The purpose of this study was to evaluate the effects of two peers versus one peer on the rate of aided language modeling. The peers were trained and then implemented the communication strategy while playing a tabletop game with an AAC user with extensive support and complex communication needs (ESCCN). A multitreatment design was used to compare the effects of the rate of aided language models (ALM) provided by peers, the rate of communicative acts (CA) provided by the AAC user, and the fidelity of peer implementation of ALM when two peers versus one peer played a tabletop game with the AAC user. The results showed that the peer training was effective in teaching peers to implement ALM with fidelity across conditions. This study did not show differential effects in the rate of peer modeling and AAC communicative acts when one peer versus two peers played a game with an AAC user.
