Establishes "School Bus Safety and Child Protection Act," requires periodic criminal background checks for certain school employees; and prohibits interference with school bus monitoring devices.

This bill (S 543, "School Bus Safety and Child Protection Act") requires nonpublic schools and charter schools receiving state/federal funds to conduct criminal background checks every four years for school bus drivers, aides, and other staff with regular student contact. It also prohibits tampering with school bus monitoring devices, making it a crime to disable cameras or recording equipment. The law applies specifically to positions involving student interaction, such as bus drivers, security, and maintenance staff in eligible schools. Schools must verify candidates have no disqualifying criminal history per public school standards before hiring and annually notify the state if charges arise against employees.
