The purpose of this study is to examine the effects of reflective counseling group supervision (RCGS) for military counselors. A convenience sampling method is adopted. Twenty-two military counselors participate in this study. Both qualitative and quantitative research methods are used for collecting and analyzing data. The results support our hypothesis that participants who received the RCGS would show a significant increase in their counseling competences. Four primary categories related to supervisory style, supervisory alliance, self-assessment, and supervising outcomes emerge as prominent and consistent from participants' learning experiences. RCGS can be an effective supervision model for participants. Implications of the findings for group supervision and further research are discussed.
