Some schools have a Schoolwide Expectation Matrix, others have a School Policies document. Whatever your school uses, post it here. It is good to include a PDF version, as well as having the text on the page itself. DO NOT post an image (.png or .jpg) of your document, that makes it inaccessible to screen readers. For ADA compliance all the information must be in some form of readable text.
