CBSE's free Science Challenge for Classes 8 to 10 opens for school registration on October 14, 2026, with round one in schools from November 2 to 13.
What Happened
The Central Board of Secondary Education (CBSE) has announced the Science Challenge 2026-27 for students of Classes 8 to 10 in its affiliated schools, through a circular dated Tuesday, October 13, 2026. Schools can register students from Wednesday, October 14, to Friday, October 30, 2026. The first round will be held in schools from November 2 to 13, followed by a computer-based second round for students the schools nominate. Taking part is free.
Key Facts
- The challenge is open to all students of Classes 8, 9 and 10 in CBSE-affiliated schools.
- Students cannot sign up on their own; their school must register them on the Science Challenge portal.
- School registration for round one runs from October 14 to October 30, 2026.
- Round one is held at school level from November 2 to November 13, 2026.
- Round two is computer-based and is scheduled for late November to early December; the published timetable lists November 30 to December 4, 2026.
- Schools nominate students for round two after round one.
- There is no fee for either round.
- Questions mix stimulus-based passages with multiple-choice items, and students are judged on both speed and accuracy.
Why It Matters
Most school science tests reward memory of the textbook. The Science Challenge is built differently. Stimulus-based questions give students a short passage, a graph or a situation and ask them to reason from it, which is closer to how science is used in real life and to the style of questions now appearing in board exams and entrance tests. For a student in Class 8, 9 or 10, it is a low-stakes way to practise that kind of thinking before the pressure of Class 10 boards or competitive exams.
Because the challenge is free and runs inside the school, it also reaches students who may not be able to pay for private olympiads or coaching-linked contests. The catch is that participation depends on the school. If a school does not register by October 30, its students miss the first round, so students and parents who are interested should ask their science teacher or principal early.
The two-round format also matters. Round one is run by the school, and only those the school nominates move on to the computer-based round two. Doing well in the school round is therefore the gateway, and students who want to reach the second stage should treat it seriously.
| Stage | Dates (2026) | Who takes part |
|---|---|---|
| School registration | October 14 to 30 | Schools register students |
| Round one | November 2 to 13 | All registered students, in school |
| Round two | November 30 to December 4 | Students nominated by schools, computer-based |
Impact
Short-term: Science teachers in CBSE schools will be busy registering students over the next two weeks and planning the school-level round in early November. Students get a fresh practice opportunity in reasoning-based science questions.
Long-term: Regular exposure to stimulus-based questions can help students prepare for competency-based questions in board exams and for entrance tests that reward application over recall. Schools that take part every year can use the results to spot students with an interest in science.
Who is affected: Students of Classes 8 to 10 in CBSE-affiliated schools, their parents, science teachers and school principals.
Key Takeaway
CBSE students in Classes 8 to 10 can take part in the free Science Challenge 2026-27 only if their school registers them between October 14 and October 30, 2026.
