The PEAK Relational Training Program has been recently published and favorable results for reliability and validity measures have been reported (Dixon, 2014). Results of two studies have demonstrated a high correlation with scores on the PEAK assessment scores, IQ scores as well as high reliability in scoring the PEAK assessments (Dixon, Carman, Tyler, Whiting, Enoch, & Daar, In press; Dixon, Whiting, Rowsey, & Belisle, In press). The current study evaluated normative data for Module 1 using 45 children ages 1 through 6 to validate it's utility in measuring the language of typically developing individuals. Normative data was collected and a strong positive correlation was identified between participants' age and PEAK assessment scores (r=.832, p=<.001). Implications support the use of PEAK to teach language and learning and continual investigation of its psychometric properties.
