IIM CAT 2026 & XLRI XAT 2027 Correction Windows – Dates, Editable Fields and What It Means

By the Shiksha Nerd Counselling Team · 1 October 2026 · ~4 min read

The IIMs have released the CAT 2026 correction window and XLRI has done the same for XAT 2027. Here’s a concise guide on dates, what you can edit, and the practical steps you must take right now.

The Indian Institutes of Management (IIMs) have finally published the correction window for CAT 2026, and XLRI Jamshedpur has done likewise for XAT 2027. Both notifications appear in the latest bulletins and lay out a short, fixed period during which applicants can log in and amend specific parts of their online forms.

This matters to anyone who sat for the CAT in November 2026 or the XAT in December 2026 and has already submitted an application. A single typo in a birth‑date or a missing digit in a roll number can derail a candidate’s eligibility, and the correction window is the only official chance to fix it before the selection committees freeze the data.

CAT 2026 correction window – schedule and editable fields

According to the News18 report, the IIM‑led CAT authority has announced a correction period that will open on a date mentioned in the official notification and close after a few days. The exact start and end dates are not reproduced here, but candidates should mark them as soon as they appear on the CAT portal.

The notice also splits the application fields into two buckets. Editable items include personal details (full name, date of birth, gender), contact information (mobile number, email) and academic entries (board, year of passing, marks obtained). Locked items – such as the preferred test centre and the list of MBA programmes you selected – cannot be altered once the form is submitted.

XAT 2027 correction window – schedule and editable fields

Shiksha.com’s coverage of the XAT 2027 correction window mirrors the CAT announcement. XLRI has set a window – again, dates are on the official notification – that opens a few weeks after the XAT exam and remains active for a limited number of days.

Editable fields for XAT are essentially the same: personal, contact and academic details can be changed. The only notable addition is that any amendment to the “work‑experience” section now requires you to upload a supporting document (such as an appointment letter) during the correction phase. As with CAT, the test‑centre choice and programme preferences stay locked.

Key differences and practical implications

While both exams give you a narrow window to correct mistakes, the XAT notice explicitly calls out the need for document upload when you tweak work‑experience data. CAT does not mention a new upload requirement, meaning the original documents you submitted earlier remain valid.

Another subtle difference is the timing of the windows. The CAT correction period is announced by the IIMs and traditionally starts a week after the exam, whereas the XAT window, as per XLRI, may begin slightly later. For a candidate juggling multiple applications, the staggered dates can be a blessing – you can focus on one correction at a time – or a source of stress if the windows overlap.

Counsellor’s take: when to rely on the window

From a counsellor’s perspective, the correction window is a safety net, not a planning tool. It’s perfect for fixing genuine clerical errors – a swapped digit in a roll number or a missing digit in a phone number. However, it should never be used to make strategic changes like swapping your preferred MBA college; those choices are locked and will affect your chances in the next cycle.

Students who are unsure about their work‑experience description should treat the XAT window as an opportunity to attach a clean, verified letter, but they must also be ready with the document beforehand. If you are comfortable with the data you entered, you might even skip the window to avoid any accidental overwrite.

What should you do now?

1. Mark the start and end dates on the official notification as soon as they are published.
2. Log in to the CAT or XAT portal a day before the window opens and verify which fields are flagged as editable.
3. Gather any required supporting documents – mark sheets for academic edits, appointment letters for work‑experience changes – so you can upload them instantly.
4. Cross‑check every editable entry against your original certificates; correct one, save, then move to the next.
5. Submit the corrected form well before the deadline; a few hours buffer protects you from server overload.
6. Take a screenshot of the final confirmation page and store it in a safe folder for future reference.

Frequently asked questions

Can I change my preferred MBA programme during the correction window?

No. Both CAT and XAT lock the programme preferences once the initial application is submitted. Changing them would require a fresh application in the next admission cycle.

Is there any extra fee for making corrections?

The announcements do not mention any additional charge. The fee you paid at the time of application covers the correction process.

What if I miss the correction deadline?

Your application will be processed with the data you originally submitted. Any uncorrected error could lead to disqualification or a lower chance of selection.
