A

1. China
2. The government (China Computer Federation)

B

1. 10th grade although u can participate unofficially above 12yrs old(u cant go above NOI)
2. idk
3. i think its 5th grade for people starting now
4. 10th grade
5. 1(also u can only go above NOI once)

C

1. u are admitted to the top 2 universities in china if u get an official national gold
2. idk but once a teacher in tsinghua came to our school and told us that olympiad students are used(for want of a better expression) differently from other students

D

1. its pretty emphasized
2. individual accomplishment

Students are motivated by:

• Guaranteed admission to top universities
• National prestige and recognition
• Personal interest in problem solving
• career prospects

I'm away from OI now and didn't get very far so this could be wrong by a lot so correct me plz

UPD:Oh right students cant participate in grade 12

oh nice

A)

1. Australia,
2. Managed by the Australian Math Trust.

B)

1. Year 5 for informatics Olympiad,
2. 300 per year? maybe 200 — 1000.
3. Ages vary a lot to start, I started in year 7, making camp that year, while others start in years 8, 9, 10, or 11. Once or twice, somebody has made Australian camp in year 6, but that is very rare.
4. No minimum.
5. No maximum.

C)

1. Gold medal in the AIO is not highly significant for university admissions, though going to the Australian camp is enough to skip some first / second year computer science courses.
2. There is a special training camp, for a group of the top 30 students in Australia (as mentioned above), for 10 days, which leads to another group of 18 students, later in the year, with one final training camp for the IOI delegation and reserve.

D)

1. The Australian Camp is relatively competitive, but not nearly as competitive as those of camps such as China, US, Iran, or many other countries. Selection for the IOI team is very competitive, with many people spending a huge amount of time going for that. There are some tutoring centers teaching informatics, but generally people can get into camp with < 1 year of practice, making it not nearly as competitive as many other countries
2. International Olympiad in Informatics Success is regarded as a high personal achievement, as well as a high national achievement, with even a dinner with the prime minister (I believe).
3. I think the main motivation of most people at camp is because they do informatics for fun. Most people who get into the selection camp are aiming for IOI, which does lead to career positions. I happen to know one person who is motivated to do informatics as they want a pet seal. But overall, I think the motivation is mainly just personal interest.

I will answer mainly for informatics, other subjects (math, phys, chem, bio) follow a similar structure.

A1 Thailand

A2 Government-managed. Rounds up to national (e.g., Thailand OI) is managed by POSN (The Promotion of Academic Olympiad and Development of Science Education Foundation under the patronage of Her Royal Highness Princess Galyani Vadhana Krom Luang Naradhiwas Rajanagarindra). Training camp managed by IPST (Institute for the Promotion of Teaching Science and Technology).

B1 Grade 7 for informatics and math, Grade 9 for physics, chemistry, biology (for Bangkok POSN centers only. I believe it’s similar in other regions)

B2 About 10 centers, each with some hundreds (100 to 2000 idk depending on center) contestants. The number reduced recently due to the introduction of a preliminary requirement. Note that the first round is a paper-based math/code exam.

B3 idk. I did it since Grade 7 (but for math). I think people become more aware in high school (Grade 10).

B4 Grade 8 ig (first round in Grade 7 + 1 year of selection)

B5 three times.

C1 There are portfolio-based admissions, and Olympiads are heavily weighted. I’d say that if you apply to the subject of your Olympiad, and you won gold in national round, you have a very very high chance of admission. The chance is decent even with lower medals or if you did not have the Olympiad in that exact subject.

C2 National representatives(e.g., IOI contestants) may take a full ride to any uni overseas up to doctorate under bond conditions of working for government the same number of years of your study. Training camp participants are also eligible if the representatives refused their scholarship.

D1 There are many tutoring courses for early stages. There’s less for high levels (national level and above).

D2 I think it’s perceived as a national success thing too.

D3 Probably portfolio-based admissions. In higher levels, it might be more interest-driven.

Part A:

1. Vietnam

2. The government

Part B: https://codeforces.me/blog/entry/44575?#comment-291148

The only change is that TST is having 3 problems and a total score of 300 points for each day, so APIO score (out of 300) and TST (out of 600) are added together (900 points maximum) to select the IOI team.

There're no age restrictions on the IOI team (aside from being a high schooler), many did it while only being in 10th grade, so a maximum of 3 times.

Usually 600-700 students are selected for round 1 of our national olympiad, through provincial or school selection tests.

Part D is simmilar to the above.

