Homi Bhabha Centre for Science Education is the nodal centre of the country for Olympiad programmes in mathematics and sciences including astronomy. The programmes aim at promoting excellence in science and mathematics among pre-university students.
The Mathematics Olympiad is conducted under the aegis of the National Board of Higher Mathematics (NBHM).
From the Olympiad year beginning August 2008, a new integrated National Steering Committee for science and astronomy Olympiads has been overseeing the entire activity in these subjects. The subjects includes physics, chemistry, biology, astronomy, and junior science. The Olympiad programmes in physics, chemistry, biology, astronomy (junior and senior level) and junior science are a five stage process for each subject separately. The first stage for each subject is organized by the Indian Association of Physics Teachers (IAPT). All the remaining stages are organized by Homi Bhabha Centre for Science Education (HBCSE).
