This paper presents a scale to evaluate the social interactions between students with severe disabilities and nondisabled students in integrated settings. The Educational Assessment of Social Interaction (EASI) was developed to be used with relatively little training but still be sensitive to the following major dimensions of interactions: (1) role (initiate/acknowledge); (2) purpose (social or task related); (3) topography (on task, no active participation, isolate, aggressive behavior); and (4) descriptive information (who/activity). A sample data collection sheet is provided and explained as is the scoring protocol, with examples given for each dimension. A sample completed data sheet is also provided and interpreted. (DB)
