If you’re someone passionate about science and looking to build a robust career in research and education, the Indian Institutes of Science education and Research (IISERs) could be your perfect destination. With a strong academic reputation, world-class research facilities, and a focus on interdisciplinary science education, IISERs provide an excellent platform for aspiring scientists.
In 2026, the IAT (IISER Aptitude Test) will once again open the doors to these prestigious institutions. Here’s everything you need to know about the IAT 2026, the admission process, and the courses offered by IISERs for students after 12th.
1. What is IISER?
The Indian Institutes of Science education and Research (IISERs) are a group of premier institutions in india dedicated to providing quality education in the sciences. These institutes focus on fostering a research-driven approach to education, making them ideal for students interested in pursuing careers in basic sciences like Physics, Chemistry, Biology, and Mathematics.
There are currently seven IISERs across India:
· IISER Pune
· IISER Kolkata
· IISER Mohali
· IISER Bhopal
· IISER Thiruvananthapuram

· IISER Berhampur
These institutions are known for their cutting-edge research, world-class faculty, and state-of-the-art laboratories.
2. Courses Offered at IISERs After 12th
IISERs offer a range of undergraduate and postgraduate courses that focus on basic sciences, as well as interdisciplinary research. Here's a breakdown of the most popular courses:
· BS-MS Dual Degree:
o The BS-MS (Bachelor of Science - master of Science) dual degree program is the flagship undergraduate program at IISERs. students will earn both a Bachelor’s and a Master’s degree in Science after completing five years of study.
o The program is offered in fields like Physics, Chemistry, Biology, and Mathematics.
· PhD Programs:
o IISERs also offer PhD programs for students who wish to pursue research in specialized scientific fields. These are open to students who complete their MS/BS or have a master’s degree in any scientific discipline.
· Interdisciplinary Research:
o One of the unique features of IISERs is the opportunity for students to engage in interdisciplinary research, blending subjects like Biophysics, Chemical Biology, and Astrophysics.
3. What is the IISER Aptitude Test (IAT)?
The IISER Aptitude Test (IAT) is the entrance exam for admission to the BS-MS dual degree program at IISERs. If you are aiming to study at an IISER after your 12th, the IAT is the primary entrance exam to gain admission. Here’s what you need to know:
· Mode of the Exam: The IAT is a computer-based test.
· Test Duration: The exam lasts for 3 hours.
· Subjects Covered: The exam tests knowledge in the following subjects:
o Physics
