If you are an Indian applicant sitting on a decent CAT percentile, a half-prepared GMAT plan, and a GRE score you took last year for a US masters application, the three-test question is quietly the highest-leverage decision in your entire ISB application. This post is for the working professional in Bengaluru, Mumbai, or Gurugram who has to pick one test in the next thirty days and cannot afford to pick wrong.
What ISB actually accepts, programme by programme
ISB's flagship one-year MBA, the PGP, accepts GMAT (Focus or Classic) and GRE. Both must be the test-centre version. Online and at-home formats are not accepted, per the ISB PGP eligibility page. The PGP does not accept CAT. Full stop. If a coaching counsellor told you otherwise, they were quoting the PGP YL rules and mixing the programmes up.
ISB's PGP Young Leaders programme, the PGP YL for final-year students and early-career applicants, accepts GMAT and CAT, per the ISB PGP YL page. PGP YL is the only ISB route where a CAT score gets you through the door.
The takeaway that costs Indian applicants their application: PGP does not accept CAT. If you are a working professional applying to the flagship one-year MBA, your CAT preparation is not a hedge. It is a distraction unless you are also applying to IIM Ahmedabad, Bangalore, or Calcutta in the same cycle.
The 2026 medians, from the official class profile
For the ISB PGP Class of 2026, the admitted GMAT Focus Edition average sits at 669 with a reported admitted range of 555 to 765, per CrackVerbal's ISB 2026 profile deep-dive. The GMAT Classic average for the same class is 720, admitted range 640 to 780. Average GRE score is 327, admitted range 306 to 336.
Two things Indian applicants misread here. First, the Focus median of 669 is not a lower bar than the Classic 720. The concordance is not linear. A 720 Classic maps roughly to a 665 Focus, so the Focus 669 is functionally the same as the old 720 benchmark most consultants still quote. Second, the range starts at 555 Focus and 306 GRE, but the applicants at that end were not average profiles. They had unusually strong work experience, leadership, or IP achievements. If your profile is a standard IT services engineer with three to five years of experience, plan for 685 Focus or higher, not 555.
If you are an IT services engineer targeting PGP
You are the median ISB applicant. Roughly 54 percent of ISB PGP applicants come from engineering backgrounds, per the IMS India ISB 2026 admissions guide. Every point above the median matters more for your profile than it does for a CA or a defence officer. Take the GMAT Focus. It is the test the largest fraction of ISB applicants submit, which means the adcom has a well-calibrated benchmark for what your score signals about you. Target 705 Focus (equivalent to about a 750 Classic). GRE is technically accepted, but for the crowded IT services engineer pool the GMAT reads more legibly to the ISB adcom.
If you are a CA, CFA, or non-engineer targeting PGP
Your quantitative signal is already documented in your professional credential. A GRE at 325+ works for you, and the verbal-heavy structure often plays to a CA's strengths. If you have taken the GRE for a US masters application in the last five years and scored well, do not retake the GMAT unless the score is under 320. ISB accepts scores valid for five years from the test date, per the ISB PGP application deadlines and rules page. Save the six weeks of prep for essays and interviews.
If you are a final-year student or early-career applicant eyeing PGP YL
CAT becomes a real option for you here, and often the smarter one. PGP YL admits at CAT 98 to 99+ percentiles based on prior-year trends. If you are already grinding for CAT with an IIM ABC target, your PGP YL application costs you nothing extra on the test front. If your CAT prep is patchy but your quant is strong, the GMAT Focus at 685+ is the safer play. Do not attempt both in the same year unless you have already scored 685+ on a GMAT mock.
If you are a reapplicant with a valid old score
Your old GMAT is valid for five years from the test date. If you scored 720 Classic three years ago, that is a 665 Focus equivalent and lands you at the median. Do not retake unless the score is below 690 Classic (equivalent to about 635 Focus). Adcoms read a retaken score as insecurity if the improvement is under 30 Focus points. The application benefits more from your essay revision and a sharper career-goal narrative than from a 15-point score increase.
The one detail everyone misses: unofficial scores at the deadline
ISB accepts unofficial GMAT or GRE scores at the round deadline if the test has been taken on or before the deadline date, per the ISB PGP eligibility page. This is the escape valve for the working professional who cannot get a February test slot booked before the Round 1 deadline. Book the earliest test date, submit the unofficial score at deadline, and follow up with the official within the window ISB specifies in the application portal.
What this means for Indian applicants
The test is a scoring signal, not a filter. ISB does not publish a cutoff, and every year admits arrive at the lower end of the reported range because their profile carried the extra weight. But the median exists because it works. If your profile is average-to-strong for the Indian applicant pool, plan to submit at or above the median. If your profile is a standout on some dimension (early GM, a founded company, an IIT plus a global research paper), the test threshold relaxes.
Two decisions matter more than which test you pick. First, whether the score you eventually submit is competitive for your specific profile bucket. That is what a profile evaluation is built to answer. Second, whether the rest of your application (essays, recommendation letters, interview) uses the runway your score buys you. The full application walkthrough is on our ISB PGP admissions guide, which covers deadlines, essay strategy, and round selection in one place.
Common questions Indian applicants are asking
Does ISB accept CAT for the PGP? No. CAT is only accepted for the PGP YL programme for final-year students and early-career applicants. The flagship one-year PGP accepts GMAT (Focus or Classic) and GRE only.
Should I take GMAT Focus or GMAT Classic? Take the Focus. As of 2026, the Classic is being phased out, and the Focus is the standard test format. All the ISB Class of 2026 admits at 555 to 765 are Focus scores.
Is a 685 GMAT Focus enough for ISB? For the median IT services engineer profile, 685 sits below the class average of 669 but within the admitted range. It is enough to get read seriously if the rest of the profile is strong. For a distinctive profile (non-engineer, founder, standout international experience), 685 is comfortably safe.
Can I submit a GRE score I took two years ago? Yes, if it is within the five-year validity window ISB specifies. Do not retake unless your score is below the 320 mark.
How much does the GMAT vs GRE choice change my admit odds at ISB? Marginally. ISB reads both scores against internal benchmarks calibrated for its applicant pool. What changes your odds is your profile-test fit: whether the test you took gives the adcom a clean read on your strongest signal.
