Dear [Principal's Name],

I am writing to formally resign from my position as [Grade/Subject] Teacher at [School Name], effective [Last Working Day Date].

Family circumstances require my full attention and caregiving responsibilities at this time. After careful consideration, I have determined that I need to focus on my family's needs, which requires stepping away from my teaching position.

I am grateful for the opportunity to have been part of the [School Name] community. Working with talented colleagues and inspiring students has been one of the most rewarding experiences of my career. The support and collaboration I received here have contributed significantly to my development as an educator.

I am dedicated to making this transition as smooth as possible for everyone involved. I will complete all outstanding responsibilities, prepare comprehensive materials for my successor, and document current student progress and classroom procedures. Please let me know any additional ways I can assist during this transition period.

Thank you for your understanding and support during this challenging time for my family. I wish you and the entire school continued success in all your educational endeavors.

Sincerely,

[Your Signature]
