National Standard Examination (NSE) 2025

The National Standard Examination (NSE) is one of the most prestigious science olympiads in India, conducted every year by the Indian Association of Physics Teachers (IAPT). It serves as the first step towards representing India at the International Science Olympiads (ISOs) in Physics, Chemistry, Biology, Astronomy, and Junior Science.

Every year, thousands of talented students across India participate in the NSE exams to test their scientific aptitude and problem-solving skills. The performance in NSE opens the gateway to the Indian National Olympiad (INO), then to Orientation-Cum-Selection Camp (OCSC), and eventually to the International Olympiads.

What is NSE?

The National Standard Examination is designed to identify and nurture scientific talent among school students. NSE exams are subject-specific, with each exam focusing on core areas of science:

• NSEP – National Standard Examination in Physics

• NSEB – National Standard Examination in Biology

• NSEC – National Standard Examination in Chemistry

• NSEA – National Standard Examination in Astronomy

• NSEJS – National Standard Examination in Junior Science

These exams are jointly referred to as IAPT Olympiads, as they are conducted by IAPT with support from HBCSE (Homi Bhabha Centre for Science Education).
