Introduction
Following the report on mathematics competitions, the international competition report series now turns to the sciences. Science competitions require students not only to master knowledge, but also to apply theory when observing and explaining the real world. The international competition systems associated with the three major disciplines of physics, chemistry, and biology have each developed mature selection methods and assessment frameworks.
This report focuses on physics, chemistry, and biology and selects competitions that currently attract strong participation from students at international schools in China and enjoy broad international recognition:
Physics: the U.S. Physics Bowl and the British BPhO series
Chemistry: the British UKChO and the Canadian CCC
Biology: the British BBO, the U.S. USABO, and iGEM
These competitions differ in question style, format, and assessment focus, but they share one core value: giving students an opportunity to test the depth of their thinking and broaden their horizons.
All information in this report is based on competition websites and materials released publicly by the organizers. It aims to help students and families understand the basic information for each competition, clarify their differences in difficulty and positioning, and identify the most suitable starting point and pathway.
At a Glance: Seven Science Competitions
The following overview presents key information on seven competitions across physics, chemistry, and biology. Readers can use it to establish a quick overall understanding before turning to the relevant section for details based on their grade level and goals.

Part I: Physics
A relatively clear progression has emerged for physics competitions at international schools in China. From introductory to advanced levels, students can select a starting point suited to their grade, curriculum progress, and target universities. This section introduces the British BPhO series and the U.S. Physics Bowl. They represent two distinctly different competition styles: BPhO emphasizes deep reasoning and the integrated use of mathematical tools, while the Physics Bowl emphasizes rapid judgment and fluency with knowledge.
I
The British BPhO Competition Series
1. Background and Core Value
The British Physics Olympiad (BPhO) is organized by the British Physics Olympiad Committee, with the University of Oxford Department of Physics participating in question setting and assessment. It is one of the United Kingdom's most authoritative physics competitions for secondary-school students and has long been regarded as an important academic indicator for applications to leading science and engineering programs in the UK.

The BPhO series is a complete, multi-level competition system. The Junior Physics Challenge (JPC) is designed for lower-secondary students. The Intermediate Physics Challenge (IPC) is for students in Grades 9–10, while the Senior Physics Challenge (SPC) is for students in Grades 10–11. Above these levels, BPhO Round 1 and BPhO Round 2 form the highest tier of the system.
In addition, BPhO Round 0 is a global preliminary round introduced in 2025. It serves as a qualification round and provides a supplementary pathway for students who did not participate in IPC or SPC, increasing their opportunity to progress to Round 1 and Round 2.
The value of BPhO operates on several levels. With the University of Oxford Department of Physics involved in question setting and assessment, the competition itself is an academic platform directly recognized by a leading international institution. From a global perspective, BPhO brings outstanding secondary-school students from dozens of countries together each year, making participation a large-scale intercultural academic exchange. In terms of capability development, its questions emphasize innovative thinking and complex problem-solving, providing training that can prepare participants for academic research at university. BPhO primarily uses proof-based problems, requiring students to construct complete lines of reasoning independently without relying on answer choices. Scoring considers not only whether the final answer is correct, but also the logical completeness of the argument, the clarity of each step, and the proper use of mathematical language.

2. Eligibility and Registration Requirements
IPC and SPC are open to students in the corresponding grade levels and serve as important preliminary stages leading to BPhO Round 1. Registration must be completed through a school or authorized test center; students cannot register individually.
Beginning with the 2026 season, the participation rules for the BPhO China Region, including Hong Kong and Macao, underwent a structural adjustment. Round 1 has a total quota of 3,500 participants in the China Region. Of these, 3,400 places are reserved for IPC or SPC award winners, while only 100 supplementary places are available to the top 100 students in BPhO Round 0.

3. Examination Format and Scoring
IPC and SPC offer both an online competition and an in-person written examination each year. The online competition consists of 40 multiple-choice questions worth one point each, lasts 60 minutes, and is less difficult than the formal in-person paper. The in-person IPC and SPC papers differ slightly and include multiple-choice, statement, and written-response questions. Each has a maximum score of 50 and lasts 60 minutes.
