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.


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.



The aim of the first stage examination is to have a wide reach, to progressively increase this reach and to attain nationwide representation for Stage II without overly compromising on merit. Hence the selection for the Stage II examinations i.e. Indian National Olympiad Examinations (INOs) is based on the following scheme:

  1. Eligibility Clause:   To be eligible for the Stage II INO exam leading to the International Olympiad, a candidate must secure a score equal to or greater than a Minimum Admissible Score (MAS). The MAS for a given subject will be 50% of the average of the top ten scores in that subject rounded off to the nearest lower integer.


  1. Merit Index Clause:   There will be a high score called the Merit Index (MI) associated with each subject in Olympiads. The MI in a subject is defined as 80% of the average of the top ten scores in that subject rounded off to the nearest lower integer. All students with a score greater than merit index MI for the subject will automatically qualify for INO Stage II examination in that subject. For example, if the average of top ten scores in a certain subject is 92, then 80% of this is 73.6. Then the MI in that subject will be 73. All candidates with a score equal to or above 73 in that subject will automatically qualify for INO stage II.

  1. Proportional Representation Clause:   Students from all States and UTs need to be encouraged to appear for the first stage examination and a nationwide representation for INO Stage II is desirable. The quota for each State/UT used in National Talent Search Examination (NTSE) 2013-14, a nationwide competitive examination will be used as the baseline for calculating the number of students qualifying for Stage II INO in every subject from centres in that State or UT. Suppose the NTSE quota is S for a State, and the total for all States and UTs is T, then the total number of students to be selected to INO Stage II from that State would be S/T times 300, rounded off to the nearest higher integer. This number will include those selected on the basis of the Merit Index. In the event of tie at the last position in the list, all students with same marks at this position will qualify to appear for the INO Stage II examination. The selected students must nevertheless satisfy the eligibility clause. The number to be selected from all the centres in each State or UT will be displayed on the IAPT and HBCSE websites.



  1. Minimum Representation Clause:   Notwithstanding the proportional representation clause the number of students selected for INO from each State and UT must be at least one, provided that the eligibility clause is satisfied.

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

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 in the general education of young people and in all aspects of their lives. It is a purely educational event.


  • To promote and reward the pursuit of excellence in scientific endeavor.
  • 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.

  • To stimulate the active interest of students in the Natural Sciences.
  • To promote their careers 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.

IJSO Syllabus

The syllabus of the International Junior Science Olympiad (IJSO) lists the skills and areas of knowledge the participants should be familiar with for this competition.

It thus serves as a guideline for developing tasks to the Scientific Committees of the hosting countries but should also help the leaders of the participating countries to effectively train their students for this competition.

In order to keep the syllabus up to date it should be revalidated every three years and if necessary shortened or expanded.

Structure and content of the 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.

This conceptual approach is also meant to encourage the development of problems of interdisciplinary content and relevance.

The content of the syllabus is based on

  • The former syllabus of the IJSO,
  • The syllabi for students up to 15 years of age in the participating countries,
  • The problems given at the IJSO until the 5th IJSO in 2008.

Omissions and additions were made if considered suitable.

Remarks about problems given at the IJSO

More complex or additional topics may be investigated in the problems provided sufficient information to work on the questions is given in the problems themselves. This may include topics in science that are not listed below as well as the use of sophisticated apparatus in the experiments. The additional topics will not compose more than 10 % of any paper.

All Problems should be given using SI-units. If other units are used the conversion to SI-units should be explained. A list including all the natural constants used in the tests should be provided.

The experimental problems at the IJSO should only employ equipment that most of the students are familiar with and that may be found at schools. Furthermore they should not involve dissection of animals.
