IISER Aptitude Test (IAT) is an Indian computer-based test for admission to the various undergraduate programs offered by the seven IISERs, along with IISc Bangalore and IIT Madras.^[3] ^[4] ^[5] ^[6]

It is the only examination to get admission into the

5-year BS-MS Dual Degree Programs of the IISERs,
4-year BS Degree Programs of IISER Bhopal, and
4-year BS Program of IIT Madras.

It also serves as one of the channels to get admission into the 4-year BS Program of IISc Bangalore

IAT for IISERs

From 2024 onwards, admission to IISERs will be exclusively through the IISER Aptitude Test (IAT).^[7] There is no JEE Advanced channel or KVPY channel for admission in IISER anymore.

Test Pattern

IAT is conducted as a computer based test in the centers across India.

IAT consists of 60 questions: 15 questions each from Biology, Chemistry, Mathematics, and Physics.

Total time for answering the test is 3 hours. Questions are of multiple choice type with only one correct answer.

Each correct answer is awarded 4 marks.
Each incorrect answer leads to the deduction of 1 mark.
Unanswered questions are awarded 0 mark.
Therefore, maximum marks awarded in IAT are 240.

The total marks obtained by a candidate out of 240 is considered for preparing the Rank List.

Not every candidate appearing in IAT is awarded a rank. Rank cut-off is announced at an appropriate time. Further, getting a rank does not guarantee offer/admission to an IISER.^[8]

Syllabus

The syllabus generally follows the NCERT syllabus for classes 11 and 12. For 2024 exam, it will follow the rationalized syllabus of 2023-24.
