IIM Call Criteria: Why Percentile Alone Does Not Get You Shortlisted
A CAT percentile is one input into a composite score, not a threshold you cross. Every IIM builds its own composite from your percentile plus academic record, work experience and diversity factors — and publishes the weightages in an admissions policy document each year.
This is why a 99 percentile candidate can miss calls that a 97 receives. Below is the structure that composite takes, which parts you can still influence, and how to read a policy document so you are targeting schools that actually suit your profile.
Percentile is one of five, not the whole thing
CAT percentile, class 10 marks, class 12 marks, graduation marks and work experience — with gender and academic diversity often layered on top. Two of those are fixed by the time you read this. Knowing which changes what you should optimise.
Quick Answer (30-Second Read)
How calls work
Composite score, not a cut-off
Each IIM sets its own weights
Two gates, not one
Sectional minimums first
Then the composite ranking
- Sectional percentile minimums are a hard gate. Fail one and your overall percentile becomes irrelevant.
- Class 10 and 12 marks carry weight at several institutes, and they cannot be changed now.
- Academic diversity favours non-engineers at many schools, because the applicant pool skews heavily engineering.
- Work experience is usually banded, with a sweet spot rather than "more is better".
- Read the policy PDF, not a cut-off list. The weightages are published; the cut-off lists are inference.
Each IIM publishes its own admissions policy. Start from iimcat.ac.in and follow through to the individual institute sites.

Sectional minimums are the first gate, so a lopsided profile fails before the composite is even calculated. Sectional percentiles tell you whether you would clear it.
There are two gates, and candidates only plan for one
Shortlisting happens in two stages, and they behave completely differently. The first is a pass-or-fail filter. The second is a ranking.
| Gate 1 — sectional minimums | Gate 2 — composite ranking | |
|---|---|---|
| How it works | Binary. You clear each section's floor or you do not | Continuous. You are ranked against everyone who cleared gate 1 |
| What matters | Your weakest sectional percentile | Your overall percentile plus academics, work ex, diversity |
| Can a strength compensate? | No | Partially — that is what weightages do |
| Typical failure | 99 overall, one section in the 70s | Strong percentile, weak class 10 and 12 record |
Almost all candidate attention goes to gate 2, and almost all avoidable rejections happen at gate 1. A composite score is never calculated for a candidate who failed a sectional minimum — the application is out before academics or work experience are considered at all.
This is the argument for balance, stated institutionally
Every piece of advice telling you to fix your weakest section traces back to gate 1. It is not a general principle about being well-rounded. It is that a single sectional percentile below an institute's floor removes you from consideration entirely, regardless of how good everything else is.
What goes into the composite
The specific weightages differ by institute and change year to year, so what follows is the structure rather than the numbers. Get the numbers from the policy document itself.
| Component | What it measures | Notes |
|---|---|---|
| CAT percentile | Overall, and sometimes sectional, scaled percentile | Usually the largest single weight, but rarely a majority |
| Class 10 marks | Board exam percentage | Often normalised by board. Fixed — you cannot change it |
| Class 12 marks | Board exam percentage | Same. Frequently weighted alongside class 10 |
| Graduation marks | Degree aggregate | Sometimes normalised by stream, which matters for engineers |
| Work experience | Months of full-time post-degree work | Usually banded, with a peak — not linear |
| Gender diversity | Points for under-represented gender | Applied by many institutes |
| Academic diversity | Points for non-engineering backgrounds | Because the pool skews heavily engineering |
The work-experience row is the one most often misread. Weightage is typically banded rather than linear, with a range that scores highest and diminishing or flat returns beyond it. More experience is not automatically better, and someone with a decade of work can score no higher on that component than someone with two or three years.
Would your weakest section clear gate 1?
The composite never gets calculated if a sectional minimum fails. Your sectional percentiles are the number to watch, not the overall.
