In terms of training and practice, the competencies required for community and family health nursing are established by law. They are acquired progressively and raise three educative issues: what should we teach each year; what we cannot teach because we do not know; and what we cannot teach because we do not do. The following article describes a line of research based on a mixed methodology that responds to two objectives: to facilitate residents' learning process and to provide a guide for tutors; while at the same time to learn about the self-perception of knowledge and training needs of primary healthcare nurses, consistent with their profiles and workplaces. Nursing practice styles can be classified as technical, controling and methodological. This proposal aims at crossing nurses' problem-solving process and problem-solving attitude, together with their need for information in order to document the nursing process. The number of nursing specialists is significant and will increase in the short term. These specialists are a human resource with a high level of competency guaranteed by law, and are readily available to deploy an arsenal of skills that will undoubtedly improve the quality of the public and private healthcare system. Unfortunately, they are currently not being harnessed as advanced service providers. The current law opens up the possibility for further progress in the accreditation of competencies, opening two paths that still remain unexplored. One relies within the specialty, in the area of training; and the other one can be found outside, among the accreditation diplomas and advanced accreditation. The competency-approach opens up opportunities for the entire healthcare system: patients, users and caretakers, together with nurses and other health professionals. The challenge is to put into practice the advantages offered by nursing specialties, consistent with the vision of advanced practice nursing in clinical management, meso-management and health policy. Perhaps the involvement of nurses in health policy will pave the way for the desired outcome.
