The purpose of the current study is to validate the Counseling Competencies Scale Revised (CCS-R). We used convenience sampling to recruit counselors and counselors-in-training (N = 156). Specifically, we had 130 female (83.3%) and 26 male (16.7%) participants, and the mean age was 33.16 (SD = 11.18), ranging from 20 to 62 years old. We used correlational analyses, ANOVA, and confirmatory factor analysis to understand the characteristics of the sample and assess the psychometrics of the CCS-R-K. Results showed the validity and reliability of the data, including the acceptable model fits and high alpha reliability coefficient values. We also found that the scores of the CCS-R-K were positively related to participants' years of clinical experience and educational levels. The CCS-R-K can be used as a measurement tool to objectively and comprehensively evaluate Korean counselors' competency in counselor education, contributing to cultivating counselors with the professional competencies required by our society.
