Jim Sporleder sent me this link, that might be useful to you, Brenda.
It's the Advocates for Children & Youth web site for Effective School Discipline for Maryland. They use Lincoln High School in Walla Walla, WA, where Jim is principal, as an example of best practice for a trauma-sensitive school.
Reforming school discipline can be a good pathway to a school looking at the bigger picture of how to help its traumatized students, no matter what the trauma is.
