The purpose of this study is to suggest improved Special Instruction Classrooms(SIC) in terms of architectural planning based on the analysis of design characteristics and problems. For this study, SICs in 20 elementary schools located in Daegu were selected and investigated. The results of investigation showed that: first, the vertical separation type is mostly preferred for the layout of SICs; second, the top floor is preferred for the location of SICs. We suggest that first, each SIC should be located with consideration of the characteristics of subjects(<Tab 9>); second, the degree of adjacency-room preference for each room should be taken into consideration for the zoning of the SICs(<Tab 10>, <Fig 7>); finally, a direction for improvement for suitable architectural design of each SICs should be based on the feasibility of learning space(<Tab 12>).
