AISSEE Correction Window: Full Guide

Last verified: 2 October 2026. The dates marked CONFIRMED are from the AISSEE 2026 information bulletin as reported by two independent education portals. Everything about the 2027 cycle — including which fields are editable — is marked EXPECTED until the bulletin releases.

Every year the same story repeats. A parent fills the AISSEE form in a hurry, uploads the photo, pays the fee, hits submit — and only then notices the child’s name doesn’t match the birth certificate, or the category is wrong. Then comes the panicked question: can I fix this?

Yes — once. NTA opens a short correction window after the application deadline. Last year it lasted exactly three days (CONFIRMED: 2–4 November 2025, reported by the Times of India citing the NTA bulletin and by Careers360). Three days is not a safety net; it is a lifeline. The parents who need it least are the ones who never use it. This guide explains what the window is, when to expect it for AISSEE 2027, and — most importantly — how to submit a form so clean you never open the correction portal at all.

What the correction window actually is

After the application window closes, NTA opens the correction portal for a few days so candidates can fix mistakes in their submitted forms. It is announced in the information bulletin with the application schedule — for AISSEE 2026 the bulletin gave the correction dates upfront (CONFIRMED, via TOI).

Two things every parent should internalise:

1. It is short. Three days last year. NTA has never extended an AISSEE correction window on record that we can verify — do not plan around a second chance.
2. It is not a second application. You can correct what you submitted, but you cannot submit a fresh form, change your identity, or fix an unpaid fee after the deadline.

When to expect the AISSEE 2027 correction window (EXPECTED)

The window always lands right after the application deadline closes, before the admit cards. Here is the pattern from the last cycle:

The notification is still not out, so no 2027 dates exist yet. When the bulletin drops, note the correction dates immediately and set two reminders — one on the first day of the window, one on the last morning.

What you could likely edit — and what stays locked (EXPECTED)

Everything in this section is EXPECTED, based on how NTA has run correction windows in past AISSEE cycles — not a confirmed 2027 list. The final list comes only in the 2027 information bulletin.

Typically editable:

• Name spelling (must match the birth certificate)
• Date of birth
• Gender
• Category (General / OBC-NCL / SC / ST) — a category change can trigger a fee adjustment
• Exam-city preferences (see our exam-city choices guide before you finalise)
• Uploaded photograph and signature (wrong background or blurry scan is the single most common correction)
• Parent/guardian details and address

Typically NOT editable:

• Registered email ID and mobile number — these are your login identity
• Application number
• Anything after the window closes

A word on category changes: if you filled General and are actually eligible for SC/ST (or the reverse), fix it in the window. A category mismatch between your form and your certificate can sink your admission at document verification — see our caste certificate format guide for what the bulletin expects.

The five mistakes that actually send parents to the correction window

From the patterns in parent groups and helpdesk queries each year, the repeat offenders are:

1. Name mismatch with the birth certificate. Middle names dropped, initials expanded differently — the form must match the certificate exactly.
2. A category claim with no certificate. Claiming OBC-NCL or SC/ST without a valid certificate is worse than useless; it risks rejection. If your certificate is still in process, our domicile certificate guide shows how slow paperwork can be — start now.
3. Unreadable uploads. A photo taken against a patterned wall, a signature cropped by the scanner, a thumb impression that is just a smudge.
4. Wrong exam-city order. Cities are allotted on preference — a careless order can hand your child a centre 300 km away.
5. The father’s-name/mother’s-name swap or spelling error. Small field, big downstream pain in counselling documents.

The pre-submit verification checklist

Run this table before you pay and submit. Print it if you can.

After submitting, download and save the confirmation page and the application number the same day. If you do use the correction window, re-download the confirmation page after every edit and keep both versions.

How to use the window if you need it

1. Log in to the correction portal on day one, not day three — servers slow down at the end.
2. Edit only what is wrong. Every field you touch is a field you could newly break.
3. If a category change alters your fee, pay the difference immediately and save the receipt.
4. Submit, then re-verify: view the full form again before logging out.

And remember: the window corrects the form, not eligibility. An ineligible candidate with a perfectly corrected form is still ineligible — check the age limits and qualification rules in the bulletin first.

When is the AISSEE 2027 correction window?

Not announced yet. Last year it ran 2–4 November 2025, right after the application deadline — expect a similar short window once the 2027 bulletin releases its dates.

What can I edit in the AISSEE form correction window?

Based on past NTA practice: name spelling, date of birth, category, photo and signature uploads, and exam-city preferences. The 2027 bulletin carries the final list.

What cannot be edited?

Typically your registered email ID, mobile number, and application number — these identify your application, so verify them before first submission.

What happens if I miss the correction window?

NTA does not reopen it. Errors like category mismatches or unreadable photos can lead to rejection at scrutiny or document verification.

Is there a fee for corrections?

No separate correction fee in recent cycles, but a category change that alters your fee slab means paying the difference. Confirm in the 2027 bulletin.
