IIM Shillong Selection Criteria 2026 — CAT Sectional Cutoffs, Composite Score & the PI-Based Final Merit List Explained
The IIM Shillong selection criteria for PGP 2026–28 are among the most diversity-driven and profile-focused of any IIM. Strict sectional cutoffs, a composite that blends CAT with a normalized rating score, shortlisting done within six academic-discipline groups, and a work-experience curve that peaks at just 18–24 months — here is the complete two-phase process, decoded.

1. What Makes the IIM Shillong Selection Criteria Different
IIM Shillong is the only IIM in the North-East, and its admissions reflect a clear identity built around sustainability, ethics and diversity. That philosophy shows up directly in the IIM Shillong selection criteria: rather than ranking everyone on one big list, the institute deliberately groups candidates by academic discipline so that an arts or commerce graduate isn’t competing head-to-head with engineers for a call.
The process runs in two phases — a shortlist for the Personal Interview, then a final merit list — and the weightings shift meaningfully between them.
Table 1 — IIM Shillong Admission: The Two Phases
| Phase | What Happens | What Decides It |
|---|---|---|
| Phase 1 | Shortlist for the Personal Interview | Composite Score (65% CAT + 35% NARS), then discipline, category & gender grouping |
| Phase 2 | Final merit list & admission offers | CAT 40 + PI 40 + ARS 10 + Gender Diversity 10 |
2. Phase 1, Step 1: CAT Sectional Cutoffs You Must Clear
The first gate is purely about CAT, and IIM Shillong is unusual in how it screens — it publishes strict sectional percentiles rather than leaning on an overall figure. You must clear the minimum in every section to stay in the process.
Table 2 — IIM Shillong CAT Sectional Minimum Percentiles
| Category | VARC | DILR | QA |
|---|---|---|---|
| General | 75 | 75 | 75 |
| EWS | 75 | 75 | 75 |
| SC | 60 | 60 | 60 |
| ST | 50 | 50 | 50 |
| DA (PwD) | 50 | 50 | 50 |
⚠ A Weak Section Ends Your Application Here
Because IIM Shillong screens section by section, a brilliant overall percentile cannot rescue one weak area. A General candidate at the 99th percentile overall but 72 in QA is out. Balanced sectional preparation isn’t optional here — it is the price of entry.
3. Phase 1 of the IIM Shillong Selection Criteria: Composite Score & ARS
Candidates who clear the sectional gate are ranked on a composite score. This is the core of the IIM Shillong selection criteria, and it weighs CAT heavily while still rewarding a consistent profile.
Table 3 — Phase-1 Composite Score Weightage
| Component | Weightage |
|---|---|
| CAT 2025 Overall Percentile | 65% |
| Normalized Application Rating Score (NARS) | 35% |
The NARS comes from your Application Rating Score (ARS), which adds up four components: Class 10 (A), Class 12 (B), Graduation (C) and Work Experience (D). Your academics are converted to points on fixed slabs.
Table 4 — Academic Rating Scores (A, B, C)
| Percentage | Class 10 (A) | Class 12 (B) | Graduation (C) |
|---|---|---|---|
| 95–100 | 10 | 10 | 10 |
| 90–94.99 | 9 | 9 | 9 |
| 85–89.99 | 8 | 8 | 8 |
| 80–84.99 | 5 | 5 | 6 |
| 75–79.99 | 2 | 2 | 4 |
| 70–74.99 | 0 | 0 | 2 |
| Below 70 | 0 | 0 | 0 |
Work experience (D) is scored on a curve that rises fast, peaks early, and then falls away — IIM Shillong clearly prefers early-to-mid-career applicants.
Table 5 — Work Experience Scoring (D)
| Work Experience | Score |
|---|---|
| Below 7 months | 0 |
| 7–12 months | 6 |
| 12–18 months | 12 |
| 18–24 months | 14 (maximum) |
| 24–30 months | 10 |
| 30–36 months | 6 |
| 36–42 months | 2 |
| 42+ months | 0 |
💡 The 18–24 Month Sweet Spot
Your ARS is A + B + C + D, and the NARS divides your ARS by the average of the top 50 ARS in the applicant pool. The standout feature is work experience: it peaks at 14 points for 18–24 months and then drops steadily to zero beyond 42 months. No other top IIM penalises long tenures this sharply. If you have around two years of experience, the IIM Shillong selection criteria reward you more than almost anywhere else.
4. Academic Diversity & Gender: How IIM Shillong Groups Candidates
Here is where IIM Shillong genuinely stands apart. Instead of one combined merit list, candidates are sorted into six academic categories and shortlisted proportionally from each — so you compete largely against people from your own academic background.
- AC1: Medicine & Surgery
- AC2: CA, CS, CMA, Actuarial
- AC3: Commerce, Economics, Management
- AC4: Engineering, Technology, Science
- AC5: Arts, Humanities, Law, Design, Education
- AC6: Any other disciplines
The share of PI calls from each discipline is set in proportion to how many applicants come from that discipline. After the academic grouping, candidates are further sub-grouped by social category (General, EWS, SC, ST, OT) and then by gender, and ranked on composite score within each micro-group. The top candidates in each get the interview call.
