Agreed. The field is doing a lot to try and train therapists; however, as in all of child welfare, there is so much turnover. Also, evidence-based trauma training is expensive and typically involves a follow up of 9+ monthly supervision sessions. But it is where we must go!
Likewise, this is where I recommend that all foster youth be screened at intake for trauma experienced/level of...and that treatment clearly involve a response to PTSD appropriately and/or mental illness as may or may not be present.
