you are absolutely correct. The law speaks to social service workers but in the NYC DOE who used to relegate all reporting to a social worker or guidance counselor, they also have to report. It expands the responsibility of reporting and does not allow these mandated reporter to give the information to a social worker. If a principal hears the information, they also have to report.
Neighbors are not mandated reports though teachers are. The list of mandated reporters and the social service law can be located on the NYS website at the Office of Children and Family Service website. NYS is attempting to add clergy to the list, they are currently not included but other school staff are mandated reporters.
I also wish Morah the best, calling the SCR and prompting an investigation is a hard thing to do when you are not used to it.
