In addition to organizing the International History Bee and Bowl, International Academic Competitions organizes the International Science Bee, International Science Championships, and the International Environmental Science Olympiad! See below for a summary of our science event calendar. Practice questions (both Qualifying Exams and buzzer-based questions) can be found here at the high school level, and here at the middle school and elementary level. For further information on our science competitions, please contact alex@iacompetitions.com
During the 2026-27 school year, the International Science Bee’s European Division is open to students from Europe, Africa, the Caucasus, the Middle East, and Central Asia. Note that the International Science Championships and International Environmental Science Olympiad will not be held until 2028 and 2029 respectively – see below for details.
For the 2026-27 school year, the International Science Bee will feature two qualifying methods:
1. Qualifying Method A
Online Regional Qualifying Exam and Online Regional Finals
This qualifying method has two stages. The first is the Online Regional Qualifying Exam, which is offered free of charge to all students. Teachers, administrators, or parents begin by registering for the ORQE here, and then they will be sent a link to the ORQE that they can share with their student(s) or child(ren) when they’re ready to take it. There is no limit to how many students can take the ORQE at a school, and it consists of 50 basic-level multiple choice questions on all aspects of science. Students qualify automatically by reaching the following qualifying scores; if the exam is playing more challenging than the standard 60% pass rate, then the qualifying exam scores may be adjusted later in the school year until that threshold is reached; the threshold however will not be adjusted to a higher score than the scores posted here:
Varsity: Secondary school students born before 1 September, 2010 – Automatically qualify with a score of 75
Junior Varsity: Students born between 1 September, 2010 and 31 August, 2012 – Automatically qualify with a score of 65
Middle School: Students born between 1 September, 2012 and 31 August, 2014 – Automatically qualify with a score of 55
Elementary: Open to any student born 1 September, 2014 or thereafter – Automatically qualify with a score of 45
Sample International Science Bee Online Regional Qualifying Exam
Additional sample ORQEs from past years are available here on the USA Division website for practice.
The Online Regional Finals or Online Gold Set Science Bee is the second stage of this qualifying method. These are offered on three separate dates. The cost for the Online Fall and Online Spring Science Bees is $50 USD per student per tournament ($40 if all students at your school pay no tuition fees), with wire transfer and/or credit card fees applying per our policies.

2027 Online Gold Set Science Bee (together with players in North American & Asia!)
Date: Saturday, April 17, 2027
Gold Set Science Bee Question Set
Registration Opens Soon on the USA Website! Deadline: April 5, 2027
Note that the price of the Online Gold Set Science Bee is $56.70 USD (including credit card transaction fees) for all students.
Students who have passed the ORQE may compete at any of these tournaments. The Regional Finals and the Online Gold Set Science Bee consist of 4 rounds of 30 paragraph-length questions each, all of which are played with an online buzzer system. The questions progress from harder to easier information on any given science topic; the first student to buzz with a correct answer scores the point for that question.
Past National Science Bee questions (the content distribution is identical to that used in Europe) are available for practice here.
Once available, study guides will be posted on the Resources Page for the Regional Finals and for the Gold Set Science Bee.
The rules are identical to the International History Bee rules posted here, except students will go out at 6 points, not 8, in each round, and the bonus points will be adjusted accordingly. In the Online Gold Set Science Bee only, students will go out at 5 points.
All students play in the first 3 rounds; the final round is for the top students to determine the champions. There are four different age divisions for students (except in the Gold Set tournament which has 8 different age divisions), so that students ages 11-18 only compete with other students at most one year ahead or behind them in school. The top 2/3 of students in each age division then qualify for the European Championships. Note that while students may compete together against students from other regions in the Online Regional Finals and Online Gold Set Science Bee, the qualification is done both on the basis of top 2/3 of all students and the top 2/3 of just students from Europe.
