Hi Katie!
I commend you for considering the use of the ACES tool. I imagine Nadine Burke's center (Center for Youth Wellness) or Kaiser Permeante (in San Diego) could best answer your question as both of these places have used the ACES quiz as a screening/prognostic tool.
As one caveat, I think it's important for people to recognize that the tool can be triggering for many. In my personal opinion, the tool should be used in the context of high psychological safety - with a person that is trained to listen and has an established relationship with the patient.
We are a culture uncomfortable with people's hurt and suffering. As a result, we like to "rose color" glass (a Brene' Brown saying) a lot of very painful life experience. That can cause damage. It's like "rose coloring" a cancer diagnosis. We need to make room for people to feel what they feel, to say what they need to say in the moment, react how they need to react - and to be psychologically held. Otherwise, we can cause harm. Again, just to say it one more time, our own discomfort and what we do to avoid it can cause harm to others.
Again, I commend you for wanting to use the tool. I think it's a powerful conversation starter and awareness builder. You may just want to ask yourself, "Why?" and "Can we do this with great care and provide high quality response for the person?"
Best of luck...