BPhO Round 0 lasts 60 minutes and consists of 25 single-answer multiple-choice questions for a maximum score of 25. Each correct answer earns one point, while incorrect or unanswered questions earn zero.
BPhO Round 1 comprises short-answer questions in Section 1 and extended-response questions in Section 2. The scoring criteria emphasize the logic of the solution process; a correct answer alone is insufficient for full marks. Beginning in 2026, the Round 1 examination was shortened from two hours and 45 minutes to two hours. The 45-minute reduction gives students an average of seven and a half fewer minutes for each of the six proof-based problems, substantially increasing the demands on pacing and rapid thinking.
4. Awards and Score Thresholds
The IPC and SPC online competitions each offer Gold, Silver, and Bronze awards. In 2026, the IPC Online thresholds were 22 or above for Gold, 14 or above for Silver, and eight or above for Bronze. The SPC Online thresholds were 28 or above for Gold, 22 or above for Silver, and nine or above for Bronze.
The in-person IPC and SPC examinations each offer Gold, Silver, Bronze I, and Bronze II awards. Awards are determined by global ranking: Gold goes to the top 5% of participants, Silver to the top 15%, Bronze I to the top 30%, and Bronze II to the top 45%. Score thresholds are set using the results of students in the UK. Students in China receive awards directly according to those thresholds, without a separate quota.
BPhO Round 1 offers both global awards and China Region awards. Global awards are determined by the performance distribution of students in the UK: Top Gold for the top 2%, Gold for the top 8%, Silver for the top 15%, Bronze I for the top 25%, and Bronze II for the top 40%. Students from other countries receive awards directly according to the same thresholds. Top Gold recipients are invited to BPhO Round 2, where awards are determined by global ranking, with Gold, Silver, and Bronze each accounting for approximately one third. Students from China may participate but are not eligible for selection to the UK national team.
5. Content and Scope of Knowledge
Although the BPhO series does not publish a fixed official syllabus, most of its content falls within secondary-school physics, with a small amount of introductory pre-university physics. The questions place substantial demands on mathematical tools and frequently involve differentiation, integration, and ordinary differential equations.
The scope primarily covers the following areas. Mechanics is central and includes kinematics, static equilibrium, dynamics, energy and momentum, oscillations, and waves. Electromagnetism covers electric fields, circuit analysis, magnetic fields, and their applications. Thermal physics and materials includes the physical properties of materials, the laws of thermodynamics, and thermodynamic cycles. Optics examines the core principles of geometrical and wave optics. Modern physics and astronomy includes atomic physics, nuclear physics, and basic astrophysics. At the AS level, foundational content covers mechanics, materials, waves, circuits, electric fields, momentum, data analysis, and nuclear physics. At the A2 level, advanced content includes circular motion, magnetic fields, the photoelectric effect, quantum mechanics, simple harmonic motion, and thermodynamics.
Notably, the BPhO Round 0 examination focuses on core AS-level knowledge, including mechanics, thermal physics, waves, and modern physics. It does not currently cover electric fields, magnetic fields, or gravitational fields.
6. Competition Schedule
The BPhO series follows a relatively consistent annual schedule. The IPC and SPC online competitions are generally held in late January, with the in-person competitions in early March. BPhO Round 0 is generally held in mid-October, offering a supplementary route for students who did not win an IPC or SPC award. The main BPhO Round 1 competition follows in early November and is the most important event of the year. Finally, BPhO Round 2 is held in late January of the following year and is open only to top performers invited from Round 1. For younger students, the JPC preliminary competition is generally held in mid-to-late November, followed by the final in mid-May of the following year.

II
The U.S. Physics Bowl
1. Background and Core Value
The Physics Bowl is organized by the American Association of Physics Teachers (AAPT). Since its launch in 1980, it has become one of the world's largest physics competitions for secondary-school students. Each year, more than 500 prominent secondary schools across 11 countries participate, and the competition attracts close attention from leading universities. More than 37% of students ranked in the global Top 100 in the Physics Bowl are admitted to U.S. Top 30 universities, while placing in the top 30% can be a meaningful addition to applications to institutions including Yale University, the Massachusetts Institute of Technology, the University of Oxford, and the University of Cambridge.
