I would also be asking why you should keep your son there? We had similar issues in our version of K here with my oldest. I eventually pulled him and we ended up in 9 months of play therapy and 9 months of trying to help him heal from the trauma before he was ready to start considering learning again.
Homeschooling rocks and my kids can finally move at their own pace on any given day and learn anything that they feel interested in and motivated to learn about. I will never willingly return to the school system with my children.
