They grant CLPNPEI its authority to govern practical nurses, and its duty to do so in a way that serves and protects the public interest.

In accordance with the RHPA, CLPNPEI is authorized to maintain registers of practical nurses, establish entry to practice requirements, establish standards of education, develop standards and codes to guide the profession, issue practice directives, ensure continuing competence, and oversee the conduct of practical nurses.
