The Indian Institute of Science Education and Research (IISER) has opened the application process for the IISER Aptitude Test (IAT) 2026. Students seeking admission to the country’s prestigious science institutes can now apply online.

IISER is one of the country’s leading institutes, providing an environment for scientific research and high-quality education.

Therefore, the IAT exam, conducted for admission to IISER, is considered crucial for students.

The Application Process Started on March 5th

The application process for the IISER Aptitude Test 2026 began on March 5th, 2026. Interested and eligible candidates can apply online by visiting the official website, iiseradmission.in. The deadline for applications is April 13, 2026.

Students are advised to complete the application process well in advance, without waiting for the deadline, to avoid technical issues.

Which IISER Institutes Will Offer Admission?

IAT 2026 will offer admission to undergraduate programs at seven leading IISER institutes in the country. These institutes include:

Admission in the 2026-27 session will be based solely on the IAT score.
