About IJSO


Junior Science Olympiad Dates: May 16 - June 01, 2013


INJSO 2013 Question Paper and Answers:



The International Junior Science Olympiad (IJSO) is an annual individual and team competition in the natural sciences for fifteen -year-old students. It has been established in recognition of the significance of the natural sciences in the general education of young people and in all aspects of their lives. It is a purely educational event. No country may have its delegation excluded from participation on political grounds, lack of diplomatic relations, lack of recognition by the government of the organizing country, imposed embargoes or similar reasons. When difficulties preclude formal invitation of the delegation representing a country, student from such a country should be invited to participate as individual delegations. Religious or political propaganda against any person or country or disruption of any aspect of the IJSO is strictly forbidden. Participation in the IJSO either by a host country, a delegation or an observer signifies acceptance of the statutes and all other accepts of the IJSO.





The objectives of the IJSO


  • To stimulate the active interest of students in the natural sciences.
  • To promote their career as scientists.
  • To enhance and develop international contacts in the natural sciences.
  • To promote future scientific collaboration.
  • To encourage the formation of friendships within the scientific community.
  • To offer the opportunity to compare the syllabi and educational trends in science education within the participating countries.






The aims of the IJSO


  • To promote and reward the pursuit of excellence in scientific endeavor.
  • To challenge and stimulate gifted science students to develop their talents.
  • To select the top young science student teams at the annual IJSO.
  • To encourage continued participation in the study of the natural sciences.
  • To create the friendship and relationship among students around the world from his/her early age.



Stages Of IJSO



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.


The detailed information about eligibility and structure of the stages is given below:



Stage I: 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.



Eligibility (NSEJS):


All Indian students who are born on or after January 1, 1996 and, in addition, are in Class X or lower as of November 30, 2010, are eligible to appear in NSEJS 2010 – 2011. If they qualify in the NSEJS, they will be eligible for subsequent stages leading to participation in International Junior Science Olympiad 2011.


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.


Language : English.



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. In case there is a tie at the last position, all students with the same marks at this last position qualify for INJSO.


All students who qualify to appear for INJSO get a certificate of merit from IAPT.

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 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.In the event, there is a tie at the last position, all students with the same marks at this last position will qualify for OCSC in Junior Science.


There will be no other criterion or provision for selection to OCSC.




Stage III: Orientation  Cum Selection Camp (OCSC) in Junior Science



OCSC in Junior Science will be organized by HBCSE sometime in April to June  for 2-3 weeks. The precise dates will be announced prior to or along with the announcement of the selection list for the OCSC.



Eligibility for OCSC :


Only the students selected from the merit list of Stage II (INJSO) will be eligible for OCSC  in Junior Science. There will be no other criterion or provision.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  will constitute the 6 member student team for the International Junior Science Olympiad (IJSO) , 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


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)


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


The 8th IJSO will be held in Durban, South Africa tentatively in December 2011.
