IISER IAT 2026 Eligibility Criteria and Application Tips
To be eligible for IAT 2026, candidates must have passed Class XII or equivalent from a recognised board in India or abroad, or be appearing in 2026. Applicants must have studied at least three of the subjects: Physics, Chemistry, Mathematics, and Biology at the Class XII level. Specific programmes, such as BTech and computational science courses, require Mathematics as a mandatory subject. Foreign nationals must provide an equivalence certificate from the Association of Indian Universities (AIU) if their qualification doesn’t match Indian board standards. Candidates are advised to prepare strong conceptual knowledge in Physics, Chemistry, Mathematics, and Biology as the aptitude test evaluates problem-solving ability across these areas.