We have no proper Informatics Olympiad, so for the informatics specific questions, I will refer to BwInf (National Informatics competition, is a documentation-based homework-copmpetition) which gets closest to this and is the contest where people for IOI-qualification-rounds are selected A) 1. Germany 2. Olympiads are organized by government sponsored organisations

B) 1. from 1st grade, for younger students there may be less rounds (so no national round for example) 2. 1500-2000 students 3. different from student to student and olympiad to olympiad. For example MO is introduced quite early with a competition for 3rd-graders, but I believe people start sweating for it in 8th grade. For informatics I dont think there are many people actively preparing for it. 4. afaik there ir no explicit limit, but it's really hard at younger age. This year, everyone participating in IOI-qualification rounds was in 10th grade at least. 5. afaik there is no explicit limit.

C) 1. not 100% sure. Afaik most universities have no entrance exam, you just submit your resume. For that, having won a medal definetly helps a lot. 2. IOI-particiapants and national winners at BwInf get into German Academic Scholarship Foundation without further selection process. Some universities offer scholarships to students that have reached a specific level.

D) 1. For everyone in the qualification process (top 60) there are lectures and practice contests for preparation. Also afaik there is a big preparation program for girls going on. As already mentioned there is like no national informatics olympiad, instead there is BwInf which is fun too, but not cp. There are also two easier competitions for younger students (One of them is held in Blockly, a language similiar to Scratch and the other one rarely ever forces you to code). IOI-selection is not competitive imo, at least when compared to other countries of similiar population. 2. If you win a medal at IOI or IMO or you win BwInf, there may be one or two articles in regional newspapers, but besides that nobody cares really I believe. 3. fun, curiosity and boredom ig.

A)
1. India
2. Managed by the Indian Association for Research in Computing Science (iarcs)

B)
1. any grade (I gave in 5th)
2. 2 exams in stage 1 in which you can qualify if you score good in either, one exam (ZIO), had 421 participants and the other, (ZCO), had 394.
3. usually 9-10th imo
4. no restriction afaik
5. no restriction

C)
1. Yes, many colleges such as IIIT Hyderabad, IIIT Delhi, IIT Kanpur, IIT Gandhinagar, and CMI favor people who score well.
2. idk

D)
1. mid, though recently more attention is being given to cp
2. also mid, ioi results gave last year in the newspaper tho
3. no idea, a bit of career prospects like college selection and fun ig.

A

1. United States

2. Managed by Brian Dean at Clemson

B

1. None

2. 7770 pre-college students (not all from USA)

3. i assume most people start in middle school

4. None

5. None, but historical max is 4

C

1. Platinum/camp/IOI help with college admissions, but are not guaranteed

2. idk

D

1. Very competitive

2. Mostly individual

3. College and career opportunities

A

1. India.

2. Hybrid Structure (IARCS)

B

1. Students in all grades are eligible.

2. 600-700 in total.

3. 11th grade.

4. There is no such lowest grade.

5. As many times as they want.

C

1. I am only aware of one top university which offers direct admission to national olympiad medalists and it is not even in top 10. Some universities in top 5 give advantage to olympiad medalists but it is not direct admission, you have to fight with other medalists to get in.

2. None, as far as I know.

D

1. There are basically no preparatory courses, even if there are, they are so bad that you are better off preparing on your own. Olympiads are not emphasized at all, Mostly students are encouraged to prepare for entrance exams for top universities. My guess is that 1 in 10000 students even know about the existence of IOI.

2. Somewhere in between.

3. Love for problem-solving and career prospects.

A. General Information 1. Uzbekistan 2. The government (Ministry of preschool and school education of the Republic of Uzbekistan)

B. Participation Framework

1. 9th grade, however there are exceptions for talented 8th graders
2. More than 2000
3. Usually 6 or 7th grade
4. Historically 8th grade
5. I think there is no limit

C. Incentives and Support

1. Yes
2. Usually, they are given scholarships.

D. Cultural and Educational Significance

1. We have our own alternative of codeforces (Hi robocontest.uz!). Top competitors are often invited to free intensive courses and camps.
2. It is regarded as high personal achievement with a lot of support from public and the government.
3. For many it is the prizes (lower stages also have money prizes), for others it is academic recognition

If any of my fellow Uzbek programmers have more info, feel free to make an addition.

I am talking specifically about Informatics Olympiads, the system varies a lot based on the subject.

A)

1. Croatia

2. Managed by Croatian Computer Science Association (HSIN)

B)

1. 9th grade for Croatian Olympiad (COI), 5th-8th grade for Croatian Junior Olympiad.

2. ~300 participants on the first stage. After a lot of competing 20-25 people qualify to Croatian Olympiad.

3. It varies a lot, but most people start from 5th/6th grade.

4. 9th grade for International Olympiads, 5th-8th grade for International Junior Olympiads.