Source: AAPT official website
The core value of the Physics Bowl lies in its dual emphasis on speed and accuracy. Students complete 40 multiple-choice questions in 45 minutes, leaving only about 67 seconds per question. Unlike BPhO, the Physics Bowl more closely resembles the logic of standardized testing in U.S. university admissions: students demonstrate fluency with knowledge under strict time constraints. Its global ranking system also allows participants to evaluate their position objectively among international peers.
2. Eligibility and Registration Requirements
The Physics Bowl is open to students worldwide in Grades 9–12. It has two levels of difficulty. Division 1 is recommended for students in Grade 10 or below and covers Questions 1–40 of the 50-question paper. Division 2 is recommended for students in Grades 11–12 and covers Questions 11–50. Students cannot enter both divisions and should choose based on their grade and ability. Registration must be completed through the student's school or an authorized test center; individual registration is not available.
3. Examination Format and Scoring
The Physics Bowl is an individual written examination with no experimental component, and the paper is entirely in English. It lasts 45 minutes and contains 50 single-answer multiple-choice questions, of which each student answers 40. Each correct answer earns one point; incorrect or unanswered questions earn zero. The maximum score is 40.
4. New Policy and Score-Threshold Analysis
In 2026, AAPT took an unprecedented step for the Physics Bowl by eliminating the traditional global Top 100 ranking for the first time. Because the number of high-scoring students greatly exceeded previous years, AAPT included all students in both divisions who scored 38, 39, or the full 40 points on the global high-score list. This change sends two clear signals. First, score inflation at the top has become substantial: more than 100 students scored at least 38, and each score band included over 100 tied students, compressing the difference among top competitors to only one or two points and leaving almost no margin for error. At the same time, because so many students received identical scores, the organizer could not produce a more granular ranking and could only list perfect-score students alphabetically. This also means the absolute advantage once associated with a very high score is weakening, making it difficult for students to stand out in applications on the strength of a Physics Bowl result alone.
Source: AAPT official website
The 2026 national award thresholds for the China Region were as follows. In Division 1, the Top Gold Award, given to the national top 5%, required 34 points or above; Gold, for the top 15%, required 30 or above; Silver, for the top 30%, required 26 or above; and Bronze, for the top 45%, required 23 or above. In Division 2, the Top Gold threshold was 39 or above, meaning students could miss only one question on the 40-point paper. Gold required 36 or above, Silver 31 or above, and Bronze 27 or above.
Source: Physics Bowl China Region official website
Compared with 2025, score thresholds rose significantly in 2026. In Division 2, for example, 28 points was sufficient for Gold in 2025, whereas 31 points earned only Silver in 2026. This change indicates that the overall level of participants continues to rise and the number of high-scoring competitors has grown considerably. Regional award thresholds are set independently for North China, South China, East China, Central China, and West China.
5. Content and Scope of Knowledge
The Physics Bowl covers the core content of secondary-school physics, with approximately 90% alignment with the physics content of A-Level, IB, and AP courses, along with a small number of general physics questions. Mechanics, which accounts for approximately 45%, includes the fundamentals of measurement, kinematics calculations, Newton's three laws, momentum, impulse, kinetic energy, energy conversion, circular motion, fluid mechanics, and other topics. Electromagnetism includes waves, Coulomb's law, electric fields, electric potential, electric potential energy, capacitance, parallel-plate capacitors, and Gauss's law. Thermal physics covers ideal gases, internal energy, heat engines, and molecular motion. Optics includes geometrical and wave optics. Modern physics covers atomic structure, quantum mechanics, and wave–particle duality.
Division 1 emphasizes foundational applications, at a level comparable to AP Physics 1 and part of AP Physics 2. Building on Division 1, Division 2 adds advanced content including special relativity, the fundamentals of quantum mechanics, and wave mechanics, bringing its difficulty close to AP Physics C and preliminary International Physics Olympiad problems.
