Abstract
The present investigation sought to explore initial psychometric properties of the PEAK Relational Training System—Module 1: Direct Training for children with autism. Thirteen children diagnosed with autism or related disorders were exposed to an initial assessment designed to evaluate skill deficits within their repertoire, the Peabody Picture Vocabulary Test, and the Illinois Early Learning Standards Test. Additionally, staff performances were evaluated on reliability of delivery of the PEAK assessment. Results yielded significant positive correlations among the obtained PEAK assessment scores, the Peabody and the Standards assessments. Implications for evidence-based discrete trial training curricula are discussed.
