The exact last date for verification or submission of documents for promotion from Class 9 to Class 10 in 2025 varies depending on the education board and the specific school you are enrolled in. Each state board or central board like CBSE sets its schedule, and schools often have internal deadlines for submitting necessary documents for verification.

Typically, verification and document submission for Class 9 to 10 promotion happen during the academic session—often between February and April—before the final examinations or at the commencement of the new academic year. However, the precise dates are announced by the respective education boards or schools.

It is best to check with your school authorities or the education board’s official website for the exact deadline applicable to your region and school in 2025. Schools usually inform students and parents ahead of time about such verification deadlines to ensure timely compliance.

In summary, the last date for Class 9 to Class 10 verification is decided by your school and education board, and usually falls 1–2 months before the academic session or board exams begin. Confirm directly with your school or board to avoid missing the deadline.
