The PEAK Relational Training System's Direct Training Module was examined to determine age appropriate development norm ages in which to compare to persons with disabilities. Fifty-one typically developing children between ages of 2-18 were scored for the PEAK direct training assessment module by novel implementers (parents, caregivers) as well as professional educational teachers and administrators. Assessment implementation brought scores from fourteen different adult individuals and fifty-one different children's assessment forms for this study. The inter-rater reliability showed consistency of results with the relationship between Peak and age. Inter-rater agreement had a high degree of agreement through the same age, male or female, grade levels with student assessments on the PEAK rating pyramid. These subjective reports may be related and have one advantage that data results may be displayed conveniently in graphical form. The results suggest that there was no correlation between PEAK Total Scores and sex with R-Squared of .49, and produced a significant fit to the data (p < .001). Total PEAK by Age Group with an One Way Anova being: F(4,45) = 23.57, p < .001 suggest that the differences between ages in terms of PEAK total Score was significant.
