The Social Skills Improvement System (SSiS; Gresham & Elliott, 2008) Rating Scales assist professionals in screening and classifying students ages 3–18 years suspected of having significant social skills deficits. The SSiS Classwide Intervention Program and SSiS Intervention Guide are manualized treatment programs for eliminating or reducing social skill deficits identified on the SSiS Rating Scales. The SSiS uses a multirater (parents, teachers, and students with at least third-grade reading ability) approach that provides a comprehensive examination of seven areas of prosocial skills (communication, cooperation, assertion, responsibility, empathy, engagement, and self-control) and five areas of problem behaviors (internalizing, externalizing, bullying, hyperactivity/inattention, and autism spectrum). The instrument yields norm-referenced scores based on a national sample representative of the 2006 US Census.
