I'm not an expert -- but I sat on the site council at my children's school for 4 years...
First, there is still so much ignorance about ACEs that you may need to bring the Site Council up to speed on the existence of ACEs. Maybe bring a printed general article people can take home to digest. Maybe a second article on trauma's impacts in school aged children/ it's effects on learning.
I would begin by explaining ACEs, then talk about how unknown ACEs impact a child's ability to focus, learn, and concentrate... how it may underlie a lot of ADD, how kids with ACEs do not feel safe, how they may be victims OR bullies. These concerns-- learning and safety-- are central to any school's mission. A Site Council always wants to improve outcomes like these for students. So lay the table that way.
Then I would be prepared to offer some concrete suggestions that would be simple to incorporate to 1. raise consciousness about ACEs among the teachers & parents, as well as 2. ideas on what can happen in the classroom to better help kids who may be traumatized.