III
Comparing Physics Competitions and Choosing a Path
Although BPhO and the Physics Bowl are both physics competitions, their assessment logic is fundamentally different. BPhO primarily uses proof-based problems, emphasizes logical reasoning and complete written steps, and places substantial demands on the use of mathematical tools. It more closely resembles the study of physics at university: students must break a complex problem into layers and present their reasoning in precise mathematical language. The Physics Bowl consists of multiple-choice questions and tests whether students can work quickly and accurately. In short, BPhO pursues depth, while the Physics Bowl prioritizes speed and fluency.
In terms of the difficulty curve, BPhO spans a wider range from foundational to advanced content, with its final questions approaching introductory university physics. The upper limit of Physics Bowl Division 2 is approximately the level of AP Physics C. Of particular importance, BPhO quotas in the China Region tightened substantially beginning in 2026. Students must earn an SPC award in Grades 10–11 to qualify for Round 1, which means preparation for BPhO extends over a longer period than preparation for the Physics Bowl and must begin a year earlier.
The right choice therefore depends on the type of thinking at which a student excels. Students who enjoy constructing a complete derivation from first principles may find BPhO more suitable. Those who react quickly and make strong judgments under pressure may perform better in the Physics Bowl. Many students also pursue both tracks, using the Physics Bowl in Grade 11 to test speed and fluency before attempting BPhO in Grade 12 to demonstrate deep reasoning. The competitions are not mutually exclusive; they complement one another through a balance of pace and depth.
Part II: Chemistry
This section introduces the Canadian CCC followed by the British UKChO. The former is suitable for students encountering chemistry competitions for the first time and can help them build confidence through participation. The latter is an option for older students seeking a highly demanding challenge that creates greater differentiation.
The Canadian CCC
1
Background and Core Value
The Canadian Chemistry Contest (CCC) is organized by the Chemical Institute of Canada (CIC) and is one of Canada's most authoritative chemistry competitions for secondary-school students. It also serves as the national preliminary competition for the Canadian Chemistry Olympiad (CCO).
Source: CIC official website
Alongside UKChO and USNCO, the CCC is regarded as one of the three major international chemistry competitions, and its results enjoy broad academic recognition worldwide. Leading universities including the University of Cambridge and the Massachusetts Institute of Technology list it among recommended competitions, and it carries substantial reference value for applications to science and engineering programs at universities in Canada, the United States, the United Kingdom, and China.
The core value of the CCC lies in its accessible and inclusive positioning. Its questions emphasize mastery and straightforward application of foundational knowledge and do not involve first-year university chemistry. For students in Grades 9–10 and those just beginning to explore chemistry competitions, the CCC is an ideal entry point, allowing them to become familiar with competition question types and pacing while building confidence in a low-risk setting.
2
Eligibility and Registration Requirements
The CCC is open to students in all secondary-school grades. Students in China may register through a participating school or authorized test center. The CCC has two stages: a national preliminary competition, followed by an invitation-only final, the CCO, for high-performing students from the preliminary round. More than 12,800 students participated worldwide in the 2026 season, including more than 3,000 registrants in the China Region.
3
Examination Format and Scope
The CCC lasts 60 minutes and consists of 25 single-answer multiple-choice questions. Correct answers earn points, while incorrect answers carry no penalty. The content is grouped into eight modules: safety, organic chemistry, acids and bases, structure and properties, electrochemistry, solutions and stoichiometry, gas laws and prerequisite fundamental concepts, thermochemistry, reaction kinetics, and chemical equilibrium.

4
Awards
CCC awards are divided into two levels: the Global Excellence Award and national awards. The Global Excellence Award is given to participants whose scores exceed the threshold for the top 10% in Canada. National awards are determined by performance ranking in the China Region: Gold is awarded to the top 10%, Silver to the top 25%, and Bronze to the top 35%.
The British UKChO
1
Background and Core Value
The UK Chemistry Olympiad (UKChO) is organized by the Royal Society of Chemistry (RSC). It is the United Kingdom's longest-running and most influential chemistry competition for secondary-school students. The competition provides students worldwide with an academic chemistry challenge extending beyond the school curriculum and develops chemical thinking and the ability to solve complex problems.
