CAT Correction Window 2026: Editable Fields and How to Make Corrections

The CAT 2026 application form correction window is a critical, albeit limited, facility provided by IIM Indore for candidates who have successfully completed their registration and fee payment. This window is designed to offer eligible aspirants a final opportunity to rectify certain details in their submitted application that might have been entered incorrectly or uploaded in an unsuitable format. It is imperative to understand that this facility is not an open invitation to overhaul your entire CAT application. Only specific fields, as officially designated by IIM Indore, will be made available for modification through the correction portal on the official CAT website, iimcat.ac.in. Candidates must regularly check the portal around late September 2026 and complete any required changes strictly within the specified correction period. Failing to do so means your application will be processed with the originally submitted details, which could have adverse implications.

Based on the correction facilities provided in previous CAT sessions, IIM Indore is expected to allow candidates to modify a select few, but very important, application details. This limited flexibility underscores the need for precision during initial registration, yet offers a crucial safety net for common mistakes.

Your photograph is a primary identifier, and ensuring it meets all specifications is non-negotiable. Candidates will likely be able to replace their uploaded photograph if the initial image is unclear, incorrectly sized, poorly lit, or does not adhere to the prescribed requirements. A clear, recent photograph is vital for identity verification throughout the examination process, from admit card to interview stages. The new photograph must strictly follow the specifications mentioned by the CAT authorities regarding dimensions, file size, and background.

Alongside the photograph, your signature is another key biometric detail. The signature may also be editable through the correction facility, allowing candidates to upload a fresh image if the previously submitted one is unclear, cropped improperly, or fails to meet the required specifications. An illegible or improperly scanned signature can raise red flags, so ensure your updated signature is clear and correctly proportioned.

Test city preferences are practical choices that impact your examination logistics. Candidates may also get the option to modify their preferred test city choices from the options available on the CAT application portal. This flexibility is particularly useful if your circumstances change after initial registration, such as a relocation. While the option to change preferences exists, candidates should remember that the final allocation of test cities is subject to availability. The definitive list of editable fields will be officially confirmed by IIM Indore once the correction facility is activated, so always refer to the latest official notification.

The CAT correction facility is strictly limited to selected fields to maintain the integrity of the application process. It is critical for all aspirants to understand that important personal and registration details are typically NOT available for modification. Any errors in these fields, once the correction window closes, are generally permanent and can lead to significant issues during various stages of the CAT selection process, including potential disqualification.

The fields that are typically non-editable include your candidate name, date of birth, registered email ID, registered mobile number, state, and other fundamental personal details. These pieces of information are foundational to your application and are used for all official communications and identity verification. Errors here can cause discrepancies with your other documents, such as academic certificates or identity proofs. Candidates must exercise extreme caution and double-check these details meticulously during their initial application submission.

Always refer to the official CAT instructions for the precise list of fields that can and cannot be changed during the correction window. Do not assume any field is editable unless explicitly stated in the official notification. This diligence in the initial submission phase is your best defense against irreversible errors.

Only candidates who have successfully submitted their CAT 2026 application and completed the required fee payment are expected to be eligible for the correction facility. This is a crucial precondition; if your application is incomplete or your fee transaction was unsuccessful, you will likely not gain access to the correction window. The system is designed to allow modifications only for applications that are considered complete in all basic aspects.

Conversely, candidates who do not need to change any permitted information are not required to use the correction facility. There is no compulsion to log in or make any 'dummy' changes if your submitted application is already accurate within the editable fields. However, even if you believe your application is perfect, a quick check during the window can provide peace of mind and confirm everything is in order.

To access the CAT 2026 correction facility, candidates will need their unique CAT 2026 login credentials. This includes the User ID and password that were generated and provided to you during the initial registration process. These credentials are your gateway to your application portal and are essential for making any permitted changes.

It is paramount to keep these details secure and confidential. Never share your CAT login credentials with anyone, under any circumstances, to prevent unauthorized access or tampering with your application. Always use the official CAT website, iimcat.ac.in, for the correction process to ensure you are interacting with the genuine portal and avoid phishing attempts or fraudulent websites. Regularly verifying the URL in your browser is a good practice.

Once the correction facility is activated and available, candidates should follow these precise steps to ensure their application is updated correctly:
