“…This evidence supports the development of one unified assessment; the PEAK Comprehensive Assessment (PCA) represents a tool that may serve this function. Recent research has demonstrated initial convergent validity between the PEAK preassessments and the PCA ( r = .967; Moore et al, 2020). This suggests that the PCA may successfully unite PEAK preassessment items in one comprehensive assessment.…”

The Promoting the Emergence of Advanced Knowledge (PEAK) Relational Training System is a behavior analytic assessment and curriculum that has demonstrated evidence of convergent validity with standardized measures of intelligence. Correlational data (n = 66) between PEAK preassessment total score and standardized measures of intelligence showed a statistically significant correlation with an estimate of full-scale IQ (r 2 = .768, p , .001) and raw IQ (r 2 = .927, p , .001) as tested using the Wechsler Intelligence Scale for Children (5th ed.). Individual preassessment modules demonstrated strong and statistically significant correlations with an estimate of full-scale IQ (p , .001) and raw IQ (p , .001) with correspondence most tightly linked to the PEAK Transformation preassessment. Correlations between the four PEAK preassessments demonstrated statistically significant correlations (p , .001) indicating strong internal consistency. These results extend previous research establishing the internal consistency of the full PEAK system, the convergent validity of IQ and the PEAK preassessments, and relational abilities and intelligence more broadly.
