The international Olympiad movement is aimed at bringing the most gifted secondary and higher secondary students of the world together in a friendly competition of the highest level. The Olympiads do not lead directly to any career benefits; rather, they provide a stimulus to begin a career in science or mathematics, to undertake a lifelong journey into the realms of exciting intellectual challenges. The national Olympiad programme follows a five and a six stage process, both for Science and Mathematics although the procedures are not exactly identical .
A major national Olympiad programme in basic sciences and mathematics which connects to the international Olympiads is in operation in India. The Homi Bhabha Centre for Science Education http://www.hbcse.tifr.res.in/is the nodal centre of the country for this programme. The programme aims at promoting excellence in science and mathematics among pre-university students.
Among the sciences, the Olympiad programme in Astronomy (junior and senior level), Biology, Chemistry, Junior Science and Physics is a five stage process for each subject separately. The first stage for each subject is organized by the Indian Association of Physics Teachers (IAPT) http://www.iapt.org.in/ in collaboration with teacher associations in other subjects. All the remaining stages are organized by Homi Bhabha Centre for Science Education (HBCSE).
The Mathematics Olympiad is conducted under the aegis of the National Board for Higher Mathematics (NBHM) http://www.nbhm.dae.gov.in/.
