Introduction and methodology The poster describes the results of the online survey on open science carried out on researchers affiliated with universities and Spanish research centres and focused on open access to scientific publications, the publication process, the management of research data and the review of open articles. The main objective was to identify the perception and habits of researchers with regard to practices closely linked to open science and the scientific value added is that offers an in-depth picture of researchers as one of the main actors to whom this transformation and implementation of open science will fall. It focuses on the different aspects of OS: open access, open data, publication process and open review in order to identify habits and perceptions. This is to make possible an implementation of the OS movement. The survey was carried out among researchers who had published in the years 2020-2021, according to data obtained from WoS. It was emailed to a total of 8,188 researchers and obtained a total of 666 responses, of which 554 were complete, the rest being forms with some questions unanswered. The overall conclusions are as follows: - The meaning of open science and its implementation are emerging topics that still require promotion, training and even persuasion to be carried out. - APCs present an economic barrier to those groups that do not have funding available for paying for them, although they are not the main criterion when selecting a journal. - Although Open Peer Review may seem innovative and emerging, many researchers have published or reviewed in journals that offer the opportunity for open review. - Tenure and evaluation policies do seem to have a clear effect on the behaviour of researchers with regard to open science. - Resolving the issue of evaluation in research may clearly condition the habitual uses of researchers when selecting a journal as well as the payment of APCs. - Researchers state that they share research data more for reasons of persuasion than out of an obligation to carry it out. - Researchers do not seem to question the objectives of open science, although they do question the pathways or difficulties that may arise from day to day. - Open access to publications and open research data are two realities that are increasingly consolidated in the scientific community. - Researchers seem aware that we are undergoing change, where academic evaluation or policies relating to open science, its implementation and shifting habits among researchers may change. In this sense, more and better support is needed on the part of institutions and teacher support services.
