It is a very rare child that can walk from traumatic abuse into a classroom and just “be normal”. The biology of trauma means physiological change happens. Before a human being can proceed to the next level of growth, like sitting for 8 hours a day in a classroom & passively soaking in lesson after lesson while interacting normally with other children, adults, and figures of authority, real healing needs to happen.
I have seen very competent extremely committed foster and adoptive parents come unglued when faced with the insanity shown by 5, 7, and 9 year olds who have been tortured. The World Health Organization defines torture as “extended exposure to violence and deprivation”.
All of the 50 children I worked with as a CASA volunteer had “extended exposure to violence and deprivation” (about half of them had been sexually abused, some as young as 2).
