What is CAT Correction Window 2026?

The CAT correction window is a limited, one-time facility provided by IIM Indore — the conducting body for CAT 2026 — that lets registered students fix specific errors in their submitted application forms. It opens after the registration period closes and stays active for a short period, typically one to two days.

For CAT 2026, the correction window was active from October 5, 2026 (10:00 AM) to October 6, 2026 (5:00 PM). Within this 31-hour window, students could update three fields: their uploaded photograph, their signature image, and their test city preferences. Every other field — including name, date of birth, category, gender, educational qualifications, and work experience — was locked and could not be modified.

The correction window is governed by the official CAT 2026 brochure issued by IIM Indore. The brochure makes clear that this is the sole opportunity to correct application errors; once the window closes, no further modifications or appeals for data changes are entertained. Students who missed the window must contact the helpdesk for case-by-case review.

Pay the correction fee within the window — unpaid corrections will not be saved. Since CAT 2026 carried no fee, all changes submitted and confirmed before the window closed on October 6, 2026 were saved automatically upon confirmation.

CAT Correction Window 2026: Errors & Problems

Several common technical and procedural issues arise during the correction window. The table below lists these problems, their likely causes, and the recommended steps to resolve them — useful for troubleshooting or for reference in the next cycle.

CAT Helpdesk

For unresolved issues related to the CAT 2026 application, correction window, or upcoming admit card, students can contact the official CAT 2026 helpdesk managed by IIM Indore.

When contacting the helpdesk, always include your CAT 2026 Application Number (CAT ID), registered email address, and a brief but precise description of the issue. Response times may be longer in the days immediately following the close of the correction window due to high query volume.

CAT Form Correction 2026: Important Tips

These tips apply to managing your CAT 2026 application through the remaining stages of the exam cycle.

1. Download your updated application form immediately — this PDF is your official record of any corrections made and may be needed at the interview stage if a discrepancy is raised.
2. Before uploading photos or signatures during any future cycle, verify file format and size against the brochure specs first — wrong format is the most common reason for upload failure.
3. Check your registered email inbox regularly from now until results are declared; IIM Indore sends all official communications — admit card links, result notifications, and PI/WAT interview calls — there.
4. When selecting test city preferences, always choose three geographically distinct cities. Listing the same city three times does not improve your chances of being allotted that city; IIM Indore allots based on seat availability.
5. Never share your iimcat.ac.in login credentials with coaching centres, consultants, or anyone else — all actions performed under your account are your responsibility.
6. Bookmark iimcat.ac.in and check it every few days for admit card release dates, exam-day guidelines, and result announcements.
7. If you missed the correction window and there is an error in your form, document the discrepancy with screenshots and contact helpdesk@iimcat.ac.in promptly — earlier contact gives a better chance of resolution before the admit card is issued.
8. Do not rely on third-party websites for correction window dates, direct login links, or portal updates; only iimcat.ac.in carries authoritative information.
