Dear [Principal],
[Introduce yourself].
I am interested in teaching at [School] for the 2024-2025 school year. I am currently a candidate with the Teacher Accelerator Program, a non-profit dedicated to mitigate the teacher shortage. With the program, I have engaged in a one-semester class through [respective university] and this summer I participated in a six-week internship. During the internship, I taught summer school alongside a veteran teacher and get daily professional development from an instructional coach.
