Why Documents Matter for IISER IAT 2027 Registration
The IISER IAT 2027 registration form requires you to upload scanned copies of specific documents at the time of application. Your application will be rejected if any document is missing, expired, or uploaded in the wrong format.
IISER IAT is conducted jointly by all seven IISERs for admission to the 5-year BS-MS Dual Degree programme. The admission authority uses your uploaded documents to verify your identity, academic eligibility, and category status. Any mismatch between your application data and your documents can lead to disqualification at any stage of the admission process.
IISER IAT 2027 registration is expected to open in April 2027. Keep all your documents scanned and saved in the correct format well before the registration window opens. This approach saves time and reduces errors during form filling. Students who prepare documents in advance are less likely to make mistakes under deadline pressure.
There are three admission channels for IISER IAT 2027: the IAT channel, the JEE Advanced channel, and the SCB (State and Central Board) channel. Your channel choice determines which additional documents you need beyond the standard set. Read all sections of this checklist carefully before you begin registration.

Category-Wise Documents for IISER IAT 2027
If you belong to a reserved category, you must upload your certificate during registration. Failure to upload a valid category certificate at the time of registration may result in loss of all reservation benefits.
| Category | Certificate Required | Issuing Authority |
|---|---|---|
| OBC-NCL (Other Backward Class, Non-Creamy Layer) | OBC-NCL certificate in the Central Government format; must be current and within its validity period (usually one year from issue date) | Sub-Divisional Officer, Tehsildar, or equivalent authority notified by the State Government |
| SC (Scheduled Caste) | Scheduled Caste certificate; no expiry date, but the caste must be in the official Central or State list | Sub-Divisional Officer, District Magistrate, or equivalent |
| ST (Scheduled Tribe) | Scheduled Tribe certificate; no expiry date, but the tribe must be in the official list for your state | Sub-Divisional Officer, District Magistrate, or equivalent |
| EWS (Economically Weaker Section) | EWS income and asset certificate in the prescribed Central Government format; valid for the financial year of application (2026-27) | Tehsildar, Sub-Divisional Officer, or equivalent revenue authority |
| PwD (Person with Disability) | Disability certificate specifying type and percentage of disability; minimum 40% disability required for reservation benefits | Government medical board or district hospital authority |
| General / Unreserved | No category certificate required | Not applicable |
OBC-NCL students must note that a certificate issued only for state-level reservations is not valid for IISER IAT. The certificate must follow the format prescribed by the Central Government. If you are unsure about your certificate’s validity, contact the issuing authority before the registration window opens.
Channel-Specific Additional Documents for IISER IAT 2027
IISER IAT 2027 offers admission through three channels. The documents you need beyond the standard set depend on your admission channel. Study the table below carefully to avoid uploading the wrong document.
| Channel | Additional Document Required | Important Note |
|---|---|---|
| IAT Channel | No additional document required at registration; your admit card is generated after successful registration | You must appear in and qualify IISER IAT 2027 to be considered for admission through this channel |
| JEE Advanced Channel | JEE Advanced 2027 rank card or scorecard issued by the conducting IIT | Only students with a valid JEE Advanced 2027 rank are eligible; a rank from a previous year is not accepted |
| SCB Channel (State or Central Board) | Board rank certificate from your board authority confirming you are in the top 1% of PCM or PCB students in your board’s Class 12, 2027 results | The certificate must be issued officially by your board; a school-issued rank letter or principal’s declaration is not accepted |
Students applying through the JEE Advanced channel must ensure their JEE Advanced 2027 result is declared before the IISER IAT registration deadline. Plan your application timeline accordingly so you have the rank card ready when the IISER IAT form opens.
For the SCB channel, note that boards issue rank certificates at different times and through different processes. Contact your board’s official examination authority after your Class 12 result to understand how to obtain the rank certificate in time for IISER IAT registration.

Photograph Specifications
| Parameter | Specification |

- Before uploading, scan all your documents and save them in the correct file format (JPG or JPEG for photo and signature; check field-specific format for certificates).

Common Document Mistakes and How to Avoid Them
Many students make avoidable errors while uploading documents for IISER IAT registration. Even a single incorrect or invalid document can delay your application or lead to outright rejection. Study each mistake below and check your documents against each point before submitting.
- Uploading an outdated OBC-NCL certificate: Your OBC-NCL certificate must be in the Central Government format and within its validity period. Do not use a certificate issued only for state reservations or one that expired before the application date.
- Photo on a coloured or patterned background: Only plain white or light backgrounds are accepted. Studio photographs with gradient or printed backgrounds will be rejected during scrutiny.
- Signature in block letters or initials only: Your signature must be a handwritten cursive or stylised mark. Printing your name in capital letters or uploading initials is not valid.
- File size exceeding the specified limit: If your scanned document exceeds the maximum file size, compress it using a reliable tool. Do not use heavy compression that makes the document unreadable.
- Wrong Class 12 document for appearing students: If you are appearing in Class 12 boards in 2027, upload your Class 12 admit card, not a school certificate or transfer certificate. Upload the final marksheet only after your result is declared.
- Using last year’s JEE Advanced rank for the JEE Advanced channel: Only a JEE Advanced 2027 rank is valid. A rank from a previous year, even a very high one, is not accepted for IISER IAT 2027.
- Submitting a school-issued rank letter for the SCB channel: The board rank certificate must be issued officially by your examination board, not by your school principal or coaching institute.
- Name mismatch across documents: The name on your Class 10 marksheet must match the name you enter in the form. Even minor spelling differences can trigger a flag during document verification. Attach a self-declaration letter if a discrepancy exists.
