Note: The IJSO 2022 is supposed to take place in December 2022 in Ukraine. But the dates have not been finalised yet. So, you will find information based on previous year's olympiads here.
Do you have an interest in science? Do you like Science experiments and research? Do you want to get the exposure to pursue a career in science one day? If you just said yes, then get ready for the International Junior Science Olympiad (IJSO). It is a big event and one of the most exciting olympiads conducted at an international level.
The International Junior Science Olympiad (IJSO) is an international individual and team competition conducted annually for students who are 16 years old on the 31st of December of the competition year. The main objective of this event is to promote Natural Science knowledge among students. It challenges and provides a platform for gifted students to showcase their talents and further deepen their knowledge. It also lets students from all over the world connect with one another and exchange ideas and knowledge. It also gives students and educators a chance to compare the syllabi being followed by different participating countries and understand the trends in Science education.
In India, the ISJO is conducted and coordinated by Homi Bhabha Centre for Science Education (HBCSE) in nearly 1400 schools across India. The HBCSE conducts this olympiad programme in 5 stages as given below:
The Indian Association of Physics Teachers (IAPT) organises this examination in coordination with the Association of Chemistry Teachers (ACT) and the Association of Teachers in Biological Sciences (ATBS).
The best-performing students (approximately 300 in each subject) in the NSE are selected for INO. HBCSE organises this olympiad in late January every year in around 18 centres all across the country. The syllabus of INO is the same as that of the NSE. However, it not only includes objective-type questions but also long-answer questions.
The top 35 students in each subject are selected for Orientation-cum-Selection Camps (OCSCs) held at the HBCSE from April to June. Students gain theoretical knowledge and experimental skills in this camp.
The students selected in the camps undergo training for the IJSO. Special laboratories have been developed in HBCSE for this purpose. Resource persons from different institutions across the country are invited to the training camps.
Finally, the 4-6 top performing students are selected to participate in the International Junior Science Olympiad. The students are accompanied by 2-4 teachers or mentors to the country where IJSO is taking place.
It is the student’s responsibility to determine if he/she satisfies the eligibility norms. If at some later stage it is found that the student does not meet the eligibility norms, he/she may face disqualification from the programme.
The syllabus for IJSO includes:

Set your pathway to success in the Science stream by preparing for IJSO with the askIITians team. We have the best mentors who will guide you and prepare you for the different stages of the International Junior Science Olympiad.
IJSO 2021 was held in UAE. IJSO 202 was held in Germany. IJSO 2019 was held in Qatar.
IJSO 2022 was supposed to be held in Ukraine (not confirmed). IJSO 2023 will be held in Thailand (confirmed).
The IJSO syllabus is almost similar to the Class X CBSE Science syllabus. But, students are expected to have advanced knowledge about the Science subject, not limited to the CBSE board.
You can consult your school authorities. They will guide you about the participation process. Visit the IJSO official website for more information.
