The Laboratory of Evaluation and Qualitative Research in Health is an interdisciplinary group linked to the Postgraduate Program in Public Health of the Department of Community Health at the Federal University of Ceará. Formed by researchers from this University in partnership with different groups and collaborators from different national and international institutions, it also includes students, from undergraduate to Doctorate, in addition to postdoctoral researchers. The projects and studies developed are inserted in the different lines of research, based on the critical-qualitative approach, articulating with research networks of which LAPQS is a member and co-founder: Qualitative Health Research Network Brazil-Canada, a partnership built with Brazilian universities and the University of Toronto – CA (www.redequali.unb.br) and Iberian-American Research Network on Food and Society (www.redenaus.org.br). In addition to the courses offered regularly in the Postgraduate Program to which it is linked, LAPQS leads several training initiatives, such as thematic and methodological study groups; research training; project guidance; production of teaching material in the form of texts and videos; availability of collections with more restricted books; publications in journals and books on qualitative methodology and epistemology; organization of events and continuous participation in the most important congresses in the national and international scientific field, among other technical-scientific activities, developed within the thematic scope of the evaluation of programs and services and of qualitative research in health.
