CBSE Board Exam 2027 LOC Data Correction Window Opens for Classes 10 and 12
The Central Board of Secondary Education (CBSE) has opened a correction window for List of Candidates (LOC) data submitted for Class 10 and Class 12 Board Examinations 2027. The correction notice is dated November 2, 2026. It gives schools another opportunity to check students’ examination details and correct permitted errors.
The LOC is the list of candidates submitted by an affiliated school to CBSE for the board examinations. Students and parents should contact their school if they find an error; corrections are handled through the school’s authorised access to the CBSE process.
Important dates and details

|---|---|
| CBSE correction circular issued | November 2, 2026 |
| Correction window opens | November 2, 2026 |

Deadline note: CBSE’s official circular page lists the new correction circular dated November 2. The earlier official LOC notice and later correction schedule should be checked together because the dates reported for the closing day do not appear consistent across available schedule information. Students should ask their school to verify the closing date shown in the school’s CBSE portal and submit any correction request as early as possible.
What details should students check?
CBSE’s correction notice refers to checking candidate particulars, including the student’s name, father’s, mother’s or guardian’s name, date of birth, and subject offered. Compare the LOC details with the student’s school records and supporting documents. Subject information deserves particular attention because it determines the examination papers for which the student is registered.
Do not assume that every field can be changed. The school should confirm whether the requested correction is permitted and what supporting documents are required. CBSE has stated that another opportunity for corrections will not be provided after the applicable window closes.
What students and parents should do
- Ask the school to show or confirm the student’s LOC details.
- Check the spelling of the student’s name and parents’ or guardian’s names, date of birth, and subjects.
- Report any error to the school in writing and provide the documents it requests.
- Ask the school to confirm that the correction was submitted successfully before the deadline.
- Keep a copy of the school’s confirmation for reference.
Students should not wait until the final day to report a mistake. Since the correction facility is administered through schools, the school’s examination office is the first point of contact for checking the correction schedule and the status of a submitted request.
