In fact, the institute has done better than IIM Ahmedabad on various parameters including Graduation Outcomes (GO) and a perfect 100 out of 100 Perception score.
The gap of 1.74 points which resulted in a rank drop of IIM Bangalore is because of Research & Professional Practice (RP) scores. This has become a single structural battlefield as National Institutional Ranking Framework, NIRF, gives 30% of weightage to this parameter.

Where Does IIM Bangalore Win & Where Does It Fall
IIM Ahmedabad ranked one for six consecutive years. IIM Bangalore received a perfect PR score but even then missed the number 1 spot. Various factors have contributed to the ranking changes over the decade.
IIM Ahmedabad maintains a 2.41 point lead in Teaching, Learning & Resources (TLR) because of Student Strength (SS) and Financial Resources Utilization (FRU). The weightage of TLR parameters is 30% and adds another +0.804 composite points to IIM Ahmedabad’s tally. The TLR score of IIM Ahmedabad stood at 91.84 while for IIM Bangalore, TLR score was 89.43 in NIRF 2025 rankings.
IIM Bangalore leads IIM Ahmedabad in both Graduation Outcomes (GO) (98.86 vs 98.72) and Outreach & Inclusivity (OI) (73.27 vs 72.01). While these leads show IIM Bangalore’s excellence in student placements, median compensation, and campus diversity, their combined weighted contribution (1.4 points) is too small to alter the order of final rankings.
IIM Bangalore achieved a perfect 100/100 score in Perception (PR) in 2025 rankings, outperforming IIM Ahmedabad by 6.74 points. IIM A got a PR score of 93.26, but, because Perception carries only a 10% weightage, IIM Bangalore’s lead yields just +0.674 composite points. So, this perfect score was not enough to offset IIM A’s combined +2.568 composite point advantage in TLR and RP parameters.
