What approach would you consider if you find that a child is facing neglect or abuse at home?

I consider myself responsible for any student I teach. If a teacher is teaching students who are young enough to understand anything to do with abusing and neglect then teachers can do a quick health check to see if all their students are in good condition. The check could be either daily or weekly depending on the class strength. If there is a situation where I come across any student who is bruised or injured, I would bring it to the attention of my supervisors first. Then without offending the family members, we can discuss it with the family member who is close to the child. This way the child would feel safe and tell everything honestly.
