Because it gets back to what is actually the barrier to education, I would never attempt to write a 504 on ACEs if a psych-ed hasn't been conducted first. I think it would be a dangerous direction for the community to take if we presume ACEs without ensuring that some other condition isn't at play. ADHD, anxiety disorder, learning disorder, etc needs to be identified first. Or demonstrated that they do not contribute to what is going on, also of assistance. Especially in girls, where diagnosing requires more expertise because things like ADHD are often mistakenly undiagnosed. It probably will also provide further evidence for the barrier to education, which can help fuel your need to write the 504, or maybe even evidence the need for an IEP. Good luck.
