Official Eligibility Snapshot
| Eligibility Layer | What Applies |
|---|---|
| IMU 10+2 route | Recognised 10+2 with PCM average of at least 60% and English at least 50% in 10th or 12th. |
| IMU graduate routes | The 2026 prospectus also lists specified B.Sc. and B.E./B.Tech routes with defined subject/marks conditions. Check the exact degree wording before application. |
| Relaxation | The IMU prospectus provides the notified SC/ST relaxation in PCM, not in English, plus a relaxation for eligible island Scheduled Tribe candidates. |
| Institute layer | Board recognition, original documents, residential rules, deadlines and counselling requirements apply. |
| Sponsor layer | A company may require higher PCM/English marks, psychometric testing, interviews or a stricter standard. These are company criteria—not universal DGS rules. |
Detailed Requirements
Age Requirement
For the 2026 academic session, the IMU prospectus uses 1 August 2026 as the age-reference date. Published limits for seagoing UG/DNS routes are male General 25, OBC-NCL 28, SC/ST 30; female General 27, OBC-NCL 30, SC/ST 32. Recheck the selected batch notice.
Medical and Eyesight Checkpoint
Medical fitness must satisfy the Merchant Shipping medical rules in force. Obtain the certificate from a DGS-approved medical examiner. Deck-route eyesight and normal colour-vision standards are stricter; use the 2026 prospectus and medical examiner’s decision, not a sponsor’s social media post.
Entrance Examination
IMU-CET applies for the 2026 DNS admission route. A sponsor may also conduct its own aptitude, PCM/English, psychometric and interview stages. Passing IMU-CET does not itself provide sponsorship.
Sponsorship Checkpoint
Status: Required for affiliated-institute sponsored seats / otherwise batch-specific. Apply only against a named, verifiable company scheme or an officially authorised selection channel. The letter should state the institute, batch, selection conditions, medical requirements, training support, cancellation terms and whether the berth remains subject to performance and vacancy.
Sponsorship should be obtained only through a verifiable shipping company or its officially authorised selection channel. Candidates must verify the company, institute, approval status and sponsorship terms before making any payment.
