Quick Answer

IMU follows Central Government reservation policy: OBC-NCL 27%, SC 15%, ST 7.5%, EWS 10%, General 50.5%. SC/ST get 50% minimum marks eligibility (vs 60% General). EWS is 10% for General category candidates with family income below ₹8 lakh. All categories must appear and pass IMU-CET — reservation only affects cutoff rank and seat allocation.

IMU-CET Reservation 2026: Complete Guide to OBC, SC, ST, EWS Quotas

If you’ve been confused about how reservation works in IMU-CET, you’re not alone. Students on Reddit, in WhatsApp groups, and in coaching centres regularly get this wrong — either overestimating their chances or missing benefits they’re entitled to.

This is the most detailed breakdown of the IMU-CET 2026 reservation system you’ll find outside the official IMU prospectus.

Does IMU Follow Central Government Reservation Policy?

Yes. The Indian Maritime University (IMU) is a Central University established under the IMU Act 2008. As a Central Government institution, it follows the Central Government reservation policy — the same framework applied by IITs, NITs, and other central institutions.

This means:

Reservation rules are defined by Government of India, not by IMU independently
The percentage breakdown is standardized
Benefits apply to all IMU courses (B.Tech, B.Sc, Diploma, PG programs)

IMU-CET 2026 Seat Reservation Breakdown

Category	Reservation %
General (Unreserved)	50.5%
OBC-NCL (Other Backward Classes – Non-Creamy Layer)	27%
SC (Scheduled Caste)	15%
ST (Scheduled Tribe)	7.5%
EWS (Economically Weaker Section)	10%

Important clarification: EWS reservation (10%) was added from 2019 onwards under the 103rd Constitutional Amendment. It is carved in addition to the existing 49.5% reserved seats.

So to directly address the Reddit debate: EWS quota is 10%, SC is 15%, and ST is 7.5%. In a 100-seat intake:

EWS: 10 seats | SC: 15 seats | ST: ~8 seats (7.5 rounded)

EWS has more seats than ST in absolute numbers. This reflects population-based policy intent, not an error.

Category-Wise Relaxations in IMU-CET 2026

1. Academic Eligibility Marks

Category	Minimum PCM % Required
General / EWS	60%
OBC-NCL	55% (some courses)
SC / ST	50%

SC/ST students with 50-59% in PCM who wouldn’t be eligible under General criteria CAN apply.

2. Age Relaxation

SC/ST candidates: 5 years over General upper age limit
OBC-NCL candidates: 3 years relaxation
EWS candidates: No age relaxation (EWS is purely economic)

The standard upper age limit for most IMU courses is 25 years. So SC/ST can join up to 30, OBC-NCL up to 28.

3. Application Fee

SC/ST/PwD candidates receive a reduced application fee. Check the current prospectus for the exact amount.

EWS Certificate for IMU-CET — What You Need

EWS is for General category candidates whose family income is below ₹8 lakh per annum and who do not own agricultural land beyond specified limits.

Key requirements:

Must belong to General category (SC/ST/OBC cannot claim EWS)
Annual family income below ₹8 lakh
EWS certificate from Tehsildar/SDM/District Magistrate
Certificate must be for the correct financial year specified in the IMU-CET notification
Validity: typically one financial year only

Common mistake: Many students get EWS certificates for the wrong year. Check the exact year requirement when the notification is released.

OBC-NCL: The Non-Creamy Layer Condition

The OBC reservation at IMU applies only to OBC-NCL — Non-Creamy Layer.

Creamy Layer limit: Family income above ₹8 lakh per annum.

Income ₹8 lakh+: You’re treated as General category
You need a valid OBC-NCL certificate, not just an OBC certificate

State vs Central OBC lists: For IMU, only the Central OBC list is applicable. Verify at the National Commission for Backward Classes (NCBC) website that your caste is on the Central list — not just the state list.

SC/ST Documents Required

Caste certificate issued by competent authority (DM, SDM, Tehsildar)
Certificate in the prescribed Central Government format
Authority must have jurisdiction over your home district

State certificates in state-specific formats may sometimes be questioned. If you’ve had issues, get the certificate reissued in Central Government format by the District Magistrate.

How IMU-CET Cutoffs Work for Reserved Categories

Every year, IMU publishes category-wise cutoff ranks for each course and campus.

Illustrative example: For B.Sc Nautical Science at IMU Chennai:

General cutoff: ~rank 350 | OBC-NCL: ~rank 800 | SC: ~rank 1,500 | ST: ~rank 2,000 | EWS: ~rank 500

A student with rank 600 who is General might not get Chennai. But if they’re OBC-NCL, they qualify. Always apply for all campuses and check category-wise cutoffs after results.

PwD (Persons With Disabilities) — Horizontal Reservation

In addition to vertical reservation (the categories above), IMU provides horizontal 5% reservation for PwD candidates across all categories.

For PwD:

Minimum 40% disability required
Disability certificate from a Government hospital
Specific disability benchmarks apply

Critical note for maritime: Even if you qualify academically under PwD reservation, seafaring requires ENG1 medical fitness. Some disabilities may affect your ability to serve at sea. Verify medical eligibility before applying.

Common Myths About IMU-CET Reservation

Myth 1: “Reserved category students don’t have to clear the exam.” False. Every candidate regardless of category must appear and pass IMU-CET. Reservation affects cutoff rank and seat allocation — not exam exemption.

Myth 2: “My state OBC certificate works for IMU.” Only Central OBC list applies. Check if your caste is on the Central list.

Myth 3: “Reserved category students take jobs away from deserving candidates.” This is not an eligibility question. Every student who uses reservation still has to pass the same training, exams, and maritime standards at sea.

How to Claim Your Category at Application Stage

Select your category correctly in the IMU-CET application
Upload required certificate (clear scan of original)
Do NOT claim a category you’re not entitled to — discovered fraud leads to admission cancellation

If unsure whether you qualify, consult your district administration before applying.

Conclusion

The IMU-CET reservation system follows standard Central Government rules. Know your category, get the right documents, and use every benefit you’re entitled to. The reservation isn’t a shortcut — you still have to clear the exam and complete the same training. But it can make the difference between getting the seat you want and not.

Don’t leave category benefits on the table.
