AISSEE 2027 Application Form Mistakes to Avoid: Common Errors That Lead to Rejection

Most AISSEE 2027 application form rejections come from small, preventable mistakes — a name that does not match the birth certificate, a photo file that is too large, or closing the browser before downloading the Confirmation Page. NTA does not give individual warnings for these errors, and the correction window covers only a limited set of fields. Students who rush the form in the last two days of the registration period report payment failures and upload errors far more often than those who apply early. Filling the form carefully and checking every field before payment takes about 45 minutes; undoing a wrong entry that is outside the correction window is not possible.

• The Confirmation Page is proof that your application is complete. An application without a Confirmation Page is not processed — regardless of whether the fee was paid.
• One mobile number and one email address are linked to one application. A wrong digit in either field means you cannot receive your login credentials.
• Photo and signature files must be in JPG or JPEG format within specific size limits. Files outside these limits are rejected by the portal at the upload stage.
• Category misrepresentation — such as selecting Defence when there is no service connection — leads to cancellation of admission during document verification, even if the candidate qualifies the written exam.
• The application fee is non-refundable in all cases, including if the candidate does not appear for the exam or is found ineligible later.

Why AISSEE Applications Get Rejected: Quick Overview

NTA can reject an AISSEE application at three different stages: at the time of submission (portal rejects the file or the form), after submission during NTA’s internal review (photo or signature flagged as unsuitable), or at the exam centre or Sainik School during document verification (mismatch between form data and original documents). The table below lists the most common error types and at which stage each is caught.

Parents who checked their child’s Aadhaar card and birth certificate side by side before filling the AISSEE form reported fewer name and date-of-birth mismatches. The name in the form must match the birth certificate exactly — including middle names, initials, and spelling — not just the Aadhaar card, since Aadhaar details are sometimes entered with shortened names.

Personal Details Mistakes

Errors in personal details are the most common reason for rejection at Sainik School verification. Many of these errors pass through the NTA portal without any warning — the portal accepts the form because the data looks valid, but the mismatch is found when the original documents are checked at the school. Some fields can be corrected during the correction window; others cannot. Fill every personal detail field against the original documents, not from memory.

Wrong Name or Name Spelling

The candidate’s name in the form must match the name on the birth certificate exactly. This includes:

• Full name, not a shortened version. If the birth certificate says "Arjun Kumar Singh", the form must say "Arjun Kumar Singh" and not "Arjun Singh".
• Middle names must be included if they are on the birth certificate. Leaving out a middle name creates a mismatch.
• Spelling must be identical. "Vikram" and "Vikramm" are treated as different names.
• Do not enter the name in all capitals unless the form field requires it. Enter it exactly as it appears on the source document.
• Father’s name and mother’s name fields must also match the respective parent’s identity documents. Use the name on the parent’s Aadhaar card or PAN card.

Wrong Date of Birth

Date of birth must match the birth certificate. Age eligibility for AISSEE is calculated as on 31 March 2027. A wrong date of birth can make the candidate appear overage or underage, which leads to cancellation during verification even if the candidate qualifies the written exam.

• Check the date of birth on the birth certificate before entering it. Do not use the date on the school ID card or the transfer certificate, as these sometimes have transcription errors.
• Enter the date in the format the portal requires (usually DD/MM/YYYY). Entering the month and day in the wrong order (for example, 08/11/2014 when the correct date is 11/08/2014) changes the date of birth entirely.
• This field can be corrected during the correction window, but you must carry the original birth certificate at the exam centre to show the corrected entry is legitimate.

Wrong Mobile Number or Email Address

These two fields are filled at the registration step, before the form proper. NTA sends the Application Number and login password to the mobile number and email you enter here. An error at this step means you cannot log in to complete the form.

