Reliability and validity of measurement tools in master dissertations is essential in flawless evaluation of research result. It ensures that collected data by these tools help in achieving results of study. Therefore, this study was conducted to investigate the properties of measuring tools used in nursing dissertations in Isfahan in 2015. this research is descriptive type of study. For this purpose, 237 dissertations of Medical Science University and 125 dissertations of Islamic Azad University were selected and analyzed using census sampling method.

To analyze the collected data, descriptive statistics using SPSS software was used.in this study, the most common measuring tool at the dissertations was questionnaire and 50.5% of them made by researcher. In the majority of dissertations, the validity and reliability of researcher-made and standard tool had been evaluated. Researchermade tools in most cases investigated using content validity and test-retest reliability. In 54.3% of the cases, validity had been examined by referring to reference, while reliability had been examined by Cronbach's reliability. Among the standard tools used in the dissertations examined, the validity and reliability for the tools for the available sample had not been re-examined in majority of dissertations. In studies where physiological measurement tools have been used, properties of these tools have not been considered in the majority of cases. the findings suggest there are some problems in the process of proving the validity and reliability of measuring tools used in dissertations, requiring that researchers, supervisors, and referees to pay enough attention for this issue.