- Sectional percentiles
- Overall estimate
- Accuracy by section
What you can still change, and what you cannot
Half the composite is already decided by the time most candidates start preparing. Knowing which half changes where your effort should go.
| Component | Changeable now? | What to do about it |
|---|---|---|
| CAT percentile | Yes | This is where your effort belongs. It is also usually the heaviest weight |
| Sectional percentiles | Yes | Fix the weakest. Gate 1 makes this non-negotiable |
| Class 10 and 12 | No | Target institutes that weight them less, and stop worrying about it |
| Graduation marks | Rarely | Final-year candidates can still influence the aggregate |
| Work experience | Slowly | Relevant if you are deciding between attempting now or next cycle |
| Diversity factors | No | Read them to calibrate expectations, not to act on |
The third row deserves emphasis because it causes a lot of unproductive anxiety. If your class 10 and 12 marks are weak, no amount of worry changes them. What you can do is build a target list weighted toward institutes that de-emphasise school academics — and those exist, with the weightages stated openly in their policy documents.
Diversity factors, explained honestly
Two kinds of diversity weighting are common, and both exist for the same structural reason: the applicant pool is heavily skewed.
Academic diversity awards points to candidates from non-engineering backgrounds. The engineering share of CAT applicants is large enough that without such a weighting, cohorts would be close to homogeneous. In practice this means an arts or commerce graduate frequently needs a lower percentile than an engineer for the same call at the same institute.
Gender diversity works similarly, awarding points to the under-represented gender in the applicant pool.
| If you are… | What this means practically |
|---|---|
| A male engineer | The most represented group. Expect to need a higher percentile than the headline figures suggest |
| A non-engineering graduate | Academic diversity points apply at many institutes. Check which ones weight it heavily |
| A woman candidate | Gender diversity points apply widely. Confirm per institute rather than assuming |
| Both non-engineer and under-represented gender | Both weightings can apply, which materially changes your target list |
None of this is a reason to feel either entitled or discouraged. It is a reason to build your target list from actual policy documents rather than from a friend's experience, because two candidates with identical percentiles and different profiles genuinely face different thresholds.
How to read an admissions policy document
Each IIM publishes one, usually as a PDF, usually before or around the CAT registration window. It is the only authoritative source, and it takes about twenty minutes to read properly.
| What to look for | Why it matters |
|---|---|
| Minimum sectional percentiles by category | Gate 1. If you would fail this, nothing else on the page applies to you |
| Minimum overall percentile by category | The second hard floor |
| The weightage table for the shortlist stage | Tells you whether your profile suits this institute at all |
| Whether class 10/12 are normalised by board | Changes how a state-board record compares to a CBSE one |
| Whether graduation is normalised by stream | Engineering aggregates are often lower; some institutes adjust for it |
| The weightage table for the final stage | Different from the shortlist stage. Interview and WAT usually enter here |
The last row surprises people. Shortlist weightages and final-selection weightages are two separate tables, and CAT percentile typically carries less weight in the second. A candidate who scrapes a call can still convert it strongly, and a candidate with a brilliant percentile can lose ground at the interview stage.
One caution about cut-off lists circulating online: they are inference from past outcomes, not published thresholds. Use them for rough orientation and never for a decision. The policy document is the actual rule.
Key Takeaways
- Calls come from a composite score, not a percentile threshold. Percentile is usually the largest weight but rarely a majority.
- Two gates, not one. Sectional minimums are binary and come first — the composite is never calculated if you fail one.
- Class 10 and 12 marks carry weight and cannot be changed. Target institutes that de-emphasise them instead of worrying.
- Work experience is banded, not linear. Ten years does not necessarily beat three on that component.
- Diversity weightings mean identical percentiles face different thresholds. Build your list from policy documents, not from a friend's outcome.
- Shortlist and final-selection weightages are separate tables. A scraped call can still convert strongly.

How do IIMs shortlist candidates for interview?
