CBSE Board Exam 2027 LOC Correction Window from November 2; Check Class 10, 12 Details

The Central Board of Secondary Education (CBSE) is scheduled to open the List of Candidates (LOC) correction window for the 2027 Class 10 and Class 12 board examinations from November 2 to November 4, 2026. The verification period will give schools and candidates an opportunity to identify errors in the submitted examination data and follow the board's prescribed correction procedure.

The CBSE LOC process is important because the information submitted by affiliated schools is used to register eligible students for the board examinations. Candidates should check their personal details carefully and immediately inform their school authorities if they find any discrepancies. Schools are responsible for handling the LOC submission and correction process in accordance with the board's instructions.

CBSE LOC Correction Window 2027: Important Dates

The CBSE Board Exam 2027 LOC schedule includes the initial registration period, the late-fee submission period and the subsequent data verification window. Students and schools should keep the following dates in mind.

The regular LOC submission deadline has passed. Schools that still need to complete the prescribed late-fee submission process should follow the applicable CBSE instructions. The correction window is a separate stage intended for checking submitted data and should not be confused with the initial registration deadline.

CBSE Board Exam 2027: Which Details Should Students Check?

Students appearing for the CBSE Class 10 and Class 12 board examinations in 2027 should carefully review their details during the prescribed verification process. Any discrepancy should be reported to the school without delay.

The important details to verify include the following:

• Student's full name and spelling

• Date of birth

• Father's name and mother's name, wherever applicable

• Parent or guardian details

• Subjects selected for the board examination

• Other personal and examination-related information recorded in the submitted LOC

Students should pay particular attention to the spelling of their names and their date of birth. They should also ensure that the subjects recorded against their names match their approved subject choices.

The correction of subject details may be governed by separate restrictions under CBSE rules. Therefore, students should not assume that every field can be changed during the verification window. The school must follow the applicable circular and correction instructions issued by the board.

How to Check and Correct CBSE LOC Details for 2027 Board Exams

Students should contact their respective schools to verify the information submitted through the List of Candidates process. The LOC is handled by affiliated schools, so students should not assume that they can independently edit their examination registration details through a public login.

The general procedure is as follows:

Step 1: Contact the school administration or the teacher responsible for board examination registration.

Step 2: Ask the school to check the candidate details submitted in the CBSE LOC for the 2027 board examinations.

Step 3: Compare the recorded information with the student's available school records and supporting documents.

Step 4: Report any spelling errors, incorrect dates of birth or discrepancies in parent or guardian details to the school authorities.

Step 5: Ask the school to follow the applicable CBSE instructions for making permitted corrections during the prescribed window.

Step 6: Confirm with the school that the correction request has been processed and the relevant information has been verified.

Students should complete these checks within the stipulated period. They should also retain any acknowledgement or confirmation provided by the school regarding their correction request.

CBSE Class 10, 12 Board Exams 2027: Why Is LOC Verification Important?

The List of Candidates is a key part of the CBSE board examination registration process. It records the details of students being sponsored by affiliated schools for the examinations.

Errors in candidate information can create administrative difficulties during subsequent examination-related processes. Incorrect personal details may also lead to inconsistencies in school and examination records. This is why CBSE has repeatedly emphasised the importance of accurate LOC submission.

Students should also verify their subject combinations carefully. A discrepancy in the selected subjects should be reported immediately because changes to subjects and other registration details may be restricted under the board's applicable rules.

For Class 10 students, the 2027 examination cycle also involves the board's two-examination system. Students and schools should therefore follow the specific instructions applicable to the relevant examination session rather than assuming that every registration or correction facility follows the same procedure.

What Happens After the CBSE LOC Correction Window Closes?

The scheduled correction window is from November 2 to November 4, 2026. Students should not wait until the final day to report errors in their registration information.

After the prescribed window closes, further corrections may be restricted or unavailable under the applicable CBSE rules. Any subsequent request will depend on the board's instructions and the nature of the correction sought. Students should not assume that an additional opportunity will automatically be provided.

Schools should also ensure that corrections are completed through the authorised process and that the final information is accurate. Candidates who identify an error after the deadline should immediately contact their school to determine whether any permitted procedure remains available.

CBSE Board Exam 2027: What Should Students Do Now?

Students appearing for the CBSE Class 10 and Class 12 board examinations in 2027 should contact their schools and confirm the status of their LOC data. They should verify their personal information, parent or guardian details and subject choices before the scheduled correction window.

The most important step is to report discrepancies promptly and follow the school administration's instructions. Students should rely on official CBSE notices for any changes to the correction schedule or rules.