• Enter the mobile number digit by digit. A single wrong digit means the SMS with your credentials goes to a stranger.
• Type the email address carefully. Email addresses with common typos like "gmial.com" instead of "gmail.com" are accepted by the portal but receive nothing.
• Use a mobile number and email you will keep active until May 2027. NTA sends the admit card, result, and school communication to these contacts. Do not use a number that will change or a temporary email address.
• If you entered a wrong mobile number and did not receive your credentials, contact the NTA helpdesk immediately with the correct number and the email you entered. This is the only way to recover — the portal does not let you re-register with the same details.

Wrong Category Selection

The category field (General, SC, ST, OBC-NCL, EWS, Defence) affects the fee you pay and the seats you are eligible for. Selecting a wrong category is a serious error.

• Select OBC-NCL only if the candidate has a valid OBC Non-Creamy Layer certificate issued by the District Magistrate or Tehsildar. An OBC certificate without the Non-Creamy Layer status qualifies as General for AISSEE.
• Select SC or ST only if the community certificate is in the candidate’s name. A parent’s SC or ST certificate is not sufficient.
• Select EWS only if the candidate has a valid EWS income and asset certificate for the current financial year issued by the competent authority.
• Select Defence only if the candidate is a ward of a serving, retired, or deceased personnel of the Indian Army, Navy, or Air Force. Children of CAPF personnel (CRPF, BSF, CISF, ITBP, SSB), state police, and paramilitary forces do not qualify as Defence category for AISSEE.
• Misrepresenting category does not just affect the fee. It leads to cancellation of the seat at Sainik School after verification, even after the candidate has joined the school.

Using the Candidate’s Own Mobile and Email

The mobile number and email entered at registration must belong to the candidate (or be permanently accessible to the candidate’s family). Some parents use a teacher’s or relative’s number for convenience, then cannot access it later when the admit card or result is sent. Use a number and email that the family controls directly throughout the entire process.

Photo and Signature Errors

Photo and signature errors are the second most common cause of form rejection. The portal rejects files outside the size or format limits at the upload stage. Even if the portal accepts the file, NTA can flag it as unsuitable during its internal review after registration closes. In that case, NTA opens a correction window for re-upload. But if you miss that window, the application may not get an admit card.

Allowed File Specifications (Based on AISSEE 2026)

Verify exact limits in the official AISSEE 2027 information bulletin once NTA releases it. These figures are from AISSEE 2026.

Common Photo Mistakes

• File too large: Smartphone cameras produce 2 MB to 5 MB photos. These are far above the 200 KB limit and will be rejected. Compress the image to under 200 KB using a free image tool. Make sure the face stays sharp and recognisable after compression — a blurry face is flagged during NTA review.
• Wrong format: PNG, HEIC, and WebP files are not accepted. If your photo was saved in one of these formats, open it in any image tool and export it as a JPEG file with the .jpg or .jpeg extension.
• Coloured or patterned background: The photo must have a plain white or very light background. A coloured wall, curtain, or outdoor background is rejected at the exam centre during verification, even if the portal accepted the file at upload.
• Old photo: The photo must have been taken in the last three months. A passport photo from last year or a photo cropped from a group picture is not acceptable. The candidate must look the same in the photo as on exam day.
• Name and date not printed: The candidate’s name and the date the photo was taken must be printed below the image before scanning. This is checked at the exam centre.
• Sunglasses or cap: Both are not allowed unless the cap is religious headgear. Both ears must be visible.

Common Signature Mistakes

• Parent signing instead of candidate: The signature must be the candidate’s own. For Class 6 students who are young and may not have a consistent signature, a clearly written name in cursive or block letters is generally accepted. Check the official instruction booklet on exams.nta.nic.in for the exact rule for young candidates.
• Digital or printed signature: A typed and printed name or a digitally drawn signature is not accepted. The candidate must physically sign on white paper in black or blue ink.
• Signing on ruled paper: The lines on ruled or graph paper show on the scanned image. Sign on a plain white sheet of paper only.
• File too large or too small: The signature file must be between 4 KB and 30 KB. A full-page scan of the signature sheet will usually be far over 30 KB. Crop the image to show only the signature on a white background, then compress if needed.
• Non-JPEG format: Same rule as the photo — the file must be in JPG or JPEG format. Convert if needed before uploading.