💡 You Compete Within Your Discipline, Not Against Engineers
For non-engineering aspirants — commerce graduates, CAs, doctors, lawyers, artists — this is a real structural advantage. The proportional, discipline-wise shortlist means your profile is judged against peers from the same background, not against a flood of engineering applicants. Diversity isn’t a bonus point at IIM Shillong; it is built into the architecture of the shortlist.
5. Phase 2 of the IIM Shillong Selection Criteria: PI & Final Merit List
Shortlisted candidates attend the Personal Interview, where communication skills are assessed but — notably — not counted in the final score. You do, however, have to clear minimum PI cut-offs to remain in contention.
Table 6 — Minimum PI Cut-offs
| Category | Communication | PI |
|---|---|---|
| General / Others | 30% | 30% |
| EWS | 30% | 30% |
| SC | 25% | 25% |
| ST | 20% | 20% |
| DA (PwD) | 20% | 20% |
The final merit list is then built on a fresh 100-point overall score. CAT’s weight drops from 65% to 40%, and the interview rises to match it exactly.
Table 7 — Final Overall Score (Phase 2) Weightage
| Component | Weightage |
|---|---|
| CAT 2025 Score | 40% |
| Personal Interview | 40% |
| Application Rating Score | 10% |
| Gender Diversity | 10% |
💡 CAT and the Interview Carry Equal Weight
At the final stage, CAT (40%) and the PI (40%) are perfectly balanced, with ARS and gender diversity at 10% each. So a strong CAT gets you to the table, but it does not finish the job — your interview can lift or sink you by the same margin. And remember: graduation must be completed by 31 December 2026 for any offer to hold.
6. IIM Shillong Selection Criteria vs the Other IIMs
Set against the older IIMs, IIM Shillong’s framework has a character all its own — discipline-wise shortlisting, an early-career work-ex peak, and a final where CAT and PI weigh the same.
Table 8 — IIM Shillong vs Calcutta vs Bangalore vs Ahmedabad
| Parameter | IIM Shillong | IIM Calcutta | IIM Bangalore | IIM Ahmedabad |
|---|---|---|---|---|
| Shortlist — CAT | 65% | ~66% | 55% | ~65% |
| Shortlist — profile (NARS/academics) | 35% (X+XII+grad+work-ex) | ~29% (X+XII) | 30% (X+XII+grad) | In rating |
| Academic diversity | 6 ACs, proportional shortlist | Scored at final (6%) | — | Academic category |
| Work-ex sweet spot | 18–24 months (0 past 42) | 24–36 months | caps at 36 months | In rating |
| Final — Personal Interview | 40% | 48% | 40% | 50% |
| Final — CAT | 40% | 30% | 25% | 25% |
💡 Which Profile Fits IIM Shillong?
If you have balanced CAT sections, consistent academics, around two years of work experience and a non-traditional academic background, the IIM Shillong selection criteria are unusually friendly — the discipline-wise shortlist and the early work-ex peak both work in your favour. If your strength is sheer CAT firepower with a heavy academic record, a school like IIM Bangalore may reward that mix more. Across all of them, balanced sectional excellence with a 99+ overall keeps every door open.
7. What a Strong IIM Shillong Profile Looks Like in 2026
Pulling the rules together, here is the profile that converts an IIM Shillong call:
- CAT: strong and genuinely balanced: You must clear every sectional cut-off (75 each for General), and CAT is 65% of the shortlist — so no weak section, and aim for a 95–99+ overall to be competitive after the composite.
- Consistent academics across 10th, 12th and graduation: 95%+ banks the full 10 rating points in each; strong, steady marks lift your ARS and therefore your NARS.
- Around two years of work experience: 18–24 months is the 14-point peak. There is a real penalty for waiting too long — beyond 42 months, work experience scores zero.
- A non-traditional academic background is an asset: Because shortlisting is proportional within six discipline groups, commerce, CA, medicine, law and arts profiles compete within their own pool. Akshita — a Quantifiers non-engineer who tamed the dreaded QA to a 98.95%ile — is exactly the kind of profile this structure rewards.
- Female candidates gain at multiple stages: Gender sub-grouping shapes the shortlist, and gender diversity is 10% of the final score.
- Interview readiness is decisive: The PI is 40% of the final score and you must clear the PI and communication cut-offs. Quantifiers’ GDPI preparation covers PI storytelling, communication and current affairs, included with enrolled courses.
This is the balanced, well-rounded profile Quantifiers builds students toward every year. Mridul (99.98%ile), Pallav (99.98%ile), Nikhil (99.96%ile) and Akshita (98.95%ile, a non-engineer who conquered QA) show that the right plan beats the right background.