Through a two-stage process. First, hard minimums on sectional and overall CAT percentile — fail any one of these and your application ends there, regardless of how strong the rest of your profile is. Candidates who clear those minimums are then ranked on a composite score combining CAT percentile with class 10 and 12 marks, graduation marks, work experience and diversity factors. Each IIM publishes its own weightages annually in an admissions policy document, and they differ meaningfully between institutes.
Is 99 percentile enough for an IIM call?
It makes you competitive but does not guarantee anything, because percentile is one input into a composite rather than a threshold you cross. A 99 percentile candidate with weak class 10 and 12 marks can miss calls that a 97 percentile candidate with a strong academic record receives, at institutes that weight school academics heavily. It also does not help at all if one of your sectional percentiles falls below an institute's minimum, since that filter runs before the composite is calculated.
Do class 10 and 12 marks matter for IIM admission?
At many institutes, yes, and they are frequently weighted alongside your CAT percentile in the shortlisting composite. Several also normalise them by board, which changes how a state-board record compares against a CBSE one. Since these marks cannot be changed now, the useful response is to build a target list weighted toward institutes that de-emphasise school academics — and those exist, with the weightages stated openly in their published policies.
Do IIMs have sectional cut offs?
CAT itself does not publish sectional cut-offs, but most IIMs apply minimum sectional percentiles as part of their own criteria. This is a binary filter rather than a weighting — a candidate at 99 overall with one section in the seventies is removed from consideration before their composite is even calculated. It is the institutional reason behind all the advice to fix your weakest section, and it is why a balanced profile outperforms a lopsided one with a higher total.
How much does work experience help for IIM calls?
It carries weight at most institutes, but usually in bands rather than linearly, with a range that scores highest and flat or diminishing returns beyond it. More experience is therefore not automatically better — a candidate with a decade of work can score no higher on that component than someone with two or three years. Freshers are not excluded, and some institutes weight experience lightly. Check the specific bands in each institute's policy rather than assuming a general rule.
Do non-engineers have an advantage in IIM admissions?
At many institutes, yes, through academic-diversity weightage. The engineering share of the CAT applicant pool is large enough that without such a weighting cohorts would be close to homogeneous, so points are awarded to candidates from other academic backgrounds. In practice this often means a non-engineering graduate needs a somewhat lower percentile than an engineer for the same call at the same school. How much varies considerably, so check each policy rather than relying on a general impression.
Where can I find IIM admission criteria?
Each IIM publishes its own admissions policy, usually as a PDF on its website, typically around the CAT registration window. That document is the only authoritative source and takes about twenty minutes to read properly. Look specifically for the minimum sectional and overall percentiles by category, the shortlist-stage weightage table, whether school marks are normalised by board, and the separate final-selection weightage table. Cut-off lists circulating online are inference from past outcomes, not published thresholds.
Are shortlist criteria the same as final selection criteria?
No, and this surprises many candidates. Institutes publish two separate weightage tables — one governing who gets a call and another governing final selection after the interview and written test. CAT percentile typically carries less weight in the second, with interview performance, written assessment and sometimes work experience weighted more heavily. This means a candidate who scrapes a call can still convert it strongly, and one with an outstanding percentile can lose ground at the final stage.
Can I get an IIM call with low graduation marks?
Possibly, depending on the institute. Graduation marks are one component among several, and some institutes normalise them by stream — which helps engineering candidates, whose aggregates are often structurally lower than those in other disciplines. If your graduation record is weak, compensate by pushing your CAT percentile and by targeting institutes whose published weightage leans toward the exam rather than the academic record. Final-year candidates still have some ability to influence their aggregate.
What percentile do new IIMs require compared to older ones?
Newer IIMs generally shortlist at lower percentiles than the older, more established ones, but the difference is smaller than candidates often assume and varies year to year with applicant numbers. More importantly, the weightage structures also differ — some newer institutes weight the CAT score more heavily and academics less, which can suit a candidate with a strong exam performance and a weaker school record. Read the policies rather than assuming a simple ranking of difficulty.
