Regulations for International Competitions
International Mathematical Olympiad
The International Mathematical Olympiad (IMO) is the World Championship Mathematics Competition
for High School students and is held annually in a different country. The first IMO was held in
1959 in Romania, with 7 countries participating. It has gradually expanded to over 100 countries
from 5 continents. The problems in the IMO comes from topics in Number Theory, Algebra,
Combinatorics and Geometry. Though the problems are based on high school material, solving them
requires exceptional mathematical ability and thinking. Participation in the IMO is by invitation
only. Each invited country is entitled to send a team consisting of up to six contestants, a Leader
and a Deputy Leader. The contestants individually solve same six problems on two consecutive days.
In each day they are given three problems to solve within a time limit of four and half hours. For

Selection Process of the Sri Lankan Team to the International Mathematical Olympiad
- A team at most of six students will be selected to compete in the annual International
Mathematical Olympiad through a series of selection tests known as IMO Team Selection Tests
- Participation in IMO team selection tests is by invitation only. The first 10-15 students of
Sri Lankan Mathematics Challenge Competition (SLMCC) who has demonstrated strong mathematical
abilities through their SLMCC performance will be invited to participate in IMO TSTs. Number of
participants in IMO TSTs can vary from year to year based on the way students have performed in
- The age and student status criteria given in the IMO annual regulations to determine the
eligibility to participate is the following. Contestants must have been born less than twenty
years before 1st of July in the year of participation at the IMO. Contestants must have been
normally enrolled in fulltime primary or secondary education on or after 1st of December in
the year prior to the IMO.
- In order to get selected in to the Sri Lankan IMO team the student must be a citizen of Sri
Lanka with at least two years of secondary school education in Sri Lanka.
- In case of a former Sri Lankan IMO participant who has participated in the IMO three times
an achievement of Silver or Gold in one of the previous participations is required to
participate for the fourth time.
- In case of a former Sri Lankan IMO participant who has participated in the IMO two times
without winning a medal an achievement of an honourable mention in one of the previous
participations is required to participate for the third time.
- Sri Lanka Olympiad Mathematics Foundation reserves the right to withdraw any student who
does not show enough commitment towards IMO or who does not show a satisfactory progress in
achieving the expected problem solving skill level at IMO. The criteria to determine the
commitment and progress will be announced with the invitation to the IMO TSTs.
Asian Pacific Mathematics Olympiad
The Asian Pacific Mathematics Olympiad (APMO) is a regional mathematics competition for countries in Asia
and Pacific region. It started in 1989 and in 2017 the number of participating countries was 39. The APMO
contest consists of one four-hour paper consisting of five questions of varying difficulty and is conducted
by a representative in each participating country. The problems are prepared by a senior coordinating
country with the help of an assistant coordinating country and a moderating country. Sri Lanka Olympiad
Mathematics Foundation is the representative of APMO in Sri Lanka. In each year the APMO is held in the
afternoon of the second Monday of March for participating countries in the North and South Americas, and
in the morning of the second Tuesday of March for participating countries on the Western Pacific and in
Asia. For more information visit: http://www.ommenlinea.org/apmo/
Eligibility criteria to participate in the Asian Pacific Mathematics Olympiad representing Sri Lanka
- In each year SLOMF invites 10-20 students to participate in the Asian Pacific Mathematics Olympiad
based on their performances in the Sri Lankan Mathematics Challenge Competition of the year prior
to the APMO.
- Contestants should not have formally enrolled at a university (or equivalent post-secondary
institution) and they must be younger than 20 years of age on the 1st July of the year of the
- Results of a maximum of 10 students (the maximum possible number of official contestants per
country) will be sent to the senior coordinating country to determine the awards. The priority
will be given to the contestants who solve at least one problem completely.
- Sri Lanka Olympiad Mathematics Foundation reserves the right to revoke participation of any
invited student who does not show enough commitment towards APMO or who does not show a
satisfactory progress in achieving the expected problem solving skill level at APMO. The
criteria to determine the commitment and progress will be announced with the invitation.
International Mathematics Competition (IMC)
Please see the IMC 2016 Brochure. A team for IMC category III is selected by inviting top 30
performers at SLMC who satisfy the age criteria stipulated by the competition organizers for
a selection test.