2. Qualifying Method B
Championships Qualifying Exam
This qualifying method consists of the Championships Qualifying Exam (CQE) is offered at all in-person International History Bee and Bowl Regional Tournaments, and provides an alternate qualifying method for the International Science Bee to any students competing in these history tournaments. Interested competing students can take the Championships Qualifying Exam during the lunch break. The cost is 20 Euros, British Pounds, or Swiss Francs, or alternatively, 25 US dollars and may be paid in cash on the day of the tournament. The Championships Qualifying Exam consists of 50 multiple-choice questions on all aspects of Science; students have 20 minutes to take the Exam.
Two Exam Versions are offered: the Gamma Set CQE is given at in-person International History Bee and Bowl tournaments that run on the Gamma Question Set and the Beta Set CQE is given at in-person International History Bee and Bowl tournaments that run on the Beta Question Set.
Students qualify for the ISB European Championships, International Science Championships, and the International Environmental Science Olympiad by accomplishing one of the following things:
1. Finishing in the top half of students in their age division who take their respective version of the CQE at any given tournament site. If there is an odd number of students, or if two students tie for the last spot, we “round up” so that 4 students out of 7 would qualify, for example, unless there was a tie for 4th place, in which case 5 (or more, if more than two students tied for 4th) would qualify.
2. Students can also qualify by finishing in the top half throughout Europe among all students who take the CQE within their age division for any given exam. These median scores are calculated for Gamma and Beta Sets for all students who have taken an Exam by March 20.
Students only need to qualify once (either on either version of the Championships Qualifying Exam or at any of the Regional Finals Tournament) each year for the European Championships.

3. International Science Bee – 2027 European Championships
Students who qualify either through the Championships Qualifying Exam or the Online Regional Tournaments are then eligible to compete in the European Championships of the International Science Bee. The International Science Bee European Championships consists of in-person buzzer-based play with 3 rounds of 30 questions each with the top students advancing to a final round. The science-themed European Championship exams will be held on the same day, and our other European Championship events will be held at different times that weekend so qualified students can compete in all events they have qualified for.
You can find more information about the European Championships here.
Sample questions from the 2024 International Science Bee European Championships are found here on the Practice Resources Page.
4. The International Science Championships (ISC) is a week-long world championship-level event which will be held every two years, beginning in 2028. The 2028 ISC is planned for Washington, DC / Arlington, Virginia in the USA; subsequent ISCs will be held around the world. The International Science Championships will function similarly to the International History Olympiad and the International Geography Championships with a mix of science-themed buzzer-based quiz tournaments, exams, fieldwork and lab work, other competitions, ceremonies, and more. ISC will also feature a Family and Friends Program so that those accompanying students can take part in field trips and select competitions. Any student who qualifies for the International Science Bee European Championships also qualifies for ISC; students can qualify for ISC through the ISC Qualifying Exam. For further questions regarding the International Science Championships, please email help@iacompetitions.com.
5. The International Environmental Science Olympiad (IESO) is a week-long world championship-level event with an Environmental Science focus which will be held every two years, beginning in 2029. A pilot version of IESO was held in Puerto Rico in December 2024; subsequent IESOs will be held in the summer. The venue for IESO 2029 will be announced by the end of 2027. For students in the Varsity Division, IESO will function comparably to other international Olympiads with a science focus, in that each country or territory will be limited to a four-student team, accompanied by a national team coach. A process for how countries may form teams will be posted to the IESO website in 2027.
For students in the younger age divisions (Junior Varsity, Middle School, Intermediate, Elementary School), IESO will remain open to any student who has qualified for the preceding International Science Bee or National Science Bee regional championships for their respective region. In the case of European students, that means that anyone who qualifies for the 2025, 2026, 2027, 2028 or 2029 International Science Bee European Championships will also qualify for IESO provided they are age eligible.
For the younger age divisions, the International Science Championships will function similarly to the International History Olympiad and the International Geography Championships with a mix of environmental science-themed buzzer-based quiz tournaments, exams, fieldwork and lab work, other competitions, ceremonies, and more. IESO will also feature a Family and Friends Program so that those accompanying students can take part in field trips and select competitions. For further questions regarding the International Environmental Science Olympiad, please email help@iacompetitions.com.
