CAT Score Weightage in IIMs 2026
CAT score weightage plays a major role in the IIM Admission Criteria but it is not the same across all institutes. Each IIM follows its own admission criteria, with CAT carrying different weightages during pre-PI shortlisting and final selection. While some IIMs assign around 25–30% weightage to CAT in the final selection, others give it 50% or more. Understanding the CAT weightage in IIMs 2026 can help aspirants evaluate their admission chances and target institutes more strategically.
CAT Weightage in IIM Selection Criteria
The CAT score can have a very different impact depending on the IIM you are targeting. According to the attached data, IIM Ahmedabad and IIM Bangalore give 25% weightage to CAT, while IIM Calcutta and IIM Lucknow give 30%.
At the other end of the spectrum, IIM Ranchi gives CAT a 65% weightage, while IIM Rohtak and IIM Mumbai give it 60%. This shows why candidates should check the individual admission policy of every IIM instead of assuming that CAT carries the same importance everywhere.

CAT Score Weightage in IIMs 2026: Conclusion
CAT Weightage in IIMs 2026 differs significantly across institutes and even between the pre-PI and post-PI stages. While some IIMs rely heavily on CAT scores during shortlisting, others reduce the CAT component during final selection and give greater importance to PI, academics, work experience and diversity. Therefore, aspirants should not judge their IIM admission chances based on CAT percentile alone. Check the latest selection criteria of each target IIM and understand how CAT contributes to both shortlisting and final admission. A strong CAT score opens the door, but your complete profile ultimately determines your chances of converting an IIM call.
