In response, acomprehensiveprogramtopromoteprosocialskillswasevaluatedinaclassroomof16children between the ages of 3 and 5 years. Classroom observations were conducted during evocative situations to determine the likelihood of problem behavior (noncompliance, vocal or motor disruptions, aggression) and preschool life skills. A classwide teaching program was then implemented in a staggered manner across instruction following, functional communication, delay tolerance, and friendship skills. These four categories of preschool life skills, which includedtwotofourrelatedskills,wereselectedforclasswideteachingbecausetheywereeither identified by educators as important for early school success, have often been taught following functional assessments of more severe problem behavior, or both. Skills were taught on a classwide basis during typically scheduled activities (circle, free play, transitions, meals) via instructions, modeling, role play, and feedback. A multiple probe design showed that the programresultedinan74%reductioninproblembehaviorandamorethanfour-foldincrease in preschool life skills.
