IAPT Exams 2025: Complete Guide to NSEP, NSEC, NSEB, NSEJS & Other Olympiads

The Indian Association of Physics Teachers (IAPT) is one of India’s most respected academic organizations, known for conducting high-level national science examinations that serve as the foundation for International Olympiads in Physics, Chemistry, Biology, and Junior Science.

Every year, lakhs of students across India participate in IAPT exams such as NSEP, NSEC, NSEB, NSEJS, and more. These exams identify the country’s brightest scientific minds and train them for global competitions like IPhO, IChO, IBO, and IJSO.

What is IAPT?

The Indian Association of Physics Teachers (IAPT) was established in 1984 by a group of dedicated physics educators, including the renowned scientist Dr. D.P. Khandelwal.
Its mission is to promote the study of physics and to conduct fair, high-quality examinations that help identify talented students across India.

IAPT collaborates with:

• HBCSE (Homi Bhabha Centre for Science Education, TIFR)

• NBHM (National Board for Higher Mathematics)

Together, they run the Indian Olympiad Programme.
