International Chemistry Olympiad (IChO) is an annual event open to students of all countries in the world. ICho is a competition for students at the secondary and higher secondary school levels. 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 Chemistry Olympiad (IChO), Stage I will be entirely the responsibility of IAPT. All the remaining stages will be organized by the HBCSE. The Chemistry olympiad programme in India follows the following 5 stages:
  • Stage I: National Standard Examination in Chemistry (NSEC)
  • Stage II: Indian National Chemistry Olympiad (INChO)
  • Stage III: Orientation cum Selection Camp (OCSC) in Chemistry ,
  • Stage IV: Pre-departure Training Camp (PDT) for IChO,
  • Stage V: Participation in International Chemistry Olympiad (IChO)


  • Open to students of all countries in the world.
  • All Indian students who are born on or after July 1, 1995 and, in addition, are in Class XII or lower as of November 30, 2014, are eligible to appear for NSEC 2014 – 2015
  • Students who have passed Class XII are not eligible to enroll for NSEC.
  • If they qualify in the NSEC, they will be eligible for subsequent stages leading to participation in International Chemistry Olympiad.


  • All students who qualify NSEC ( Stage I)  to appear for the INPhO (Stage II) will get a certificate of merit from IAPT (around 300 students)
  • On the basis of performance in INChO, the top 35 students in the merit list will be selected for Stage III: Orientation Cum Selection Camp (OCSC) in Chemistry. The camp will include several theoretical and experimental tests.
  • The top 4 students in the OCSC chemistry merit list are declared to be special merit awardees. These special merit awardees are given Rs. 5,000/- each in the form of books and cash. In addition there are special prizes to recognize meritorious performance in theory and experiments
  • The selected 4 member  Indian team undergoes a rigorous training programme at HBCSE in theory and experiments.
  • The 4 member student team, 2 teacher leaders and 1 scientific observer constitute the delegation to represent India at the International Chemistry Olympiad (IChO).


The question paper will consist of 80 multiple choice questions


The syllabus for NSEC is broadly equivalent to the senior secondary level (Class XI and Class XII) of CBSE Chemistry.
