The International Mathematics Tournament of Towns is a mathematics problem solving competition in which towns throughout the world can participate on an equal basis.
Students participate in their own towns which involves minimal transport and administrative costs.
The southern hemisphere academic year coincides with this structure. The A level paper is more difficult, but offers more points. Students and their towns may participate in either stages or levels, or in all levels and stages. The Tournament is open to all high school students, with the highest age of students being about 17 years old. Students are awarded points for their best three questions in each paper, and their annual score is based on their best score in any of the four papers for the year.
