That's fantastic that you're meeting with them, Brenda. Keep in mind it's a public school system -- its activities are supposed to be transparent, so a confidentiality agreement isn't necessary.
One thing you might ask about is if the school is intending to become trauma-informed. There are other school systems that are doing so, and they address the many types of childhood adversity in many different ways. I hope that you can impress upon them that focusing on CSA alone misses all the other complex trauma that's occurring, either along with the CSA or independent from it. A child with an ACE score of 4 is likely to have many more issues in school than a child with an ACE score of 1, no matter what the ACE is.
