Textbooks on research methods generally emphasize the need to collect data with high validity, reliability, and in the case of qualitative research, authenticity. Yet, field research often poses unanticipated challenges, particularly when the research is conducted in less-than-well-documented milieus. This article outlines field challenges encountered by the authors when doing a qualitative study of a slum community in the Philippines. Acceptable Western standards for gaining entry into a research community, for participating in local community life, and for the language and dress code used in the field had to be re-evaluated by the authors according to the prevailing Filipino cultural norms and the norms used in the local slum community. Lessons learned in this research can inform those doing qualitative research generally, but particularly those considering research in non-Western cultures.
