The purpose of this study was to examine the Peer Buddy Program at a high school for students with disabilities (i.e., learning and behavior disabilities) in academic and social achievement. Two specific questions were addressed: Do students with learning and/or emotional/behavioral disabilities, who are participating in the Peer Buddy Program, show improvement in their use of social skills according to self-report, special and general curriculum teacher ratings on a standardized social skill rating scale? and 2) Do students with learning and/or emotional/behavioral disabilities, who are participating in the Peer Buddy Program, show improvement in academic skill use according to past to present year comparisons on grade point averages, and special education informal assessments (Fast Math, System 44, and Acuity)? Student, special and general education teachers' ratings on the Social Skills Achievement Scale (SSIS) and student archival records data was examined through pair t-test analyses pre and post the Peer Buddy Program intervention. The results indicated that the Peer-Buddy Program had a positive impact on the social and academic achievement of high school students with learning and behavioral disabilities.
