International Junior Science Olympiad (IJSO)

What is IJSO ?

The International Junior Science Olympiad (IJSO) is a competitive examination open to students of all countries in the world, primarily studying in secondary schools. All basic subjects of Science (Physics, Chemistry, Biology and Mathematics) are given roughly equal representation in the IJSO examination.

Eligibility (NSEJS)

All Indian students who are born on or after January 1, 2001 and, in addition, are in Class X or lower as of November 30, 2015, are eligible to appear in NSEJS 2015 - 2016. If they qualify in the NSEJS, they will be eligible for subsequent stages leading to participation in International Junior Science Olympiad 2015. It is the student's responsibility to ensure that the eligibility criteria are satisfied. In case at any stage of the program it is found that the student does not satisfy the eligibility criteria, he/she may be disqualified from the program.


The syllabus for NSEJS will be broadly equivalent to the secondary school level (upto Class X) of CBSE. The different basic subjects of science (physics, chemistry, biology and mathematics) will have roughly equal emphasis.This is only a broad guideline, and there is no detailed syllabus given for NSEJS.

Question Paper

NSEJS will emphasize comprehension of the subject, not rote memory. Its format will be as follows:The question paper will consist of 80 multiple choice questions, each with only one of the four options correct.Languag : English

Stages :

The Junior Science Olympiad program will follow the following 5 stages:

  • Stage I: National Standard Examination in Junior Science (NSEJS).
  • Stage II: Indian National Junior Science Olympiad (INJSO).
  • Stage III: Orientation cum Selection Camp (OCSC) in junior science.
  • Stage IV: Pre-departure Training Camp (PDT) for IJSO.>
  • Stage V: Participation in International Junior Science Olympiad (IJSO).

Stage I will be entirely the responsibility of IAPT. All the remaining stages will be organized by the HBCSE.


National Standard Examination in Junior Science (NSEJS) : NSEJS is the first stage of selection of students in the Junior Science Olympiad Programme. NSEJS is organised by the Indian Association of Physics Teachers (IAPT). Every student aspiring to go through successive stages of the programme must enroll for NSEJS. NSEJS is held at a large number of centres in the country.

Date of NSEJS 2015

22 November 2015 (Sunday)
Time of NSEJS 2015 : 03:00 pm to 05:00 pm

Qualifying for the Second Stage

Based on performance in NSEJS, the top 300 students in order of merit qualify to appear for the Second Stage of the Olympiad programme INJSO.
All students who qualify to appear for INJSO get a certificate of merit from IAPT.For any queries or clarifications and for any difficulties regarding enrollment for NSEJS, please contact:-

Stage II

Indian National Junior Science Olympiad (INJSO) INJSO will be organized by HBCSE at about 15 centres in the country.


Students selected from Stage I examination (NSEJS) are eligible to appear for INJSO. In addition those students who have been exempted as described in the Enrollment page are also eligible to appear for INJSO. Besides these two ways, there is no other way by which a student becomes eligible to appear for INJSO.
The tentative date and time of INJSO 2015 examination is as follows:

  • Date : January 30, 2016(Saturday)
  • Time : 01:00 pm - 04:00 pm (3 hours)
  • OCSCS : April- June 2016

The confirmed date and schedule will be announced in the first week of January 2016 on this website and communicated by post to the eligible students. Students appearing for INJSO will be eligible for TA/DA as per norms of the programme.


The syllabus for INJSO will be broadly similar to NSEJS. The syllabus is, however, only a broad guideline. Questions and problems in National Olympiads are usually non-conventional and of high difficulty level, comparable to International Olympiads. On the basis of performance in INJSO, the top 35 students in the merit list will be selected for Stage III: Orientation Cum Selection Camp (OCSC) in Junior Science.

Stage III

Orientation Cum Selection Camp (OCSC) in Junior Science OCSC in Junior Science will be organized by HBCSE sometime in April to June 2016 for 2-3 weeks. The precise dates will be announced prior to or along with the announcement of the selection list for the OCSC. The camp will include several theoretical and experimental tests. Orientation will be provided to students especially in experiments. The camp will conclude with a valedictory function where distinguished scientists will be invited to speak to the students.

The merit list of OCSC in Junior Science will be prepared on the basis of the combined theoretical and experimental score aggregated over all the tests in the camp, with 60% weightage for theory and 40% weightage for experiment. Performance in previous stages (NSEJS and INJSO) will not be a consideration for the merit list and awards of the OCSC.

The top 6 in the OCSC Junior Science merit list will be declared to be special merit awardees. These special merit awardees will be given Rs. 5,000 each in the form of books and cash. In addition, there will be special prizes to recognize meritorious performance in theory and experiments.

The 6 special merit awardees in Junior Science selected at the end of the OCSC 2016 will constitute the 6 member student team for the International Junior Science Olympiad (IJSO) 2015, provided they satisfy required criteria such as age limit, holding valid Indian passport, medical fitness, parental consent, etc.

Stage IV

Pre-departure Training (PDT) Camp for IJSO 2016
The selected 6 member student team will undergo a rigorous training programme at HBCSE in theory and experiment. Special laboratories are being developed at HBCSE for the purpose of experimental training. Resource persons from HBCSE and different institutions across the country will train the students.

Stage V

Participation in International Junior Science Olympiad (IJSO) 2016
The 6 member student team and 3 teacher leaders will constitute the delegation to represent India at the International Junior Science Olympiad (IJSO) 2016.
