Introduction: Through investigating all research proposals reached at the research deputy of Isfahan University of Medical Sciences, it was observed that researchers tend to attach very short and incomplete forms to their proposals despite the common tendency towards preparing appropriate informed consent form which is mainly due to lack of access to a sample form for modeling as well lack of instructional manual. This leads to return of proposals and a sheer waste of time. Hence, it was necessary to accommodate a suitable structure for preparing informed consent form for researchers.Method: in order to solve this problem, this research was carried out in a library-based mode and by using printed and electronic sources for searching the compartments of an informed consent form. In addition, in order to come up with a sample form, all websites of medical sciences universities were explored.Findings: All mention-worthy resources in an informed consent form were extracted by using all aforementioned sources and going over relevant texts, esp. the 26-part codes for protecting subjects in researches done in Islamic Republic of Iran. These parts were identified within two groups titled, “the cases needed to be mentioned in the form” and “the cases which are better to be mentioned in the form”. Furthermore, two sample informed consent forms were placed under the instructions which had been retrieved from the websites of other universities so that reverent researchers would opt them for preparing appropriate form and append them to their proposals with regard to the type of their research and the sample forms.Discussion and Conclusion: Attending to the ratified ethical codes and points in all researches done within medical sciences particularly those that involve human subjects are quite necessary. The best symbol for following such ethical guidelines is getting “informed consent” from subjects or their legal guardians. Among these codes, 9 refer directly or indirectly to the important issue of informed consent.bassically, any research done within medical sciences field has its own unique design and therefore, it requires a unique informed consent form which must be designed and used. By using the conducted classification in this research, researchers would be able to take care of preparing the informed consent form unique to each research on their own so that they could compile the best and most suitable research informed consent form by relying on their knowledge and prowess over their research content and topic.
