Posting this because I noticed the original link has changed. It helped a lot when I was doing my 504. It was created after a Massachusett's student died at school. It is a great doctrine and I hope someday it is implemented nationwide. Hope it helps.

I am also including another link to a very helpful website when putting together a 504. This is the site where I got the above link from as well.