What to Do If the Upload Is Rejected

If the portal shows an error at the upload stage, fix the file and retry before proceeding to the payment step. You cannot pay until both the photo and signature are successfully uploaded. If NTA flags the file during its internal review after registration closes, watch for the correction window announcement on exams.nta.nic.in. During this window, log in and replace the flagged file with a correct one. Do not wait for the last day of the correction window — replace it as soon as you see the notification.

Class, Age, and School Preference Errors

Errors in the class applied for, the candidate’s age, and school preferences are often overlooked because they seem straightforward. These mistakes are harder to fix than personal details errors — class selection cannot be changed at all after submission, and school preferences can only be changed during the correction window.

Applying for the Wrong Class

AISSEE 2027 is open for Class 6 and Class 9 admissions. These are two separate applications. The most common mistake here is applying for Class 9 when the candidate is currently in Class 7 and wants to join Class 8 at a Sainik School. AISSEE Class 9 is for admission to Class 9 at Sainik Schools — the candidate must meet the age and qualification criteria for Class 9 admission, not Class 8.

• For Class 6 admission: The candidate must be studying in Class 5 at the time of application and must be between 10 and 12 years old on 31 March 2027.
• For Class 9 admission: The candidate must have passed Class 8 and must be between 13 and 15 years old on 31 March 2027.
• The class applied for cannot be changed after submission. If you select Class 9 when you mean Class 6, you cannot switch later. You would need to apply again with a new registration, which requires a new fee payment and is only possible before the registration deadline.

Age Eligibility Errors

Age is calculated as on 31 March 2027. Check the candidate’s date of birth against the eligibility range before filling the form. Applying when overage or underage leads to cancellation during Sainik School verification.

A candidate born on 1 April 2014 is 12 years and 11 months on 31 March 2027 and qualifies for Class 6 (within the 10 to 12 range). A candidate born on 31 March 2012 is exactly 15 years on 31 March 2027 and qualifies for Class 9. Candidates born before 1 April 2012 are overage for both classes. These boundaries are strict — there is no grace period.

School Preference Mistakes

The AISSEE form lets you list multiple Sainik Schools in order of preference. A common mistake is listing only one or two schools and leaving the rest blank. This reduces your chances significantly.

• Fill every available preference slot. Schools in your home state are allocated under the state quota, which covers 67% of seats. List your home-state schools first.
• Schools under the All-India quota take the remaining 33% of seats. If you do not list enough schools, you may miss a seat even if your rank qualifies for a school you did not list.
• Defence category students have a separate quota. If you are in the Defence category, also fill preferences for schools in states where the parent is posted, as applications are processed based on the parent’s posting state for the Defence quota.
• School preferences can be changed during the correction window after registration closes. Use that opportunity to review and update your list if needed.

Exam City Preference Mistakes

AISSEE candidates choose up to four exam city preferences on the form. NTA allocates the exam centre from these choices. Mistakes here are less severe than class or age errors, but they can affect convenience on exam day.

• List four different cities instead of repeating the same city multiple times. If your first choice is unavailable, NTA assigns from your remaining preferences.
• Choose cities with good rail or road connectivity. Exam centres in your city or a nearby city are easiest to reach.
• Exam city preferences can be changed during the correction window.

Fee Payment and Submission Mistakes

Payment is the last step before the application is complete. Many families who fill the form correctly lose it at this stage by closing the browser too early, using an unreliable payment method, or not downloading the Confirmation Page. An application where the fee was paid but the Confirmation Page was not generated is treated as incomplete by NTA.

Closing the Browser Mid-Payment

This is the single most common submission error. After clicking Pay, the portal redirects to the bank or UPI gateway. Closing the browser tab, pressing the back button, or letting the session time out at this point leaves the application in a pending state. The fee may be deducted from the bank account, but the Confirmation Page is not generated.

