A home care worker agency shall report the required home care worker registry information for each home care worker it employs on a paid, unpaid, temporary or permanent basis who is not exempt from the reporting requirement. Any exemptions from reporting shall be established in regulations promulgated by the department; provided, however, that the regulations shall include, but not be limited to, exemptions for victims of domestic violence, rape, sexual assault or stalking.
The department shall collect the following reported information concerning each home care worker:
Reported information for each employed home care worker shall be submitted and regularly updated by each home care worker agency subject to this section. The registry shall be updated at least quarterly. A home care worker agency shall collect and maintain the required information and submit updated information in a timely manner as determined by the department. A home care worker shall not be responsible for any costs related to the registry.
The department shall only make a home care worker's full name, identification number, name of any home care worker agency employing the home care worker and a list of home care trainings or certifications completed by the home care worker available to the public unless such information is exempt from disclosure by the department. Upon request from an employee organization, home care worker agency or aging services access point, the department shall provide all reported information to such entity.
The department shall promulgate rules and regulations and shall provide such forms and notifications as may be necessary to implement this section; provided, however, that the department shall minimize any duplicate reporting that may be required of a home care agency.
