The purpose of the present study was to examine the relationship between the PEAK Direct Training Pre-assessment (PEAK-DT-PA) and the PEAK Generalization Pre-assessment (PEAK-G-PA) with the corresponding indirect assessments based on parent and therapist reports. Participants were administered the PEAK-DT-PA and PEAK-G-PA. Parents and therapist completed a 184-item skills checklist for each of the corresponding modules. The results of the study suggest that there was a strong correlation between the pre-assessments and the indirect reports from both the parents and the therapists for each module. Additional correlations and inter-rater reliability across factors and individual test items were also investigated. Finally, trends in inter-rater reliability between caregiver report and direct assessments suggest that caregivers reporting for participants with lower overall scores more reliably identified whether their child had a deficit with an advanced skill, but could less reliably identify whether their child had a more basic skill. The opposite trend was found for caregivers reporting on participants with greater overall scores. Implications of these findings for clinicians and future research are discussed.
