Forest School, a distinctive form of outdoor learning, was suggested to have a beneficial impact on the involved children. The purpose of this paper is to systematically locate and select existing articles published from January 2000 to December 2019 to identify what research had suggested in terms of the Forest School impact on the involved children. The present review of literature yielded seven positive Forest School effects on the children. In this paper, I solely focus on introducing the improved social and cooperative skills of the children as well as their physical skills and conclude with propositions for further studies.
