This research aims at identifying and validating of indicators used to evaluate research productivity of Iranian researchers. In order to achieve this aim survey and documentary methods are used. Research society consists of a 80 person sample and members of this sample were selected among top researchers of country during recent years (1389-1390) from 4 subject areas of humanities, medical sciences, technology and engineering and basic sciences. Instrument for collecting data is a questionnaire including 47 items focusing on indicators used to evaluate research productivity of researchers. The Cronbach’s coefficient alpha was applied to confirm it’s variability and coefficient equal to 96% was obtained. In order to confirm its validity, formal validity method was used. Responding to questions and testing research hypotheses was conducted at two levels of descriptive and inferential statistics. At the descriptive statistics level, standard deviation, average and frequency and at the inferential statistic’s level, variance analysis, least significant difference and Friedman tests were used. Results of research show that for researchers of humanities, the indicators related to book have high importance while for researchers of basic and medical sciences, indicators related to article have more importance and from point of view of technology and engineering researchers, indicators related to innovations and research plans in comparison to other indicators are more credit at evaluating research productivity of researchers.