• Do not close the browser until the Confirmation Page appears on the screen after payment.
• Do not press the back button after clicking Pay.
• Use a stable internet connection for the payment step. A dropped connection mid-payment causes the same problem.
• If the fee is deducted but the Confirmation Page does not appear, log in again after 24 to 48 hours and check the application status. If it still shows incomplete, contact the NTA helpdesk with your bank transaction ID and application number.

Not Downloading the Confirmation Page

After a successful payment, the portal generates the Confirmation Page. Many candidates close the browser immediately after seeing a success message without downloading this page. NTA does not automatically email or post the Confirmation Page.

• Download the Confirmation Page immediately after it appears. Save a digital copy and take a printout.
• The Confirmation Page is required at the exam centre when collecting the admit card and at Sainik School at the time of admission. Keep it safe from now until admission is complete.
• Your application is considered complete only when the Confirmation Page is generated. A status of "partially filled" or "fee pending" means the application is not complete.

Paying Through Unofficial Channels

The application fee must be paid through the official NTA payment gateway on exams.nta.nic.in. No other payment method is valid.

• Do not pay through any agent, coaching centre, cybercafe operator, or third-party website, even if they claim to be authorised.
• Do not pay based on a link received by SMS or WhatsApp from an unknown number. NTA does not send payment links by SMS.
• Payments made outside the official gateway are not credited to your application. You would need to pay again through the official portal, and the unofficial payment is unlikely to be refunded.

Duplicate Applications

Submitting more than one application for the same class is a common error when a family is unsure whether the first application went through. Duplicate applications are flagged during NTA’s processing and can result in both applications being cancelled.

• Before starting a new registration, log in to your existing account and check the application status. A status of "submitted" or "complete" with a downloadable Confirmation Page means the application is already done.
• If you are unsure, contact the NTA helpdesk with your Application Number to confirm the status before starting a second registration.
• Separate applications for Class 6 and Class 9 are not duplicates — these are permitted and expected, each with its own registration and fee.

Last-Day Submission Risks

The NTA portal for AISSEE experiences significantly higher traffic on the final day of registration. Server slowdowns, payment gateway timeouts, and upload failures are much more common on the last day than at any other time in the window.

• Apply at least a week before the expected deadline. If a photo file is rejected or a payment fails, you have time to fix it and resubmit.
• If you must apply on the last day, start early in the morning rather than in the evening, when traffic is highest.
• Keep the official NTA helpdesk number saved so you can call immediately if you face a technical issue on the last day.

Using the Correction Window Correctly

NTA opens a correction window for a few days after the registration period closes. This is the only opportunity to fix errors in a submitted application. The window covers specific fields only. Errors outside these fields cannot be corrected under any circumstances after the window closes.

What Can Be Changed in the Correction Window

• Candidate’s name, date of birth, and gender (with supporting documents at the exam centre)
• Category selection (with the correct certificate ready for the exam centre)
• Exam city preferences
• Sainik School preferences
• Photo or signature, if NTA has flagged either file as unsuitable
• Parent details and address

What Cannot Be Changed After Submission

• The class applied for (Class 6 or Class 9)
• The application number
• The mobile number and email used at registration
• The fee paid (no transfer to a different application, no refund)

How to Use the Correction Window

Log in to exams.nta.nic.in with your Application Number and password during the correction window dates. Navigate to the application form and make the changes needed. Save each change before moving to the next field. Download a fresh copy of the Confirmation Page or application printout after making corrections, as it will reflect the updated details.

Parents who discovered a name mismatch or date-of-birth error after submitting the AISSEE form have been able to correct it during the correction window provided they acted promptly. The window typically stays open for 5 to 7 days. Missing this window means the error stays on the application permanently, and the only remedy at that point is to carry the original birth certificate at every stage and hope the school accepts the explanation.

Keep the Correction Window Dates Noted

NTA announces the correction window dates on exams.nta.nic.in after the registration closes. There is no fixed schedule published in advance. Check the official portal daily in the week after registration closes and act immediately when the window opens. Do not wait for the last day of the correction window.