Source: RSC official website
The core value of UKChO lies in its positioning as a competition of high difficulty and strong differentiation. Approximately 40% of its content involves first-year university chemistry, meaning that nearly half the paper extends beyond the A-Level and IB Chemistry curricula. Students must rely on independent study and their ability to transfer knowledge beyond the classroom. Questions frequently draw on original papers from leading journals and test students' ability to apply knowledge and solve problems at the frontiers of science.
In the 2026 competition, only about 8.5% of participants received Gold—approximately one in every 12 competitors. This scarcity gives the award a high degree of differentiation in applications to leading universities.
Source: UKChO official website
2
Eligibility and Registration Requirements
UKChO is open to students in Grades 10–12, generally from curricula including A-Level, IB Higher Level, or AP, and requires a solid foundation in chemistry. Chinese nationals may participate only in Round 1 and are assessed using the same paper and scoring standards as students in the UK. Rounds 2 and 3 are open only to British nationals and select the team representing the UK at the International Chemistry Olympiad (IChO). Registration must be completed through a school or officially authorized channel; individual registration is not supported.
3
Examination Format and Scoring
Round 1 is an individual written examination with no experimental component, and the questions are in English. The examination lasts two hours and consists of five to six analytical short-answer problems, each containing three to ten subquestions. The total score varies slightly from year to year and generally falls between 80 and 90 points. UKChO is known for its difficulty and focus on frontier topics, with an emphasis on students' ability to transfer knowledge and solve advanced scientific problems. Scoring considers not only the final answer but also the logic of the process; even when a final numerical value is incorrect, a correct derivation can still earn substantial credit.
4
Awards and Score Thresholds
UKChO offers Gold, Silver, and Bronze awards. Score thresholds are first set using the results of British nationals, and students from other countries receive awards according to the same thresholds.
Results for UKChO Round 1 in 2026 were officially released on March 20. The threshold for Gold was 38 or above out of 84, Silver covered scores from 23 to 37, and Bronze covered scores from 13 to 22. Globally, approximately 8.5% received Gold, 25.7% Silver, and 36.5% Bronze. In 2026, more than 17,000 students from over 1,153 schools participated worldwide, setting a record. The Gold threshold rose sharply from 29 points in 2025 to 38 in 2026. A nine-point increase means students needed to answer nearly two additional major problems correctly—a qualitative leap in the context of UKChO's difficulty.
Source: UKChO China Region official website
The principal reason for the higher thresholds was a moderation in the overall difficulty of the 2026 paper. A greater proportion of accessible questions placed more emphasis on solid mastery of core A-Level knowledge. At the same time, the overall standard of participants continued to rise, with a larger share of high-performing students competing more intensely on a relatively approachable paper, pushing the thresholds upward.
5
Content and Question Distribution
UKChO covers four broad fields: inorganic chemistry, physical chemistry, analytical chemistry, and organic chemistry. Based on analysis of recent examinations, its content can be summarized in five major question types.
Source: UKChO China Region official website
Integrated organic chemistry accounts for approximately 40%–50%, covering complex synthetic-route design, reaction mechanisms, spectral analysis, and stereochemistry, and is the paper's clear priority. Physical chemistry calculations account for approximately 15%–20%, focusing on thermodynamics, kinetics, and electrochemistry, and often appear as the final, most difficult problem. Inorganic chemistry inference accounts for approximately 10%–15%, emphasizing transition-metal complexes, coordination chemistry, and applications of periodic trends. Reaction-mechanism analysis accounts for approximately 10%–15% and requires students to derive unfamiliar mechanisms. Experimental design and data analysis account for approximately 10%, assessing error analysis, yield calculations, and experimental planning through laboratory scenarios. Organic chemistry is the key to success, and preparation requires substantial time for in-depth study and extensive practice.
6
Competition Trends
Several important trends emerged in UKChO in 2026. Participation continued to grow, intensifying competition; the Gold threshold rose sharply, reflecting a general improvement among top students; and question style increasingly emphasized solid mastery of foundational knowledge and rigor in the solution process rather than difficulty for its own sake.
