This study sought to evaluate the efficiency of the methods outlined in the Promoting the Emergence of Advanced Knowledge Relational Training System Equivalence Module (PEAK-E) utilizing a single-subject design. Three participants from a Midwest town were recruited to participate in the study and were assessed and validity, reliability, and efficacy were evaluated to determine the assessments ability to identify three language skills that weren’t currently present in their repertoire. Baseline levels determined that the 3 skills for each participant (a total of 9 skills across the 3 participants) were not currently present in their repertoire prior to implementation of PEAK-E programs, as the participants demonstrated low levels of correct responding. Upon completion of program implementation across all three participants with autism, mastery criteria was obtained for all directly trained skills, and relations were derived for 9 out of 9 programs.
