IOAA 2021 Exam Date

IOAA 2021 Date

The key aim of the IOAA is to promote an increased interest in astronomy and related subjects, especially among young people, and to improve the development of international contacts between countries in promoting astronomy and astrophysics in schools. More bright high school students are predicted to be interested in studying astronomy at the university level as the next generation of astronomers as a result of events like IOAA.

Stages of IOAA Exam

The astronomy Olympiad programme is divided into five stages:

Stage I: National Standard Examination in Astronomy (NSEA),

Stage II: Indian National Astronomy Olympiad (INAO),

Stage III: Orientation cum Selection Camp (OCSC) in astronomy,

Stage IV: Pre-departure Training Camp (PDT) for IOAA,

Stage V: International Olympiad in Astronomy and Astrophysics (IOAA).
