IJSO: Introduction


International Junior Science Olympiad (IJSO)

Crack this examination and entire world will know you as wizard

The International Junior Science Olympiad (IJSO) is an annual individual and team competition in the Natural Sciences for students who are under sixteen years old on 31st December of the competition year. IJSO has been established in recognition of the significance of the Natural Sciences.

Purpose of IJSO

To promote and reward the pursuit of excellence in scientific endeavour. To challenge, stimulate and encourage gifted students to further develop their talents in Natural Sciences. To create friendship and relationships among students around the world from an early age.

Exam Pattern

This is five-stage examination. Stages of the exam are as follows:

  • Stage 1: National Standard Examination in Junior Science (NSEJS)
  • Stage 2: Indian National Junior Science Olympiad (INJSO)
  • Stage 3: Orientation cum Selection Camp (OCSC) in junior science
  • Stage 4: Pre-departure Training Camp (PDT) for IJSO
  • Stage 5: Participation in International Junior Science Olympiad (IJSO)

Key Information

  • Stage-I: National Standard Examination in Junior Science (NSEJS)
  • Stage I will be entirely the responsibility of IAPT. All the remaining stages will be organized by the HBCSE. 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.
    Date of Examination: Last week of November

  • Stage-II: Indian National Junior Science Olympiad (INJSO)
  • 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 addition those students who have been exempted as described in the Enrolment page are also eligible to appear for INJSO.
    Date of Examination : Date of exam
    Duration of exam: 01:00pm-04:00pm (3hours)
    Syllabus: 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.

  • Stage-III: Orientation cum Selection Camp (OCSC) in junior science
  • 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. 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) Camps for IJSO
  • The selected Indian team will undergo a rigorous training programme at HBCSE in theory and experiment. Trained personnel and eminent personalities will be faculties to train the team of students.

  • Stage V: Participation in IChO
  • 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)

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.

Syllabus: The International Junior Science Olympiad is a general science competition. The IJSO syllabus is therefore not strictly divided into the disciplines biology, chemistry and physics but rather intends to highlight basic general concepts in science.
