In today’s competitive world, academic excellence goes far beyond classroom learning. One of the best ways for school students to measure their knowledge and skills at a higher level is through Olympiad exams. These exams take place at both national and international levels and are made to test students' thinking skills in subjects like Maths, Science, English, Computers, and General Knowledge.

Olympiads help students improve their knowledge of different subjects and also develop important skills such as problem-solving, thinking logically, reasoning well, and managing their time effectively. In India, many national Olympiad exams are held each year for students in classes 1 through 12, giving them a chance to present their abilities and get acknowledged.

In this blog, we will take a closer look at the list of national Olympiad exams happening in India during 2025-26. We’ll cover the dates of the exams, why they are important, and how to prepare effectively for them.

What is an Olympiad?

An Olympiad is a competition where students are tested on how well they understand concepts and can use their knowledge to solve real-life problems. School tests usually focus on getting high scores, but Olympiads are more about using logic and thinking deeply. Olympiads are held at different levels.

Olympiads are conducted at various levels:

School level – The first round starts at schools that are participating in the competition.
National level – Selected students qualify for state or national rounds.
International level – Top-performing students represent India on a global stage.

These exams are usually multiple-choice based and cover topics aligned with the school curriculum but at a deeper, more challenging level.

What are Olympiad Exams?

Olympiad exams are organised by different foundations, such as the Science Olympiad Foundation (SOF), Unified Council, Silver Zone Foundation, and the Indian Association of Physics Teachers (IAPT).

They assess students’ strengths in subjects such as:

Science Olympiad – Physics, Chemistry, Biology, Environmental Studies.
Mathematics Olympiad – Arithmetic, Algebra, Geometry, Logical Reasoning.
English Olympiad – Grammar, Vocabulary, Reading Comprehension, Writing Skills.
Cyber/Computer Olympiad – Digital literacy, coding, IT skills.
General Knowledge Olympiad – Current affairs, history, geography, environment, and reasoning.

These exams offer students certificates, medals, trophies, and even scholarships, so they are extremely useful for academic development.
