"What GMAT score do I need for ISB" is one of the most-searched questions among Indian MBA aspirants — and one of the most consistently misunderstood. There's no official cutoff published by ISB or most IIM programs. What exists instead is a range built from admitted-class data, and understanding that range properly matters more than chasing a single magic number.
Here's what the current data actually shows, and how to use it.
ISB GMAT Score Benchmarks (Class of 2026)
A few things worth understanding about this range:
ISB does not enforce a cutoff. The 665–669 figure is a class average, not a floor. Scores across the admitted class have ranged as widely as 555 to 765, which tells you plainly that GMAT score alone doesn't determine outcomes — the rest of the application carries real weight.
A below-average score isn't disqualifying, but it does raise the bar elsewhere. If your score sits meaningfully below 655, your work experience, essays, academic record, and interview performance need to do proportionally more work to make your case. A 645 with a genuinely distinctive profile is not automatically out of contention; a 645 with an otherwise unremarkable application is a harder sell.
Class size hasn't diluted the score bar. ISB's class has grown to over 800 students across its Hyderabad and Mohali campuses in recent years, and the average GMAT score hasn't drifted downward with that growth — a signal that ISB continues selecting on quality even at scale.
ISB also accepts GRE, with an average admitted GRE score of roughly 320–330. If you're weighing which test to take, see our full GMAT vs GRE comparison.
Work experience is a separate, real requirement, independent of your score: a minimum of 24 months of full-time work experience as of March 31 of the application year, with the admitted class averaging around 4 years.
IIM and Other Top Indian B-School GMAT Benchmarks
Unlike ISB's single, well-documented PGP program, "the IIMs" cover several different programs with different GMAT expectations — mainly the executive and one-year programs, since IIMs' flagship two-year PGP programs primarily admit through CAT, not GMAT.
These figures shift year to year and are best treated as directional benchmarks, not fixed cutoffs — always verify current figures directly on each institute's admissions page before finalizing your target score, especially since GMAT Focus Edition figures (on the 205–805 scale) and references to the older classic-GMAT scale (200–800) sometimes get mixed up across sources. If you see a benchmark quoted that looks unusually high, check which scale it's referencing.
How GMAT Focus Edition Scores Compare to Classic GMAT Figures
If you're cross-referencing older benchmark data (much of what's published about IIM and XLRI cutoffs predates the 2024 transition to the Focus Edition), keep in mind the scoring scales are different and not perfectly one-to-one: classic GMAT ran 200–800, while the Focus Edition runs 205–805 with a compressed scoring distribution. A widely cited approximate mapping puts a classic 710–720 in the same competitive tier as a Focus Edition 655–695 — but always use GMAC's official concordance table for anything you're relying on to make a real decision.

Setting Your Own Target Score
Rather than chasing a single generic number, build your target score from your actual shortlist:
- List your target programs and pull their most recently published average GMAT scores directly from each institute's official site
- Aim above the average, not just above any published minimum — the average is a better predictor of a genuinely competitive application than a floor number
- Factor in your own profile strength. If your work experience, academic background, or extracurricular record is unusually strong, you may have more room below the average than a more conventional applicant pool would. If your profile is closer to the median applicant (a common engineering-to-IT-to-consulting trajectory, for instance), aim meaningfully above average to stand out on the score dimension
- Treat 700+ as a reasonable general target if you're applying broadly across top Indian and international programs, then adjust up or down based on your specific shortlist

The Bigger Picture: Score Is One Input, Not the Whole Application
Every current data point on ISB and IIM admissions converges on the same conclusion: score gets you into the competitive conversation, but it doesn't close the decision. Work experience quality (not just years), a clear and specific reason for pursuing an MBA now, strong essays, and interview performance are evaluated alongside — not after — the GMAT score. Treating your score as the single lever to maximize, at the expense of the rest of your application timeline, is a common and avoidable mistake.
A 700 with a generic application loses to a 670 with a sharp, specific story. Both parts need real work.