Comparing Chemistry Competitions and Choosing a Path
The progression from CCC to UKChO provides a clear pathway. The CCC is closer to an extension of the secondary-school curriculum. UKChO presents a challenge on an entirely different scale, with approximately 40% of its questions involving first-year university chemistry.
The choice between them is straightforward. Students who have not yet studied A-Level or IB Higher Level Chemistry are not advised to attempt UKChO directly; beginning with the CCC is more reliable. Students with a solid foundation in chemistry who intend to pursue chemistry, medicine, pharmacy, or related fields may find a UKChO Gold award a highly distinctive academic credential. A common preparation strategy is to enter the CCC in Grade 10 as an initial test, then attempt UKChO and pursue Gold in Grade 11. The CCC serves as a mock competition, allowing students to experience competition pacing and build practical experience for UKChO.
Part III: Biology
Biology competitions offer two parallel pathways: individual written examinations and team-based research. This section introduces BBO, USABO, and iGEM. BBO tests speed, USABO tests depth, and iGEM uses a team research project to assess scientific thinking, collaboration, and interdisciplinary integration.
The British BBO and the U.S. USABO
1
Background and Core Value
In secondary-school biology competitions, the British Biology Olympiad (BBO) and the USA Biology Olympiad (USABO) are widely recognized as two of the world's most prestigious events. BBO is organized by the Royal Society of Biology and is recognized by universities throughout the Commonwealth and around the world. USABO is organized by the Center for Excellence in Education and carries substantial weight in applications to leading U.S. universities.
Source: RSB official website
Source: USABO official website
The value of BBO and USABO lies in the highly complementary dual-competition system they create. Their content overlaps by as much as 90%, reflecting the similarities between foundational biology education in the United Kingdom and the United States. Whether in the British A-Level curriculum or the U.S. AP curriculum, the core framework of biology—cell biology, genetics and evolution, ecology, anatomy and physiology, and related fields—rests on common foundations. Although the competitions are organized by different institutions, their underlying approach to question design is therefore highly similar. The principal distinction lies in format: BBO challenges students with volume, while USABO distinguishes itself through depth. This allows students to prepare for both examinations within the same cycle, offering exceptional efficiency for the time invested.

2
Eligibility and Registration
BBO and USABO are open to students in all secondary-school grades. Participants must register through their school or an authorized test center; neither competition offers individual registration. The China Region is organized centrally by an officially authorized institution. According to official 2025 data, more than 15,000 students participated in BBO worldwide, including approximately 7,500 students in the China Region—around half the global total.

Examination Format
In 2026, the BBO and USABO examination dates were separated for the first time, creating favorable conditions for students preparing for both. BBO was held in January, lasted 90 minutes, and consisted primarily of multiple-choice questions. In recent years it has included approximately 160–200 questions, leaving an average of only about 30 seconds per question. USABO was held in April, lasted 50 minutes, and contained 50 single-answer multiple-choice questions.
4
Content
BBO and USABO have substantial overlap in content and both cover the core fields of biology, including animal anatomy and physiology, cell biology, genetics and evolution, plant anatomy and physiology, ecology, animal behavior, and biosystematics. Their main difference is that BBO emphasizes breadth of knowledge and speed through a larger number of questions, while USABO places more emphasis on depth of knowledge and logical reasoning, with greater difficulty at the individual-question level.

Awards
BBO score thresholds are set using the results of British nationals, and students from other countries receive awards according to the same thresholds. Awards in the USABO China Region include Gold, Silver, Bronze, and Regional Honorable Mention, with the proportions determined by the number of participants in the relevant year. Certificates from both competitions carry substantial reference value for applications to biology, medicine, bioengineering, and related programs.

The International Genetically Engineered Machine Competition (iGEM)
1
Background and Core Value
The International Genetically Engineered Machine Competition (iGEM) was founded at the Massachusetts Institute of Technology in 2003 and developed into an international academic competition in 2005. It is the world's most influential international academic competition in synthetic biology, and its events and research outcomes receive annual attention and coverage from leading academic journals including Science and Nature, as well as mainstream media. Since its founding in 2003, iGEM has attracted more than 86,000 participants worldwide. Its scale and influence lead comparable research competitions: participants have produced more than 4,600 innovative projects and built a shared database containing over 75,000 standardized biological parts.
