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].

I understand this resignation comes during the academic year, and I sincerely apologize for any inconvenience this timing creates. Due to unforeseen personal circumstances that require my immediate attention, I must make this difficult decision to resign mid-year.

Despite the circumstances, I have greatly valued my time at [School Name]. The opportunity to work with such dedicated colleagues and bright students has been one of the highlights of my teaching career. I am grateful for the professional support and collaborative environment that made my work here meaningful.

To minimize disruption and support a smooth transition, I am committed to:
- Completing all urgent grading and student assessments
- Creating detailed transition documents for my replacement
- Preparing comprehensive notes on each student's progress and needs
- Organizing all classroom materials and curriculum resources
- Making myself available for questions via email or phone after my departure
- Working closely with administration to ensure continuity for students

I recognize the challenges this creates for the school and students, and I will do everything possible during my remaining time to ease this transition. Thank you for your understanding during this difficult personal situation.

Sincerely,

[Your Signature]
