S.K.
My only personal experience was when I had to report an abused student. TERRIBLE situation. Anyway, they picked him up from our school that day. Interviewed him and his mom, the abuser. Long story short, his mom had to promise to take parenting classes and he was sent right back home. So disappointing. I moved up a grade the following year and requested to have the same kid in my class so that I could keep an eye on him. His mom conveniently moved him to another district. I still think about him and wonder what happened to him.
I think it is ridiculous how differently cases are handled depending on the kids, the family, etc. etc. If you could have seen the scars on this kid's back, you would have NEVER dreamed he would have gone back to his mom. And then you hear the story of a mom spanking her child in public and they remove all the kids, go to court, blah blah blah. The system is broken. It lacks having enough people to cover the case loads, the ones who are there are totally overworked and it is so inconsistent with how different situations are handled.
