Starting with NSEJS, there are five competitive stages on the route to the International Junior Science Olympiad (IJSO) from India. The Indian National Junior Science Olympiad (INJSO) and the Orientation-Cum-Selection Camp (OCSC) are the next steps for qualified students.
The final step involves representing India at the IJSO after the top performers at OCSC are chosen for a pre-departure training camp. Every step assesses the student's knowledge of biology, chemistry, and physics as well as their capacity for analysis and problem-solving.
NSEJS 2026–27 – First round, conducted in November 2026
INJSO 2027 – Indian National Junior Science Olympiad for shortlisted candidates
OCSC – Orientation-cum-Selection Camp for top ~35 students
Pre-Departure Camp – Final preparation for the international stage
IJSO 2027 – International Junior Science Olympiad
8.0Awards & Recognition
IAPT and HBCSE grant certificates and merit awards to students who excel in NSEJS and later stages. Medals and recognition for excellence are given to those who meet the requirements for the OCSC through INJSO. Indian finalists in the International Junior Science Olympiad (IJSO) receive academic opportunities at prestigious scientific universities, national recognition, and international medals (Gold, Silver, or Bronze).
OCSC participants get Gold Medals and Merit Certificates
National and state toppers are recognised
The top 6 students from INJSO form the Indian IJSO team
9.0NSEJS 2026–27 Preparation Strategy
