The present study evaluates the criterion validity and efficacy of the PEAK-E Promoting the Emergence of Advanced Knowledge Relational Training System Equivalence Module (PEAK-E) through a single case design across 3 individuals with autism. Validity, reliability, and efficacy were all addressed in the study. The study showed that the PEAK-E assessment was an effective measure for skills which were not in the individuals’ repertoires. All participants demonstrated derived responses using the PEAK-E curriculum. After training all three participants using the PEAK-E curriculum, there was an overall increase in the participants’ abilities to derive relations when reassessed again using the PEAK-E assessment.
