This review seeks to identify the processes, concepts and order of studies on the identification of sporting talent, to interpret them critically and generate a proposal for sports talent identification system (STIS) that is flexible and can be adapted to different contexts and ages. The population studied were children and young people. The concept was the talent identification systems, and the context is sports, in different places. The study was registered on the Open Science Framework (OSF). Searches were carried out in indexed databases and search engines with AI. For the study selection process, the protocol called Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA ScR) was applied, using the COVIDENCE systematic review tool. 58 papers were selected, mostly original studies and reviews, 47 of which considered the study of Biomedical and physiological aspects, 19 Psychological and 19 Environmental and sociocultural components. Geographically, most of the works were developed in Europe, North America and Asia. it is concluded that a STIS must be a continuous and cyclical process, considering physical and anthropometric characteristics, maturational state and psychosocial aspects, by means of easy-to-apply batteries, will allow the identification, creation of databases, monitoring and performance follow-up of sports talents in an efficient mode.
