[The competencies of health professionals and the ministerial policies].

In Brazil, nursing professionals are trained based on the perspective of professional competencies. The objective of this exploratory, descriptive study was to identify the critical-emancipator potential of the competency, as described by the Brazilian Ministries of Education and of Health. The sources used for data collection were the regulating documents of technical professional education of the referred Ministries regarding the years 1996 and 2006. Results showed that, for the Ministry of Education, the guiding principles of professional education are the demands of the working market; the idea of competency is supported on the constructivist perspective, highlighting personal features over their social dimension. For the Ministry of Health, professional education is an instrument of citizenship, guided by the political health care paradigm of the national public health system, referred to as the Unique Health System; the idea of competency is founded on the critical-emancipatory perspective. In conclusion, the two Ministries, despite having regulations regarding professional education, are contradictory in terms of their conceptual foundations.
