The present study evaluated the relationship between scores on the Promoting the Emergence of Advanced Knowledge Pre-Assessments (Equivalence & Transformation Modules; PEAK) in one individual with autism spectrum disorder (ASD) and their corresponding performance on standardized IQ tests (WPPSI-IV Short Form), their performances on PEAK assessments following 10 weeks of treatment with four hours per week, and the corresponding obtained relational deceleration coefficient. The data indicated a strong, significant relationship between participation in PEAK treatment and an increase in scores on PEAK and IQ tests. The relational deceleration coefficient score did not change significantly. These results have the implications PEAK treatment is reliable and valid and should be used to help teach relational responding to children with developmental disabilities.
