  • Program Duration & Audience:

    • ISB offers a 1-year PGP (MBA equivalent) designed for candidates with 4–8 years of work experience.

    • IIMs offer a 2-year PGP (MBA equivalent), typically admitting candidates with 0–3 years of experience.

Bottom Line:

  • Choose ISB if you are a mid-career professional looking for a fast-track MBA with global exposure.

Choose IIM if you are early in your career and want strong domestic brand equity with a 2-year immersive experience.



  1. Why is ISB ranked higher than IIM?

ISB is often ranked higher than IIMs in global MBA rankings because its 1-year PGP is internationally recognized as a full-time MBA, with strong research output, global faculty, higher average GMAT scores, and international student mix compared to IIMs’ 2-year PGDM programs.


When comparing rankings of ISB vs IIMs, it’s important to note that:

1. Type of Program

  • ISB PGP (1 year) is classified globally as an MBA equivalent.

  • Most IIM flagship programs are PGDM (2 years), not always considered MBAs abroad.

  • Only IIMs with EQUIS/AMBA/AACSB accreditations and 1-year executive MBAs (like IIM Ahmedabad PGPX, IIM Bangalore EPGP, IIM Calcutta MBAEx) are ranked alongside ISB internationally.

2. Global Rankings (FT 2024 MBA Rankings)

  • ISB PGP: Ranked 31st worldwide.

  • IIM Ahmedabad PGPX: Ranked 41st worldwide.

  • IIM Bangalore EPGP: Ranked 47th worldwide.

  • IIM Calcutta MBAEx: Ranked 67th worldwide.

3. Why ISB Scores Higher

  • GMAT Scores: ISB average GMAT ≈ 710–730, among the highest in Asia.

  • Faculty & Research: ISB emphasizes global research publications and attracts international visiting faculty.

  • Alumni Outcomes: ISB graduates see faster career acceleration and stronger salary growth metrics, which heavily influence FT rankings.

  • Global Appeal: ISB has a more diverse, international applicant pool compared to IIMs.

4. India Rankings

  • In NIRF India Rankings, IIMs (Ahmedabad, Bangalore, Calcutta) usually rank above ISB because NIRF emphasizes public institution legacy, government recognition, and long-term academic reputation.


Bottom Line:


 ISB ranks higher than IIMs in global MBA rankings due to its 1-year MBA-equivalent program, international recognition, high GMAT averages, and stronger research/alumni outcomes, while IIMs dominate Indian rankings due to their legacy and government recognition.

The top 5 IIMs in India (NIRF 2024 rankings) are IIM Ahmedabad, IIM Bangalore, IIM Kozhikode, IIM Calcutta, and IIM Lucknow.


The Indian Institutes of Management (IIMs) are ranked annually by NIRF (National Institutional Ranking Framework) and global bodies like Financial Times. Based on NIRF 2024 (the most authoritative Indian ranking system), the top five are:

  • The QS Global MBA Rankings 2025 offer a differing hierarchy, positioning IIM Bangalore as the top Indian business school, followed by IIM Ahmedabad in 2nd place.

  1. Is 74 a good score in CAT?

A 74 percentile in CAT is considered low and is generally not sufficient for admission to top IIMs; it may only qualify for newer or Tier-3 MBA colleges.


The Common Admission Test (CAT) is used primarily by the IIMs and other top B-schools in India, not ISB (which accepts GMAT/GRE only).

CAT 74 Percentile – What It Means

  • Top IIMs (Ahmedabad, Bangalore, Calcutta, etc.): Require 98–99 percentile for General category.

  • Mid-tier IIMs (Trichy, Ranchi, Udaipur, etc.): Typically need 90+ percentile.

  • Newer IIMs and Tier-2 institutes: May consider 80–85 percentile cutoffs.


74 percentile: Usually too low for IIMs, but may still get calls from Tier-3 B-schools and private universities that accept CAT.



  1. Does ISB accept CAT scores for admission? 

It depends—for the flagship 1-year PGP, ISB accepts only GMAT or GRE; however, for the newer PGP-YL (Young Leaders) program and the Fellow Program in Management (FPM), ISB does accept CAT as well.


Official ISB Admissions Policy

  • For the 1‑Year Post Graduate Program in Management (PGP), which requires 24+ months of work experience, ISB mandates submission of a GMAT or GRE score and does not accept CAT scores.

  • For the PGP‑YL (Young Leaders) program, designed for candidates with 0–2 years of work experience, ISB does accept CAT scores, along with GMAT and GRE. ISB obtains CAT scores directly from the testing authority when provided.

  • For the Fellow Program in Management (FPM), ISB also accepts CAT, besides GMAT, GRE, or JRF.

PGP-YL (Young Leaders)

FPM (Fellow Program)

Why This Matters

  • Flagship PGP: ISB targets professionals seeking a one-year MBA equivalent; hence, it sticks to globally recognized standards like GMAT/GRE.

  • PGP-YL: Offers access to early-career candidates (including fresh grads), thus adding flexibility by accepting CAT.

  • FPM: As a research-oriented track, it aligns with other academic assessments like CAT or JRF.



  1. Is ISB as good as IIM?

Yes, ISB is considered as good as the top IIMs (Ahmedabad, Bangalore, Calcutta), with ISB ranked 27 globally (FT 2025), making it India’s highest-ranked MBA program internationally.


The comparison between ISB and IIMs depends on factors like program format, global exposure, and career outcomes. While both are Tier 1 business schools in India, they serve slightly different student segments.

  • IIMs (A/B/C): 2-year MBA (PGP) program; admits students largely with 0–3 years’ experience.

3. Admissions

  • ISB: Requires GMAT/GRE, 2+ years of work experience, holistic profile review.

  • IIMs: Primarily CAT exam; admits younger students (many freshers).

4. Placements & Packages

  • ISB (Class of 2023): Average package ₹34.2 LPA.

  • IIM A/B/C (2023): Averages in the ₹30–34 LPA range, comparable to ISB.
