The of cial working language of the IOI is English.

S1.6
In the scope of the IOI the concept Informatics means the domain that is also known as computerscience, computing science and information technology, but not the domain computer engineering.
E1.2
All statements which are placed in the
Statutes, the Explications, Appendices and the Code of
Conduct, as well as rules and procedures drawn up by
the Host Country for IOI’n, are meant to regulate theformal communication between the participants. Where
the Regulations do not give explicit guidance, theparticipants are asked to act in the general spirit of theRegulations.
N1.1
The original idea of initiating the IOI was proposed to the 24th general conference of UNESCO by the Bulgarian delegate
Professor Blagovest Sendov (1932–2020) in October 1987. This plan was included into the fifth main program of UNESCO for thebiennium 1988–1989. In May 1989, UNESCO initiated and sponsored the first IOI, which was held in Pravetz, Bulgaria.
N1.2.1The IOI Regulations have two purposes: a formal description of the IOI, and information about the IOI. The Regulations
are also meant to be more than just procedures. The other purpose is that the IOI Regulations give:
New participating and observing Countries a quick overall idea of what the IOI is and how it works;
Information about what steps should be made to become a Host and to organise an IOI in a certain year;
Historical information.

S2.1
For the IOI, a Country is a state that has an of cially recognised relationship with the United Nations,
UNESCO, or which has already taken part in one or more past IOIs.
S2.2
The organisation of the IOI in year n is the responsibility of the Host Country for IOI’n. A Host Country
consists of the responsible Ministry(ies), Institution(s), and/or Corporation(s) in that Country.
S2.3
Each participating Country is represented by a National Delegation; all members of a National Delegation
represent one Country. A National Delegation is headed by a Delegation Leader, includes a team of one to fourContestants and, if there is more than one Contestant, may include a Deputy Leader.
S2.4
The Deputy Leader can act as a replacement for the Delegation Leader in all situations and may assist
their Delegation Leader in all their duties.
S2.5

A Contestant is a student who
1. for the majority of the period 1 September to 31 December in the year before IOI’n:
was enrolled in a school at a level of secondary education or lower, in the Country they
are representing; andwas not enrolled in a degree programme at a tertiary education institution with a half-timeor greater load.
Exceptions to this may be requested through the IC. Students who are studying abroad may
instead represent the Country of their nationality.
2. is not older than twenty years on the 1st of July of the year of IOI’n.

E2.2
A Host Country can have the status of Past
Host, Present Host, Future Host or Host Candidate.
E2.3.1
If the Host Country for IOI’n wants to invitedelegations with more or less than four Contestants, it
must be approved at a GA meeting during IOI’n-1.
E2.3.2
The Delegation Leader and / or the Deputy
Leader must have an appropriate scientific background.
They must be qualified to represent their Contestants intechnical and task issues that arise during thecompetition and GA meetings.
E2.5
Secondary education ends with some form ofschool-leaving examination. Tertiary education, such asoffered by Technicons and Universities, may immediately
follow Secondary education, but may also be precededby some form of preparatory pre-tertiary education.
Such pre-tertiary education is not regarded as Secondary
education.
N2

Homeschooling is equivalent to Secondary school
enrolment, for as long as the student has not received asecondary school diploma (or equivalent) and is working
toward such a credential.
A2.5
Students who are to be considered for
representing their delegations at an IOI must, in addition
to meeting the eligibility requirements set forth in S2.5,
have participated in a selection procedure that:••

Is based on ability and includes a test of the students’programming and problem solving ability;
Is open to all eligible students in their delegation’sCountry, although restrictions may be placed onwhere, when and how students can enter theprocedure, and a student’s nationality can be limited
to that of the relevant Country.

All persons mentioned in Statutes S2.3–S2.9 are referred to in this document as Participants.

N2.2
It is firmly recommended that Countries reasonably circulate the yearly issues of the IOI among each other. To spread theaverage costs for travel it is also recommended that Host Countries are staggered geographically.
N2.5.1
It is firmly recommended that Contestants should have participated in a local, regional or national informatics
competition in their Country as a pre-selection for the IOI, and that they belong to the winners of that competition.

fi

N2.5.2
The age limit for contestants may also be defined as: Every contestant at IOI’n (held in year n) must have been born on
or after 1st July, in the year n − 20.

Participants
S2.6

2.6 - 2.9

An Invited Observer is a representative of:• A new Country that has not previously participated at the IOI and is bringing no contestants (×1);• Future Host of IOI’n+1 (×2) and IOI’n+2 (×1).
A Country can only have Invited Observer status, as a new Country, for one year. Exceptions may be consideredby the IC.
S2.7

The other invited participants, whose cost is covered by a Host Country:• IC, ISC and ITC Members;• The organiser of the IOI conference, if it is scheduled;• At most 3 Invited Guests proposed by the IC in co-operation with the Host Country.
S2.8
•
•
•
•

Additional participants, whose cost is not expected to be covered by a Host Country:

External Contestant: Any contestant who is an unclassi ed participant in the contest;
Adjunct to the Team: A person who has a duty adjunct to the team (e.g. nurse, chaperon or translator);
Adjunct to the IC / ISC / ITC / OIOI: Invited by the IC / ISC / ITC / OIOI based on need;
Guests: Participants who are not classified as Invited Guests, have no duty, and participate on thebasis of entertainment / sightseeing (e.g. family members).

