The International Junior Science Olympiad (IJSO) is a competitive examination open to students of all countries in the world, primarily studying in secondary schools. In India it is jointly organised by two very prestigious bodies namely IAPT ( Indian Association of Physics Teachers)  and HBCSE ( Homi Bhabha Centre for Science Education). It’s a five stage process leading to International Junior Science Olympiad, Stage I will be entirely the responsibility of IAPT. All the remaining stages will be organized by the HBCSE. 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)


  • Open to students of all countries in the world, primarily studying in secondary schools.
  • Students  born on or after January 1, 2000 and, in addition, are in Class X or lower as of November, 2014, are eligible to appear in NSEJS 2014 – 2015.
  • If they qualify in the NSEJS, they will be eligible for subsequent stages leading to participation in International Junior Science Olympiad.


  • All students who qualify Stage 1 to appear for INJSO will get a certificate of merit  from  IAPT (around 300 students)
  • On the basis of performance in INJSO (Stage II), the top 45 students in the merit list will be selected for Stage III- Orientation Cum Selection Camp (OCSC) in Junior Science. The camp will include several theoretical and experimental tests
  • The top 6 in the OCSC Junior Science (Stage III) 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 selected 6 member student team will undergo a rigorous training programme at HBCSE in theory and experiment.
  • The student member team (two six member teams) and 3 teacher leaders will constitute the delegation to represent India at the International Junior Science Olympiad (IJSO) 2015.


  • Stage I: The question paper will consist of 80 multiple choice questions with equal weightage given to  physics, chemistry, biology and mathematics
  • Stage II: Questions and problems in National Olympiads are usually non- conventional and of high difficulty level, comparable to International Olympiads.


  • 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.


  • NSEJS(Stage I)       :    November 2014
  • INJSO(Stage II) :    February 2015
  • Orientation cum Selection Camp (Stage III) : May 2015
  • International Junior Science Olympiad (IJSO):December 2015
