India at International Science Olympiads

1.1 What is an Olympiad?

An Olympiad is a yearly world contest in one subject for school students. Each country sends a small team. Students solve very hard problems and the best win gold, silver or bronze medals.

1.2 Which centre runs India's programme?

The Homi Bhabha Centre for Science Education (HBCSE) in Mumbai does. HBCSE is the nodal centre of the country for the Olympiad programme. A nodal centre is the one place that links everyone else. It finds, trains and guides the students.

1.3 Who pays for it and who is above it?

HBCSE is a national centre of the Tata Institute of Fundamental Research (TIFR). TIFR is an aided institution under the Department of Atomic Energy (DAE). For almost four decades, DAE has given the programme its institutional base.

Other departments also help. These are the Department of Science and Technology, the Department of Space and the Ministry of Education. A National Steering Committee set up by DAE oversees the national Olympiads.

2.1 What are the steps?

Thousands of school students sit the first exam. Only a handful fly abroad. The path in between has stages:

2.2 Who runs each stage in science?

A science Olympiad has five stages for each subject. The first stage is run by the Indian Association of Physics Teachers (IAPT), with teacher groups in other subjects. HBCSE runs the later stages for physics, chemistry and biology.

2.3 How is maths different?

The maths programme also has five stages. It runs under the National Board for Higher Mathematics (NBHM). Its first stage is the PRMO, held by the Mathematics Teachers’ Association (India). HBCSE organises all the later stages.

• Science: first stage by IAPT, later stages by HBCSE.
• Maths: first stage (PRMO) by the Mathematics Teachers’ Association, later stages by HBCSE.

3.1 Did India join every contest at once?

No. India started with maths and added the sciences over the next decade. The first years were maths in 1989, physics in 1998, chemistry in 1999 and biology in 2000.

3.2 What about astronomy?

The International Olympiad on Astronomy and Astrophysics (IOAA) was founded in 2007. The 18th edition was held in Mumbai from 15 to 21 August 2025. It was the largest so far, with nearly 300 students from 64 countries. This was the third time India hosted it.

India won 4 Gold and 1 Silver there.

3.3 What does it mean for exams?

Know the order of the first years. Maths came first, then physics, chemistry and biology. Astronomy’s world contest came last, in 2007.

4.1 What happened in physics?

The 56th International Physics Olympiad (IPhO) was held in Bucaramanga, Colombia, in July 2026. It had 381 students from 87 countries. All five Indian students won gold. This is called a Golden Sweep, which means every team member wins gold.

India shared the World No. 1 rank with China, Kazakhstan, Russia, South Korea and Taiwan.

• Kanishk Jain, Pune.
• Riddhesh Anant Bendale, Indore.
• Rishit Garg, Dwarka, New Delhi.
• Shresth Suraiya, Mumbai.
• Svarit Joshi, Ahmedabad.

4.2 Is this a one-year fluke?

No. Every Indian student at the IPhO over the last ten years has won a medal. HBCSE’s director said such wins are now routine. He credited patient mentoring over decades.

4.3 What happened in chemistry?

The 58th International Chemistry Olympiad (IChO) was held in Tashkent, Uzbekistan, from 10 to 19 July 2026. It was the biggest IChO so far, with 363 students from 93 countries. All four Indian students won gold.

It was India’s best IChO and its first all-gold haul. India tied for first place with China, Vietnam and a group of Russian students.

• Debadatta Priyadarshi, Bhubaneswar.
• Harshit Singla, Mandi Gobindgarh, Punjab.
• Kabeer Chillar, Delhi.
• Sandeep Kuchi, Hyderabad.

5.1 What happened in biology?

The 37th International Biology Olympiad (IBO) was held in Vilnius, Lithuania, in July 2026. It had 307 students from 78 countries. All four Indians won medals. It was India’s 26th appearance at the IBO.

• Gold: Bhavyaa Gunwal, Mahendragarh, Haryana.
• Silver: Soumil Maity, Nishit Kalani and Anmol Kumar.

5.2 What was the full 2026 total?

On 22 July 2026, DAE added up India’s results across the four big Olympiads. The total was 12 Gold and 7 Silver. The table has the details.

6.1 What is the maths story?

India’s maths story is the longest. It began with the first International Mathematical Olympiad (IMO) entry in 1989. India finished 25th and won 4 Bronze medals and 1 Honourable Mention. An Honourable Mention is a smaller award below the medals.

6.2 How did the rank change?

Progress was slow and uneven.

• 1998 and 2001: rank 7th both times. This stayed India’s best for over twenty years.
• 2017: a low of 52nd.
• 2024: best ever, 4th, with 4 Gold, 1 Silver and 1 Honourable Mention.
• 2026: 7th, in Shanghai, with 2 Gold and 4 Silver.

7.1 Which facts are asked most?

• Who: HBCSE, a national centre of TIFR, under DAE.
• Not: the Ministry of Education. It is only a partner.
• First years: maths 1989, physics 1998, chemistry 1999, biology 2000.
• 2026 cities: physics Bucaramanga, chemistry Tashkent, biology Vilnius, maths Shanghai.
• Golden sweeps: physics and chemistry.

7.2 Which mix-ups come up?

• Best IMO rank: 4th in 2024, not 1st.
• Astronomy: its world contest began in 2007, long after maths.
• 2026 total: 12 Gold and 7 Silver.
