I think that the training has to be better trauma-informed, and that means really understanding. There are a lot of generic tropes that are applied at the board. There is this idea that somehow trauma is going to sharpen your memory. This gets trotted out a lot in questioning. If it's so important, why wouldn't you remember it? To me, that speaks to a lack of understanding of how trauma actually works on the memory and the ability to verbalize. Having some training in that, and working with mental health professionals who work with individuals who have experienced trauma, would help.
We often put pieces of evidence in psychological reports. How effective they are and how much they're taken up by the board members gets a variable response. Learning how to read...what that might impact, or how that applies to an individual claim, would be helpful.
