The Indian Institutes of Science Education and Research (IISER) will begin the registration process for undergraduate admissions for the 2026 academic session tomorrow, March 5, 2026. Students can apply online through the official admission portal iiseradmission.in once the application window opens.Every year, IISERs admit students to their science programmes through a national-level admission process. The institutes are known for combining undergraduate teaching with early research exposure. Students interested in careers in physics, chemistry, biology, mathematics and interdisciplinary sciences often apply to IISERs after completing Class 12.
IISER IAT 2026 : Eligibility criteria
Students who wish to apply must meet the basic eligibility conditions set by IISER.Candidates should have:
- Passed Class 12 or an equivalent examination in 2024, 2025 or 2026, or completed a minimum three-year diploma in the science stream
- Secured at least 60 per cent aggregate marks in Class 12 (55 per cent for Scheduled Caste, Scheduled Tribe and Persons with Disabilities candidates)
- Studied at least three subjects among Biology, Chemistry, Mathematics and Physics
Applicants must also provide correct academic and personal details while filling out the form.
IISER IAT 2026 : Selection process
Admissions will be conducted through different channels, including the IISER Aptitude Test (IAT) 2026, which is the main entrance test for many candidates.The IAT 2026 is scheduled to be held on Sunday, June 7, 2026. The exam will assess students in four core science subjects:
- Physics
- Chemistry
- Mathematics
- Biology
The test is designed to check conceptual understanding and problem-solving ability rather than simple memorisation.
