NSEB (National Standard Examination in Biology)

The Association of Teachers in Biological Services (ATBS), in collaboration with the Homi Bhabha Center for Science Education (HBCSE) and the Indian Association of Physics Teachers (IAPT), conducts the National Standard Examination in Biology (NSEB). The National Standard Examination Board administers the NSEB examinations (NSE).

The NSEB test is part of the NSE (National Standard Examination), which organises national scientific olympiads to promote students, and provide a platform for them to compete in international competitions. Students who have not completed Class 12 are eligible to take this exam. The NSEB is conducted in a paper-based format. In this article, we’ve covered all you need to know about the NSEB 2023 test, including the curriculum, exam structure, eligibility requirements, and more.

NSEB 2023: National Standard Examination in Biology Stages

  • The NSEB is held to assess students’ biology skills and provide them with a platform to compete in international Olympiads. The NSEB Olympiad is divided into five phases. All the phases are mentioned here in detail:
  • The NSEB (National Standard Examination in Biology) is the first stage, and all students in grades 1 to 12 are entitled to participate after enrolling for the tests.
  • The Indian National Olympiad or Indian National Biology Olympiad is the second stage of the exam, and only 300 qualified students who scored higher than others are allowed to compete. INBO is held at 15 locations around the country.
  • In Biology, Stage 3 is the Orientation cum Selection Camp (OCSC), when the top 35 students from the merit list are chosen.
  • The top four students go to Stage 4, also known as Pre-Departure Training Camp (PDT). The training will last two weeks.
  • Students in Stage 5 compete in the International Biology Olympiad (IBO), and represent their school and country on a global scale.
