About 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.

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.
