What is Vidyasagar Science Olympiad?

** Vidyasagar Science Olympiad Scheme is a great initiative by School Education Department, Government of West Bengal and Jagadis Bose National Science Talent Search, Kolkata to identify and nurture the talented students of class IX towards strengthening the contribution of the students in our state in the national and international Olympiad examination and compete in the global platform.

** Students of class IX are of special significance as it is the period when students get preliminary exposure to the advanced level of every spectrum of science, be it Physical Science ( Physics and Chemistry of the materials), Life Science (Biology of living beings) or Mathematical science.

** If step taken to develop rational mind and scientific aptitude for students of this level, it will enrich human resources in the field of science and technology and strengthen the contribution of our State to the global level.

** To extract and identify the pre-madhyamik science talents (students of Class IX) from all corners of West Bengal a tri-layered examination system is designed.

** Early identification and nurturing through proper pedagogy, in turn will help us to tap the talent and modulate his/ her career paths in science and technology this will shape and enrich their in-depth scientific understanding and will help the students to pursue their carrier in science and to fit them in the global competition which in turn will be beneficial to enrich the pool of human resource from our state in the field of science and technology.