Source: iGEM official website
The core value of iGEM is that it offers a path entirely different from an individual written examination. BBO and USABO assess the breadth of students' biological knowledge, while iGEM requires students to experience the complete cycle of a research project, from selecting a topic and designing experiments to collecting data and presenting results.
2
Eligibility and Team Requirements
iGEM is open to students worldwide in Grades 9–12 and is divided into high school, undergraduate, and graduate divisions. Participants register as teams, typically comprising 15–20 members, and teams may include students from different grades, schools, and regions. Each team must be supervised by a primary principal investigator. In the high school division, the primary principal investigator must be a teacher or administrator at the participating school.
Source: iGEM official website
3
Competition Format
iGEM is a team-based research project competition in which participating teams must complete the following work within one year. They select their own topic focused on a real-world problem in areas such as the environment, medicine, energy, or agriculture; design and implement a synthetic-biology experimental plan; deepen the project through mathematical modeling, software programming, hardware development, and related methods; and conduct human practices through research, science communication, public engagement, and other activities. Finally, teams build a project Wiki, produce a promotional video, and prepare presentation and defense materials. Teams are generally divided by function into a wet-lab group responsible for experiments, a dry-lab group responsible for modeling and data analysis, and a human-practices group responsible for research and outreach.
Source: iGEM official website
4
Schedule
The iGEM competition cycle lasts approximately one year. From January through April, teams form, select topics, and study foundational knowledge. From May through August, they conduct experiments and collect data. From September through October, they integrate results, build their Wiki, and prepare for presentations. The Grand Jamboree is held in November. The 2026 Grand Jamboree is scheduled for November 13–16 in Paris, France.
5
Awards
The iGEM award system has three levels. Medals are awarded at Gold, Silver, and Bronze levels using progressive criteria: a team must first satisfy the Bronze requirements before becoming eligible for Silver and Gold. Special Prizes recognize outstanding work in particular areas and include Best Model, Best Education, Best Entrepreneurship, Best Hardware, and Best Sustainable Development Impact, among others. The Grand Prize is the highest honor in each division—high school, undergraduate, and graduate. There is no fixed limit on the number of iGEM awards; any team meeting the relevant criteria can receive one. Teams from China have performed strongly in recent years. In 2024, Chinese teams won 106 Gold medals, accounting for 51% of all Gold medals worldwide.
Comparing Biology Competitions and Choosing a Path
BBO and USABO assess the depth and breadth of students' biological knowledge. iGEM, by contrast, asks whether students can work like genuine researchers—from identifying a worthwhile question and designing an experimental plan to carrying out procedures, analyzing data, and communicating results to the public. For students seeking a rapid assessment of their subject knowledge, an individual written examination is an efficient choice. For those wishing to demonstrate independent research capability and team leadership, iGEM provides a path that written examinations cannot replace. In terms of timing, students in Grades 9–10 can first build a solid disciplinary foundation through BBO and USABO, then participate in iGEM in Grades 11–12 to demonstrate their research potential through a complete project experience.
Conclusion
The value of science competitions is often reduced to a certificate or a line on a résumé. What truly deserves to be remembered, however, are the recurring moments during preparation when students face a problem they have never seen and that was never taught in class, yet must find an approach, complete a derivation, and state a conclusion within an hour. Physics, chemistry, and biology offer different competition pathways, but their underlying logic is shared. When participants encounter a real-world problem, can they identify its disciplinary essence and draw on what they already know to construct a solution? Training this capability is almost impossible to replicate in an ordinary classroom.
It is important to recognize that the value of competitions is not proportional to the number entered. Across physics, chemistry, and biology, the key question is not how many competitions a student joins, but which competitions they choose. At their core, competitions should help students discover their academic interests and patterns of thinking, not encourage them to accumulate credentials without direction. Rather than sample many paths superficially, students are better served by going further and deeper along one path suited to them. This restraint and focus may be the wisdom in competition planning that matters more than simply collecting awards.
