IntroductionQuality assessment in the context of maternal health services in Brazil has been the object of study due to maternal mortality rates that remain high in the country, in addition to the high costs of healthcare and the increased level of complexity in care. To change this situation, several strategies have been proposed to improve care for women. One of them is the improvement of women’s access to maternal and child services through the Reception with Obstetric Risk Classification (ACCRO).ObjectiveTo map and synthesise scientific evidence in the literature of studies that assess the quality of ACCRO services from the perspective of users, professionals and managers, as well as map tools that assess the quality of these services and their results.Method and analysisIt is a scoping protocol that follows the method recommended by the Joanna Briggs Institute, other authors and guided by the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines. The Population, Concept and Context strategy will systematise the search in PubMed, Cochrane, Embase, LILACS, SCOPUS and Web of Science and PsycINFO databases. For the grey literature search: Google Scholar, Theses and Dissertations Bank of the Brazilian Institute of Information in Science and Technology, Federated Network of Institutional Repositories of Scientific Publications, Online Theses Electronic Service, Open Access Scientific Repository of Portugal, Academic Archive Online. Searches and application of selection criteria will be performed according to the PRISMA-ScR flow approach. The articles will be selected from the Web Rayyan platform, the results will be analysed and presented in a narrative and thematically organised way. This scoping review is expected to contribute to the feasibility of assessing the quality of ACCRO services.Ethics and disseminationEthics approval is not required. Results will be disseminated through professional networks, conference presentations and publication in a scientific journal. This protocol has been registered with OSF (https://osf.io/sp5df).
