This guide walks you through how the correction window works, what the likely cat correction window 2026 date could be, and how to handle every step calmly and correctly.

The correction period refers to the specific timeframe during which candidates can make changes to their application.

The goal is to help you use the cat correction window 2026 smartly so that your cat application is accurate, strong and ready for mba colleges and top b schools.

What Is the CAT Correction Window and Why It Matters?

The cat exam is one of the most competitive mba entrance exams conducted by the indian institutes of management and other leading b schools. Every year, lakhs of students fill the cat application form, and many later realise that they have made errors in personal details, academic information or test city preference.

To help with this, the official cat website opens a short form correction window. During this correction period, registered candidates can log in and fix certain details in the application form after submission. The cat correction window is a one-time chance to recheck your information, re upload documents if needed, and make sure your cat application form correctly reflects your profile.

If you ignore the cat application form correction stage, you risk facing issues at later steps like document verification, interview city allocation, or even at the time of final admission process. That is why understanding the form correction process well in advance is crucial. Mockat

Trend Analysis: CAT 2023, CAT 2024 and CAT 2025 Correction Windows

Before predicting the cat correction window 2026, it is sensible to look at recent trends for cat 2024 and cat 2025, as well as cat 2023. The pattern of the correction window, last date for registration and the exam date has been fairly consistent.

How to Access the CAT Correction Window 2026

Go to the official cat website or official cat website homepage.
Click on the registered candidate login button.
Enter your user id and password as your login credentials.
Open your existing cat application form and check the editable details displayed on the screen.
Start the cat form correction process by editing the allowed sections one by one.

The form after submission is not fully editable. The cat application form correction is limited to certain details and editable details only. Therefore, you should read the instructions on the official website carefully before you edit the cat application form.

Editable Details in the CAT Application Form

The exact editable details vary slightly from year to year, but based on cat 2024 application and previous cat form correction windows, the following fields are often open for editing:

Category	Examples of editable details
Personal details	Spelling of name, date of birth, category (if allowed), some contact fields
Academic information	Year of passing, board/university name, wrong percentage corrections
Test city preference	Reordering or changing test city choices and preferred test cities
Photo/signature	Photo signature, photograph signature, photo signature and test issues, re upload of images
Other details	Interview city in some years, small corrections in work experience sections

In many years, candidates are allowed to re upload photo signature files if the earlier upload did not meet guidelines. The cat form correction window may also allow a re upload of documents related to reservation categories. In some years, candidates may also be allowed to re-upload category certificates if the earlier upload did not meet the specified guidelines.

You should note that the list of editable details is always mentioned before the correction window opens. Do not assume that every part of the cat application form is editable.

Non-Editable Fields: What You Cannot Change

While the cat application form correction is generous, some fields in the application form after submission are normally frozen. Typical non-editable sections may include:

Your name, if it conflicted with your original identity proof.
Your email id and mobile number used for user id generation.
Some personal details that are linked to your login credentials.
Some academic details once submitted, depending on the year.
Many other details such as category or PwD status, if locked after payment.

This is why you must fill the cat application form correctly during the registration process. The form after submission is not a place for major changes, only for fine-tuning certain details. Treat the correction window as a safety net, not as the main stage for completing your cat application.

Once you have submitted the corrections, you should download a copy of the updated cat application and save it for future reference in the admission process.

Common Mistakes in the CAT Application and How to Fix Them

Many issues that students fix during the cat application form correction stage are avoidable. Here are some frequent problems and how the form correction window helps:

Common mistake	What you can do in the correction window
Wrong percentage entered	Use the cat form correction to update the wrong percentage in academic details or academic information fields, if allowed.
Blurry or incorrect photo signature	Re upload clear photograph signature and photo signature files following guidelines.
Signature and test city mismatch	Correct signature and test city fields, and if needed change test city choices.
Incorrect test city preference order	Rearrange preferred test cities so that your test city aligns with travel convenience.
Missing interview city preference	If available that year, update interview city and other details.

During cat 2024 and cat 2024 exam cycle, many registered candidates needed to use the cat form correction window to re upload images or fix test city preference. The same applied for cat 2025.

It is wise to keep a checklist of certain details to verify during the cat application form correction: names, dates of birth, academic marks, category, test city, interview city (if asked), and any editable details related to work experience.

Strategy for Test City Preference and Test City Choices

One of the most important parts of the cat application form is your test city preference. This affects where you will actually sit for the cat exam, so think carefully during both the original application form and the cat application form correction stage.

Here are some tips:

Choose test city options that you can actually travel to easily.
When you first fill the cat application form, set realistic test city choices based on transport and accommodation.
During the form correction window, revisit your preferred test cities and change them if your situation has changed.
Remember that allocation is subject to availability, so you should arrange your test city preference in order of genuine priority.

Sometimes, students ignore this and later discover that their test city is far from home. The form correction process gives you a second chance to correct test city choices if the portal allows it that year. Use this intelligently rather than randomly changing your test city.

After the Form Correction Window: Admit Card, Interview City and Admission Process

Once the correction window closes, the application form after submission becomes final. After that, focus shifts to the cat admit card and the next steps in the admission process.

Usually, after the form correction window and cat form correction are over:

The admit card is released online, and you must download the admit card before the cat exam day.
The cat admit card is generated based on the final cat application form, including test city and, in some years, interview city details.
Top b schools and mba colleges use your cat 2024 exam or cat 2025 score (or later 2026 score) as part of their admission process, along with interviews and written ability tests.

Because your cat application is the base document for the entire admission process, you must ensure that all correct details were captured before the correction period ended and the correction window remained open for you to fix them.

If you face technical issues at any point, you should contact the cat help desk or cat helpdesk. They can guide you on technical errors with registered candidate login, user id, or other details related to your application form.
