The purpose of the present study is to evaluate the efficacy of Promoting the Emergence of Advanced Knowledge Transformation Module System (PEAK-T) in teaching relational responding to children with Autism Spectrum Disorder (ASD). The current study was conducted on three participants that ranged from ages 5-10. The current study was conducted using a multiple baseline design across skills. A total of nine skills, three for each participant, were trained during this study. Baseline indicated that participants did not have skills previous to training. After skills were trained, participants were submitted to a post-assessment which results indicated the acquisition of novel skills that were not trained as part of the study. Results suggested the effectiveness of PEAK-T training on all three participants. The Average PND was 92% in the A-B relation training and a 100% when testing relations Y-Z. The post-Test results indicated that nine out of the nine skills were mastered after the skills were trained, in addition participants were able to acquire new skills that were not directly targeted throughout the study.
