Social skill deficits have become a defining characteristic of students with specific learning disability (SLD). Attempts have been made to enhance social functioning through structured training approaches. The effectiveness of these efforts was evaluated in a quantitative research synthesis (meta-analysis), which revealed a "small" effect with very few differences among teachers, peers, or students with SLD themselves who judged the efficacy of training. The relatively modest effects are discussed in relation to a number of theoretical psychometric and design issues that might account for the limited treatment outcomes.
