Dear Principal,
I am writing to request permission to pick up my child early from school on [date] as we have a family wedding to attend.

Reason for Early Pick-Up:
- My child is an important part of the wedding ceremony and we need to leave early to ensure they have enough time to prepare and participate in the event.
- The wedding is a significant family occasion that my child is looking forward to and it would mean a lot to them to be able to attend.

Plan for Early Pick-Up:
- I will arrive at the school before the designated pick-up time to sign my child out of school.
- I will ensure that my child completes any missed schoolwork and catches up on any assignments that they may have missed.

Assurance of Academic Catch-Up:
- I understand the importance of regular attendance and academic progress, and I assure you that I will work with my child to ensure they stay on top of their schoolwork and do not fall behind.

Request for Approval:
I kindly request your approval for my child to be picked up early from school on [date] to attend the family wedding. I assure you that this is a one-time request and that I will make every effort to minimize any disruption to my child's education.
Thank you for your understanding and consideration.
Sincerely,
[Your Name]
