Hi Ziggy, thanks for the question. It's a good one.
Remember this is my professional opinion, not a personal one, and it is not subject to my interpretation. It is based on law and validated by the courts. Hitting a child in the face is child abuse according to WV law.
For instance if the child went to school with bruises in the face, the teacher would have the same duty-to-report to CPS. If there is suspicion of child abuse, the teacher must either report or cause the report to be sent to CPS. If the teacher discusses the bruised face with her principal and he reports it to the Hotline, she is off the hook and the legal requirement has been met.
If a parent is known to be hitting their children like this a court will remove them from the home and put them into temporary foster care.
The parent then has 3 months (up to six months) to get counseling and convince the counselor and CPS worker (who represents the state and the child) that the parent has successfully passed parenting classes and under supervision can now provide a safe environment for the child.
If the parent is non-compliant then parental rights are terminated. That means the parent has no right to see the child, make any decisions about their care. The court issues a non-contact order which makes the parent a stranger to their biological child except with less rights.

In the case I said I intervened in, I strongly suspect she boogied so fast was because that was not her first contact with Children's Services, and she knew what the consequences might be.
You don't hit you child in front of a CPS worker.
