The National Standard Examination in Astronomy (NSEA) is conducted by the Indian Association of Physics Teachers (IAPT), which is one of the most important Olympiad exams in India. It is the initial stage of the International Astronomy and Astrophysics Olympiad (IOAA) that uses conceptual knowledge, analytical skill, as well as problem-solving skills of students in physics, mathematics, and astronomy at the high school level. Being the portal to the next stage of rounds, doing well in NSEA could lead to national training camps, specialized mentorship, and, finally, the possibility of representing India at the IOAA.
The National Standard Examination in Astronomy (NSEA) is a national-level exam involving prestige and administered by the Indian Association of Physics Teachers (IAPT). It is an annual event that is the initial part of the Astronomy Olympiad program in India, where top-achieving students are chosen to participate in the Indian National Astronomy Olympiad (INAO), and in due course, the International Olympiad on Astronomy and Astrophysics (IOAA). It questions the knowledge of students on the concepts of physics, mathematics, and astronomy.
