Social skills training (SST) refers to any adult-directed instruction in which social skills are targeted for improvement. SST typically occurs in either a group or individual format, and may also include facilitated practice in classroom settings. SST sometimes may co-occur with peer-mediated instruction and intervention (PMII) or some related use of peer models or tutors to support practice of targeted skills.
