    Abstract  Today science world changes sharply in a high speed. In a way that in all areas such as research methods these changes are obvious. Although concepts such as validity and reliability in Positivist methodology have been used with distinct and general rules, in post positivist period in which they have paid much more attention to qualitative research, these principles have lost their general form. In one hand some thinkers stress on applying common validity and reliability quantitative techniques in qualitative studies, on the other hand, some groups focus on distinction between qualitative and quantitative methods. Therefore, in this study we try to introduce the qualitative research methods and applying validity and reliability concepts in this way.  . Â
