams are competitive, and team members must meet age, grade, and school size criteria. The contest results for the top teams in these categories are posted on the contest website, and special award certificates are provided to members of winning teams with other teams receiving participation certificates. Membership on non-competitive teams is not restricted in any way. Contest results for these teams are not posted, and team members receive participation certificates. The non-competitive categories are designed for teams that wish to participate in the Purple Comet! Math Meet but do not want their results compared to other teams.
  • All competitive middle school team members must be students who have not yet completed the eighth grade (or local equivalent), and who are under the age of 16 as of the date of the competition.
  • All competitive high school team members must be students who have not yet graduated from secondary school (or local equivalent), and who are under the age of 20 as of the date of the competition.
  • Competitive teams may register in the large school category, the small school category, or the mixed team category. All students from a large school team or a small school team must be enrolled as students in the same school. The school size should be determined from the size of the student population from which potential team members have been drawn. Some schools are spread out over a campus comprising several buildings. If a team could be comprised of students from across the entire campus, then the entire campus should be considered when calculating the school size. Mixed teams are designed for home schooled students, students who all attend the same regional mathematics club, or some other non-school organization. All the students from a single mixed team must have residences within 150 miles (240 kilometers) of each other.
  • High schools qualify as small if they have no more than 1200 students. Middle schools qualify as small if they have no more than 400 students.
  • No student may participate on more than one middle school team or one high school team, although a student eligible for the middle school level may compete both on one middle school team and on one high school team.
  • A school may enter as many teams as they like. Each team is required to have access to its own computer with an Internet connection. If two teams at the same school need to share a computer, then the two teams are required to compete at different times with one team completing the entire competition before the other team starts.
  • Team members need not all be from the same school. Mixed school teams are designed for teams made up of students who do not attend the same school such as home schooled students, members of an area mathematics club, or groups of friends.
  • Each team must have an adult supervisor (age 21 year or older) who is able to monitor the team to ensure that competition rules are being followed. An adult supervisor may supervise more than one team.
  • Teams may enter either as a middle school team or a high school team. The competition problems for middle school teams will be fewer in number and of a lower degree of difficulty than those for high school teams.

Rules For The Competition

  • Each team is given a team name at the time that the team supervisor registers the team. Team names may be edited if deemed inappropriate by the contest judges or if there are two teams with the same name.
  • The contest is conducted via Internet web form. Teams may fill in answers to the contest problems during the prescribed time for their team (60 minutes for middle school teams, 90 minutes for high school teams) following the start of their contest clock. At any time during the competition, contestants can click the SUBMIT button to submit their team's entry. Answers may be submitted multiple times by the same team, but for each problem only the last answer received before the contest ends will be accepted and graded. Partial submissions are accumulated. Consequently, if a team submits an answer to problem 1 and later wises to submit an answer to problem 2, there is no need to resubmit the answer to problem 1.
  • Contestants are allowed to work on the contest problems as a team. No help may be provided by persons not on their team.
  • Team members and team supervisors must not reveal or discuss contest problems with anyone other than their immediate team members until the contest officially ends at Thursday, April 27, 2017 at 04:00 PM UTC.
  • Team members and team supervisors must never post contest problems where they would be available to others before the contest officially ends at Thursday, April 27, 2017 at 04:00 PM UTC. In particular, it is against the contest rules for anyone to submit contest problems to a website whether or not the website encourages students to submit challenging mathematics problems.
  • All problems in the competition are designed so that they can be worked without the aid of calculating devices. On the other hand, participants are permitted to use calculators or computers, for example, to write a computer program in order solve or better understand a problem. Team members may also refer to books, computer programs, or other reference materials available to them locally as long as the students seek this material without aid from persons not on their team.
  • Participants may not use computers or any other communication devices to seek help with problem solutions from people or Internet resources outside of their own team members.
  • Ideally, if computers are made available for help with problem solutions, they should be different from the computer used to access the competition website, and should be physically disconnected from the Internet during the time when students are actively working on problem solutions. If this is not possible, then adult supervisors are asked to monitor participant use of computers carefully.
  • The decision of the competition judges is final.
  • The official time is the time as determined by the purplecomet.org server.

Other Rules

  • Any circumstances not covered by these rules may be decided at the discretion of the competition designers.
  • These rules may be amended from time to time without notice. The rules in effect at the start of the competition are the official rules of the competition.
  • The contest is free to all participants, although your gifts to help cover the expenses of running the event are encouraged. Learn how you can help.
