Sadly, we all need to know what being a mandated reporter means for us.  We also need to know the laws in our state and the policies of our companies. 

NAEYC Code of Ethics:

P-1.8—We shall be familiar with the risk factors for and

symptoms of child abuse and neglect, including

physical, sexual, verbal, and emotional abuse and

physical, emotional, educational, and medical neglect.

We shall know and follow state laws and community

procedures that protect children against abuse and

neglect.

P-1.9—When we have reasonable cause to suspect child

abuse or neglect, we shall report it to the appropriate

community agency and follow up to ensure that

appropriate action has been taken. When appropriate,

parents or guardians will be informed that the referral

will be or has been made.

P-1.10—When another person tells us of his or her

suspicion that a child is being abused or neglected, we

shall assist that person in taking appropriate action in

order to protect the child.

P-1.11—When we become aware of a practice or situation

that endangers the health, safety, or well-being of

children, we have an ethical responsibility to protect

children or inform parents and/or others who can.

     It is not enough to just tell a supervisor.  If you are the one who suspects or sees signs that there may possibly be abuse, then YOU have the responsibility to act on it.  Teachers and aides do not "get off the hook" by telling management.  We all have the duty to report, as mandated reporters.
     As hard as it is, we also need to let parents know that a report is being made (when appropriate).
