This is a follow-up study for the Exploratory Study on Attributes of Learners with At-Risk in School Setting for Early Screening(Choi et al., 2018) and includes school social workers who are conducting various education welfare programs for learners with at-risk in school setting as a research participant. The purpose of this study is to figure out school social workers’ concepts mapping and the importance rating about perception of the attributes of learners with at-risk by using concepts mapping analysis. For this purpose, based on 43 statements of the learners with at risk which were obtained from interview with 10 general teachers, 10 school social workers participated to sort those statements and to rate the importance of each statements. As a result, the attributes of learners with at-risk in school setting was confirmed to be suitable in two dimensions, and there were five clusters named ‘low interaction with parents’, ‘negative attitude toward teachers’, ‘low academic motivation and academic achievement’, ‘Negative psychological and behavioral problems in individuals’, and ‘interpersonal conflicts due to negative language and behavior’. School social workers perceived ‘Negative psychological and behavioral problems in individuals’, and ‘interpersonal conflicts due to negative language and behavior’ as the most important attributes. Based on these findings, this study suggested a discussion on the attributes and support of the learners with at-risk in school setting.
