Authority and scope
Check the professional and concern
The Board accepts complaints about APRNs, RNs, LPNs, certified nursing assistants (CNAs), and medication technicians (MTs). An expired, inactive, or unrenewed license or certificate does not itself remove investigative authority.

Anonymous complaints are not accepted. The checked instructions do not establish that identity will be withheld from the subject; supplying contact details does not create a confidentiality guarantee.
