The study focused on the strategies teachers used to manage inappropriate behaviors of learners with Asperger’s Syndrome. These are learners who exhibit inappropriate behaviors like self-injurious, aggression, repetitive behavior which includes obsessions and perseverations, stereotypes, lack of social or emotional reciprocity among others. These challenging behaviors are frequently the primary obstacles in supporting learners with Asperger’s Syndrome in schools. The purpose of the research was to identify types of behaviors exhibited by these learners, examine challenges teachers encountered when managing inappropriate behaviors, and assess classroom adaptations put in place to promote appropriate behaviors among learners with Asperger’s Syndrome in schools in Kisumu County, which was the study area. The study was based on the Theory of Mind which was drawn from Piaget’s Theory of Cognitive Development. This theory says, a child is supposed to develop some skills for social interaction, communication, and imagination before school going age but children with Asperger’s miss this, although they have developed language.
