I am preparing cover letters for several schools that I would like to work at. However, I am missing some information. The district job posting site does not say specifically what schools have openings in my field (special ed. para). I called a few schools and they don't really know if they have openings yet either. Question is, how do I write the first paragraph of a cover letter if I don't know if there are openings or not? Can I just act like there is an opening and hope for the best?
