Socially skilled students are more successful in school. Just like academic skills, social skills need to be explicitly taught. Students, including students who display at-risk behavior, benefit when social skills instruction is delivered schoolwide as part of a comprehensive intervention approach. This article presents a seven-step action planning sequence to facilitate schoolwide social skills instruction--highlighting how an expectations-within-settings matrix facilitates effective, efficient, and contextually relevant schoolwide social skills instruction. Useful tools, including an example matrix, lesson plan template, and implementation fidelity self-assessment, are included. (Contains 4 figures.)
