A purpose of this study is to know a perceptions of speech pathologist about classroom-based language
intervention(CBLI). We made a questionnaire based on literatures, carried out survey targeting 153 speech
pathologists and found out the general understanding of CBLI and the perception of a roles of
speech-language pathologist and intervention models. As a result of the study, First, it is low level that
the speech pathologist's general understanding of CBLI, and there are meaningful differences on the

recognized required roles on a stage preceding intervention's significantly, indicating meaningful differences
as work place and work experience. The Third is that there are meaningful differences as the awareness of
suitable model on CBLI. Through the research, speech pathologists didn't know well about the idea or
substance of CBLI generally. In case of CBLI, however, it is accepted to be an applicable form of
intervention at the language intervention of school age children. For speech pathologists, it is a pressing
challenge to develop a program of CBLI to fit in with domestic circumstance. Also, prior professional
education in training courses is important to recognize the role of speech pathologists on CBLI. With
regard to the model of CBLI, alternative teaching similar to domestic individual language treatment
currently is accepted to be the most suitable model owing to lack of understanding about classroom
situation. With thoroughly reviewing about intervention model based on those awareness, to arrange a
systematic guidebook that best suit our circumstance is conclusion of this study.
