Tools to assess the dispositions of counselor education applicants at the point of program admission are important as mechanisms to screen entrance into the profession. The authors developed the Professional Disposition Competence Assessment—Revised Admission (PDCA-RA) as a screening tool for dispositional assessment in admissions interviews. In this study, 70 participants engaged in a video-based training protocol designed to increase the interrater reliability of the PDCA-RA. An intraclass correlations coefficient was calculated as an index of interrater reliability. Cronbach’s alpha coefficients were calculated for internal consistency, and Fleiss’ kappa, free-marginal kappa, and percent of agreement were calculated for absolute agreement. Calculations were made for pretest and posttest scores. Results of the study suggest that the PDCA-RA demonstrates “good” reliability in terms of interrater reliability and “excellent” reliability in terms of internal consistency. The video-based training improved interrater reliability.
