Leave request from school
Subject: Leave Application
To: The Principal
KVM High School
I wish to inform you that I have to rush to Chennai on Wednesday 11th March to attend to my ailing father. Since my husband is out of town, I will be taking my daughter Shruti with me. She will therefore not be able to attend school from 11th March to 18th March. I assure you that this will not affect her studies in any way and I will make sure that she is able to submit missed homework and assignments on our return to Delhi.
Please grant Shruti leave from school for the concerned dates and expedite the same at the earliest.
* It is best to state in the opening sentence itself the reason for your leave
* Make sure that you clearly state the dates and not just the number of days that you wish to take leave
