The objective of this study is to investigate how Open Science (OS) values and practices have influenced open access (OA) journals publishers in Latin American and the Caribbean (LA&C) countries. Our key research question is: to what extent are these practices being adopted by LA&C journals? In order to address this question, we conducted a survey with a sample of LA&C journals listed on the Directory of Open Access Journals (DOAJ) database. The results reveal that many journals are somewhat aware of or informed about most of open science practices being discussed, but just some of them have already successfully adopted those practices.
