What Is the CAT 2026 Form Correction Window?<\/h2>\n\n\n\n

The CAT form correction window is a short, one-time facility that opens after<\/strong> the registration deadline closes. It exists because, out of the lakhs of candidates who apply, a fair number end up with a photo that doesn’t meet the size specification, a signature that’s too dark or too light, or a test city they want to reconsider. Instead of making candidates start over, IIM Indore reopens the login portal for a few days, allowing them to correct these specific details before generating the admit card.<\/p>\n\n\n\n

It’s worth being clear about what this window is not<\/em>: it isn’t a second chance to re-fill your entire form. The form locks your name, date of birth, category, email address, and mobile number as soon as you submit it, and you cannot change these details during the correction window. Think of it as a narrow repair window for a handful of fields \u2014 not a form reset.<\/p>\n\n\n\n

Since CAT 2026 registration was extended by a week (from September 15 to September 22, 2026<\/mark><\/a>), the correction window is also expected to shift slightly later than in a typical year. IIM Indore hasn’t confirmed exact dates yet, but based on how the last few cycles played out, here’s what the pattern tells us.<\/p>\n\n\n\n

CAT 2026 Correction Window: Expected Dates<\/h2>\n\n\n\n

Important:<\/strong> IIM Indore has not officially announced the CAT 2026 correction window dates as of this update. What follows is a data-backed estimate based on the last five CAT cycles \u2014 always cross-check the live schedule on iimcat.ac.in<\/mark><\/a> before you make plans.<\/p>\n\n\n\n

CAT Year<\/th>Registration Closed<\/th>Correction Window<\/th>Gap After Registration<\/th><\/tr><\/thead>
CAT 2022<\/td>Mid-September 2022<\/td>September 23\u201326, 2022<\/td>~9 days<\/td><\/tr>
CAT 2024<\/td>September 13, 2024<\/td>September 27\u201330, 2024<\/td>~14 days<\/td><\/tr>
CAT 2025<\/td>September 20, 2025 (extended)<\/td>Opened October 4, 2025<\/td>~14 days<\/td><\/tr>
CAT 2026<\/td>September 22, 2026 (extended)<\/td>Expected early\u2013mid October 2026<\/td>~10\u201314 days (projected)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The pattern is fairly consistent: IIM Indore typically activates the correction facility 10 to 14 days<\/strong> after registration closes, and keeps it open for 3 to 4 days<\/strong>. Applying that same gap to this year’s extended deadline of September 22 puts the most likely window somewhere in the first two weeks of October 2026<\/strong> \u2014 but treat this strictly as an estimate until the official notice drops.<\/p>\n\n\n\n

What Details Can Be Edited in the CAT 2026 Application Form?<\/h2>\n\n\n\n

This is the part candidates get wrong most often \u2014 the correction window is a narrow, specific fix, not a full re-edit. Here’s the breakdown based on how the facility has worked in every recent CAT cycle. <\/p>\n\n\n\n

Category<\/th>Fields<\/th><\/tr><\/thead>
Editable during correction window<\/strong><\/td>Photograph, signature, test city preference (order\/choice)<\/td><\/tr>
Locked \u2014 cannot be edited<\/strong><\/td>Name, date of birth, category (General\/OBC-NC\/EWS\/SC\/ST\/PwD), email ID, mobile number, academic qualification details<\/td><\/tr>
Requires helpdesk\/query route (not the correction portal)<\/strong><\/td>Genuine, provable errors in name or date of birth<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

If your photograph doesn’t meet the required pixel size or your signature scan looks smudged, use the correction window to re-upload the correct files and fix them. Same goes for test city: if you want to reorder your preferences or swap one city for another (subject to seat availability), you can do that here too.<\/p>\n\n\n\n

Step-by-Step Process: How to Correct Your CAT 2026 Application Form<\/h2>\n\n\n\n

Once the correction link goes live, here’s the process you’ll follow. It takes most candidates under 10 minutes if their new photo\/signature files are ready in advance.<\/p>\n\n\n\n

    \n
  1. Visit the official CAT 2026 website<\/strong> at iimcat.ac.in<\/mark><\/a> \u2014 this is the only legitimate portal; don’t trust third-party “correction” links shared on social media.<\/li>\n\n\n\n
  2. Click on “Registered Candidate Login”<\/strong> and sign in using the User ID and password you created during registration.<\/li>\n\n\n\n
  3. Locate the “Application Form Correction” link<\/strong>, which will only be visible once the window is officially active.<\/li>\n\n\n\n
  4. Edit the permitted fields<\/strong> \u2014 upload a new photograph or signature if needed, or update your test city order.<\/li>\n\n\n\n
  5. Double-check every change<\/strong> before saving. There’s no confirmation SMS reminding you to review, so this step matters.<\/li>\n\n\n\n
  6. Click Save, then Submit<\/strong> the corrected form.<\/li>\n\n\n\n
  7. Download and print the updated confirmation page<\/strong> for your records \u2014 you may need it at your exam center or for future reference.<\/li>\n<\/ol>\n\n\n\n

    A tip that saves a lot of last-minute stress: get your new photograph and signature scans ready before<\/strong> the window opens, in the exact specifications mentioned in the CAT 2026 information bulletin (usually JPEG format, specific pixel dimensions and file size limits). That way, you’re not scrambling to scan documents in the final hours of a 3\u20134 day window.<\/p>\n\n\n\n

    Is There a Fee for CAT 2026 Form Correction?<\/h2>\n\n\n\n

    No. IIM Indore does not charge any additional fee for the form correction facility, and this applies uniformly across all categories \u2014 General, EWS, NC-OBC, SC, ST, and PwD. You’ve already paid your registration fee (\u20b92,700 for General\/EWS\/NC-OBC, \u20b91,350 for SC\/ST\/PwD); the correction window doesn’t add to that.<\/p>\n\n\n\n

    What If You Have an Error in a Locked Field?<\/h2>\n\n\n\n

    If you spot a genuine mistake in a field the correction portal doesn’t let you touch \u2014 say, a typo in your date of birth that doesn’t match your official documents \u2014 the correction window itself won’t help. In such cases, IIM Indore generally expects you to raise a query through the official candidate grievance\/query facility on the portal, along with supporting documents. There’s no guarantee of resolution, so the real fix is prevention: cross-verify every entry against your original certificates before<\/em> you submit the primary form, not after.<\/p>\n\n\n\n

    CAT 2026 Correction Window vs Registration Window<\/h2>\n\n\n\n

    Candidates often mix up these two stages, so here’s a direct comparison.<\/p>\n\n\n\n