5. No limit.

C)

1. You still have to do National exams, but you just have to pass, grade/points don't matter.

2. Some scholarships account Olympiad results, also usually after they finish high school, people mentor younger generations to pass the knowledge (usually paid, but sometimes volunteering) and are creating problems for all the competitions.

D)

1. A lot of individual preparation is required. In the "best" high school of the country there exists a weekly optional competitive programming class where former contestants teach. Also there is a summer and winter camp (national level wide) that lasts ~7 days. Students are also always doing something because of COCI (Croatian Open Competition in Informatics) being every 3/4 weeks (one way to reach the National Olympiad)

2. Usually the news reporters make a small part in the news about it, but it's mostly individual accomplishment.

3. It's hard to generalize motivation, but I think it's mostly people having fun solving problems + future career opportunities. Also if one wants to go to an international university, the Olympiad result doesn't hurt (usually for admission to national universities it's unnecessary)

Everything here is concerning the Egyptian Olympiad in Informatics (EOI).

A:

1. Egypt

2. A private organization governs the EOI, but the government sponsors (or used to sponsor) the EOI.

B:

1. There is no minimum. People as young as 6th grade have participated.

2. The online stage is usually around 100 to 200 participants.

3. Typically, people hear about it around the high school years (grade 8+).

4. There is no limit.

5. There is no limit.

C:

1. The only university that I know of which gives scholarships to competitive programmers is the Arab Academy for Science and Technology. The top universities in Egypt do not offer such scholarships.

2. There used to be support programs in the past. Egyptian IOI medalists would win monetary prizes, or new laptops. This is no longer the case.

D:

1. Very few students have heard about the EOI. It is not competitive.

2. It is seen as a national achievement. The Minister of Education and other high-ranking Egyptian officials attend the final ceremony.

3. The main motivation is to aid in admission to foreign universities and scholarships. Foreign universities are, on average, stronger than Egyptian universities, and provide better opportunities for students.(At least, for the people who attempt to qualify to the IOI. Many students participate to have fun, or because competitive programming can look good on a résumé.)

A)

1. Russia

2. Main olympiad is managed by government, there are some other olympiads (usually managed by universities)

B)

1. Technically no, the final and semifinal rounds (there are 4 rounds) are from the 9th (out of 11) grade, but you can participate for a higher grade officially

2. I found statistics only for 4 years ago, it was 209458 people with non-zero result among all grades, 49097 of participating for 9-11 grades (but the first round is held online)

3. I guess it depends on the circumstances. For a student in a standard school probably it will be 5-7 grade firstly hears about it, 9-10 grade starts thinking about it if plans to go to university. Advanced schools usually starts from the 5th grade, so it will be 5-7th grade

4. Technically no

5. Technically no

C)

1. You gain admission without exams from the diploma of the final round of national olympiad (225 people previous year) to study for free. Also university can give the same right for medalists of other olympiads, but they can limit with requiring to get at least X points on national exam (usually 70-90 out of 100)

2. Your region can give you money (it depends, some even pay a bit for the second round), it's often easier to get to the internship with a final round's diploma, some companies give scholarships for the first year in university, universities also have scholarships

D)

1. Yes, there are some free courses from tech companies, a governmental center with onsite educational programs for different classes for free, some regions prepare people from them, there are a lot of private courses and camps

2. More like a national achievement

3. Getting to a top university (it's almost impossible to get for free without olympiads), but from some point interest is more important cause people already got an admission

A. General Information

Country name: Bangladesh

Organizational structure: The Olympiad is organized by the Bangladesh Olympiad in Informatics Committee (BIOC), a national committee supported by educators and volunteers.

B. Participation Framework

Minimum grade eligible: Students from Grade 6 to Grade 12 can participate. In Bangladesh, Grade 6–10 is high school and Grade 11–12 is college. Students can participate until age 18 and before finishing the final board exam after Grade 12.

Average number of participants in the first stage: About 200 students usually participate in the online preliminary round.

Typical starting point for preparation: Most students become familiar with Olympiads during high school, usually around Grade 8–10.

Lowest grade for national team: Any eligible student from Grade 6–12 can be selected if they perform well.

Maximum number of selections: There is no fixed limit, but a student can only be selected while they are under 18 and still in school or college.

C. Incentives and Support

University admission privileges: Olympiad medals do not officially provide direct admission to top universities. Students still need to pass competitive university admission exams.

Long-term support programs: Selected students receive training camps and mentoring before international contests, but long-term support programs are limited.

D. Cultural and Educational Significance

Competitiveness: Olympiads are not very popular yet. Many talented students focus more on academic studies and university admission exams.

Public and institutional perception: Olympiad success is respected in the programming community but is not widely recognized nationally compared to academic exam success.

