"The Professional Development Model (PDM), and specifically its Competence Certification (CCS) and Clinical Nursing Specialties Individualization (CNSIS) Systems, are part of these new professional regulatory responses, which are justified by the value they have in ensuring the continued achievement of the fundamental purpose of Ordem dos Enfermeiros, namely to promote the defense of the quality of nursing care rendered to the population, as well as the development, regulation and monitoring of nursing practice."
