Despite many programs for educating social skills to adolescents with autism, insufficient attention has been paid to examine the optimal conditions and strategies that are important for improvement and generalization of the learned skills. So after reviewing and searching for three PubMed, Scopus, and ProQuest databases, 20 studies were finally analyzed and shared conditions were extracted. The results showed that the most important condition is parental involvement. The rehearsal and practice of social skills, attention to developmental trajectories, strengths and weaknesses of the individual and use of quantitative and qualitative tools are the other circumstances. In conclusion, taking into account these conditions for improvement, generalization and durability of the skills can be helpful.