Student motivation: Students mainly participate because of interest in programming, curiosity, international competition experience, and personal achievement.

Selection process: An online preliminary round with about 200 participants is held first. Around 50 students are selected for the offline national round, which lasts about 1.5 days. The top 15 students are selected for training camps. After that, students participate in regional contests such as the Asia-Pacific Informatics Olympiad, and the top 4 highest scorers are selected for the International Olympiad in Informatics team.

Country: Bangladesh

• Olympiad system: Mainly organized by Bangladesh Mathematical Olympiad Committee (BdMO) and Bangladesh Olympiad associations, with support from universities and sponsors. Informatics Olympiad is smaller compared to math but steadily growing.

• Participation: Students usually start from Grade 6–7. Regional rounds lead to national finals, and top students are selected for international contests.

• Incentives: Winners receive recognition, medals, and sometimes scholarships. However, university admission privileges are limited compared to countries like Russia or Iran.

• Cultural significance: Olympiads are prestigious among schools and students, but they are not yet a mainstream national achievement.

Cool editorial!)

A The Kingdom of Saudi Arabia (KSA) Mawhiba — NSMO (National Science & Mathematics Olympiad) — اولمبياد العلوم والرياضيات نسمو

B Students, as young as grade 7 can participate up to grade 11, participating in grades >11 requires with exception such that the student must already be qualified for Mawhiba's Program for International Olympiads (برنامج موهبة للالومبيادات الدولية)

The number of students in informatics is 11,000. |

I'm unsure of the minimum age for participation in the national team, but I believe it is 15.

C Gold medalists often get national benefits, money from the prince (MBS, formally known as Muhammad Bin Salman), direct admission to top tier colleges, alongside several other benefits.

D The saudi olympiad is unfortunately underwhelming, Out of 11,000 students, 2% of them are your competition if you are already comfortable with CodeForces. Its cultural significance is very high, as in gulf culture, honor and education are highly valued.

Student Motivation: The national olympiad offers an experience like never before, you get to travel a ton (and best part, skip school! which is my favorite part), you get to know several people who are your main source of motivation, national rewards, social (& familial) rewards.

Another(and more complete)reply for China's OI.

A

1. China
2. CCF(China Computer Federation).

In fact, in the about-us page, it is said that CCF is not a goverment's organization. But it has connections with the party, as https://codeforces.me/blog/entry/150570?#comment-1343488 mentioned.

B

1. The mainline contests (covering CSP-J/S, NOIP, province team selection, NOI, CTT, CTS, IOI) is only available for those who aged 12 or more, and only students whose grade are 11 or lower can participate in province team selection and later contests, only 10th and 11th graders can participate officially in NOI or later contests(junior high students can take part in NOI unofficially); but there're contests like GESP(also held by CCF) and regional contests targeted at primary school students(or even children in kindergartens for some families).
2. There're no(at least not public) datas for the first round in CSP-J/S. For the second round, there're about 40k participants in J and about 30k in S. Only participating in S can a participant get the access to the later contests.
3. This depends on regions. In strong provinces, pupils are normally start at grade 3~5 or even earlier(like I mentioned above, even kindergarten); for the most provinces not that strong, the starting year is often grade 6 or 7, and students only want an award in NOIP can be later in grade 8~10.
4. In the season that you're in grade 10, normally around 16 years old. But for those who are in the national team, the season will last over a year, and they will be grade 11 when they go to IOI.
5. Two times, the year in the last question I mentioned, and the year after that year.

C

1. Recent years, top 50 official participants in NOI(also gold medalists) will receive direct university admission to Tsinghua University or Peking University without taking exams. Silver medalists can get little bonus when going to these two universities. Bronze and first prize in NOIP are nearly the same, and some good universities may also give you bonus. For detailed informations you can see this post
2. idk.

D

1. Usually, you will be socially prestigious only if you achieve at least first prize in NOIP(silver for some schools). Or for some conditions you'll even be a joke. Almost all students that want to get silver or more need to abandon massive school courses to train. After COVID-19, there are lots of camps for OI, and many high schools have their own school teams.

In fact, in some regions(like many cities in Shandong) in China, anything that is benificial for entering a university is nearly deified, and anything won't get in the way of them.

1. If you're successful, your school will be proud of you and put you in its advertisement. Beside this, it's all personal success. No one cares OI except schools, participants and their parents(the last also only care about the prize, most of them don't even know what does OI do).
2. For different students, it's different. Mainly these:

• Admission to top universities
• Escape from boring and tiring school courses
• Personal interest in problem solving

Just like a gold medalist said, you can't success when only interest motivates you. The admissions to top universities is nearly necessary. What's more, without this, many parents and schools will stop students from learning OI, because they'll regard them as useless.