S2.9

The Host Country may invite additional participants, such as:• Local Committee Members;• Press;• Guides.
E2.6.1Each Country has the right to be invited once
as an Invited Observer. Exceptional invitations may also
be considered, as described in S2.6.
E2.6.2
An upper limit on the number of new
countries must be set by the IC, with agreement by the
Host Countries for IOI’n+1 and IOI’n+2, during IOI’n.
E2.8
A Country or Committee wishing to send suchparticipants must agree this with the Host Country prior
to the IOI, in a time period to be determined by the host.
N2.6.1The Invited Observer status (for new Countries) is introduced as a possibility to see the IOI in practice before
participating in the IOI. But the more functional reason is that by introducing such Invited Observer status, the number ofParticipating Countries is regulated. This has the advantage that the IOI and the Future Hosts are not surprised by an unforeseenamount of complete Delegations in the next year(s).

fi

N2.6.2
If a Country wishes to attend IOI as an Invited Observer, they should contact the Secretary of the IOI for information on
how to apply. A typical application would include information about programmes that are already established within the Country.
The IC is responsible for deciding whether to approve such applications.

An of cial representative of a Country that is capable and willing to organise an IOI in a particular
year, must submit a Letter of Intent to the Secretary. The Secretary will acknowledge the Letter of Intent andsupply rules applicable to the situation. The Country becomes a Potential Host.
S4.2
The IC performs a selection procedure and nominates a single candidate from the Potential Hosts for
hosting the IOI in a speci c year. This decision must be rati ed by the GA. After rati cation, the Secretary will
issue a formal written Invitation at which point the Country becomes the Candidate Host for year x.
S4.3
A Candidate Host receives the status of Future Host when the Invitation is accepted by the nationalorganisation(s) involved, and con rmed in writing to the Secretary. The IC informs the GA at the rst GA
meeting after this con rmation.
S4.4

The Future Host becomes the Present Host in the year in which it hosts the IOI.

E4.1.1Countries may become Potential Hosts forany year up to IOI’n+7.
E4.1.2
A Country may submit more than one letter ofintent, each being for a specific year.
E4.1.3More than one country may submit a letter ofintent for a specific year.

Hosts including, but not limited to, information on:
•
•
•
•
•

Proposed venues (competition and accommodation);
Availability of hardware resources;
Human resources (including HSC);
A rough draft budget;
Fund raising plans.

E4.2.1
The intent of IC is that the selection procedure
for IOI’n will take place during IOI’n-4, and the status
of Candidate Host will be conferred shortly after. The
selection will not take place any earlier than IOI’n-5.

the ISC’s decision with a 2/3 majority vote.
S6.14
It is possible that a Country cannot participate in IOI’n due to a diplomatic issue with the Host
Country, where the Host of IOI’n has advised the IC that it is highly unlikely that the Country will be granted
permission to enter the Host Country. In such a case the IC may, at its discretion, allow the Country toparticipate from a remote location. This Country must apply to the IC for remote participation no later than
IOI’n-1.
E6.11
If, before the end of the GA meeting in which
the awards are confirmed, it is discovered that one ormore Contestants fails to meet the eligibility criteria of
S2.5, then the number of contestants used to computeaward boundaries will be reduced accordingly.
E6.12
If a contestant is disqualified, they will still becounted for the purpose of computing boundaries forawards as described by S6.11.
E6.14
The award boundaries, as described by S6.11,
are determined using only those Contestants who arecompeting on-site in the Host Country. The official
archives and website of the IOI will also include theremote Competitors, with awards based on theboundaries that were determined on-site.

A6.14.1 The IC, in consultation with the ISC and ITC,
will choose a representative to oversee the remotecompetition.
A6.14.2 The remote competition will take place as
close as possible to the same time as the IOI. Some
small delay is acceptable, but only if the remote
Competitors can be quarantined.
A6.14.3 All remaining details regarding the remotecompetition will be determined by the IC, incollaboration with the ISC and ITC.

N6.11.1

Contestants and their Delegation Leader should be told their points, so that appropriate appeals can be made (see S6.10).

N6.11.2

The HSC’s proposal and GA’s confirmation can take place at any GA meeting (S3.2) before the IOI Awards Ceremony.

N6.11.3

Revisions to the Regulations, adopted during IOI’n, become binding at the end of IOI’n.

S7.4
Regulation changes may be implemented more quickly, without the full procedure of S7.3, provided
there is IC approval. The GA requires at least one months noti cation. The GA must ratify these changes in the
rst GA meeting of IOI’n, and if rati ed then the changes become binding immediately after this vote.

E7.1
Proposals for Regulation changes, bymembers of GA, can be submitted to IC forconsideration. These should be submitted through theSecretary or the President of IOI. All proposals, whether
adopted or rejected, must be communicated to the GA.

A7.1
Proposals for Regulation changes submitted
between the IC meeting prior to IOI’n and the meeting
prior to IOI’n+1 will be discussed, at the latest, at the IC
