The present investigation evaluated the effectiveness of the methods outlined in the Promoting the Emergence of Advanced Knowledge Relational Training System Equivalence Module (PEAK-E) using a single-case design. The validity and reliability of the assessments and procedures within the PEAK-E curriculum were examined across three children diagnosed with autism. The assessments contained in the PEAK-E Module were used to determine each participants’ current repertoire of existing derived relational abilities and language skills and to identify three appropriate skills to target during instruction. Results from this study demonstrated successful utility of the PEAK-E curriculum for teaching language skills to children with autism. The high level of reliability associated with the interobserver agreements in this study provide evidence of reliability of the assessments within the PEAK Relational System. Additionally, two of the three participants were able to acquire derived symmetrical relations and one student was able to acquire derived transitive relations.
