This letter is an example that demonstrates rational for the project and a reciprocal relationship. A letter from a superintendent is not required. This is just an example of a possible letter.
Dear Ms. X,
The School District is in full support of our partnership. Our organization has a long history of partnering in programs that benefit our students, parents, teachers and school communities.
We are reaching out to you in order for you to assist us with our on-going concerns with our STEM work. We have one school that we are concerned has not met the potential that we know our students can meet.
The recent economic downturn mixed with the teacher shortage has hit us particularly hard. In addition our students are not demonstrating that they are proficient in the areas of science on the CST (California Standards Test). The test score for this school show only 9% of our students are proficient in the area of science.
We would like an opportunity to discuss a possible partnership that could improve practice for your student teachers as well as our current in-service teachers.
Please contact me so we can discuss this further.
