Subject: Application for Leave

Dear Principal,
I am writing this letter to formally request a leave of absence from school for [number of days] starting from [date]. I have a valid reason for this leave and I hope for your understanding and approval.

Reason for Leave:
- Specify the reason for your leave in detail. Whether it is due to illness, a family emergency, or any other valid reason, make sure to explain it clearly.

Duration of Leave:
- Mention the exact dates you will be absent from school and when you expect to return. This will help the school administration make necessary arrangements during your absence.

Academic Plan:
- Assure the principal that you will make up for any missed assignments, tests, or projects during your absence. Offer to meet with teachers to discuss a plan for catching up on missed work.

Parent/Guardian Contact Information:
- Provide contact details for a parent or guardian who can be reached in case of any emergency during your absence. This will ensure that the school can easily get in touch with someone responsible for you.

Request for Approval:
- Politely request the principal to approve your leave and assure them that you will return to school promptly after the specified duration.

Thank you for your consideration.

Sincerely,
[Your Name]
[Class/Section]
