Your cover letter seems a bit long. it seems more like a statement of your philsophy on education. I didn't even want to read it all, I could imagine how a principal would...
suggestion I agree....I lost interest in the first sentence.... ~take the main ideas from each and bullet them ~these things will still stand out ~you will have the opportunity to make a bold point ~they will appreciate the fact that they don't have to read a lot
Thanks for the suggestions, I will try to make it a bit shorter. It is longer than a normal cover letter as the selection criteria need to be addressed in it.
