This study was designed to provide a systematic supervision of TA supervisee s professional development stages by considering the supervision model proposed by TA scholar Erskin. The first phase of the supervision focuses on the development of counseling skills and building confidence. This step provides information about counseling techniques for acquiring expertise, such as sophisticated observation and organization skills. It is also a step to encourage, support and assist in improving confidence while continuously giving positive feedback and constructive advice. The focus of the second phase of the intermediate-level Supervision is on establishing identity, improving the approach to counselling and therapy unresolved issues. This is the stage where supervisee develops a counselling intervention plan based on the theory of counseling. In particular, the journal enhances self-reflection and self-awareness, and promotes the ability to think about alternative interventions, thereby enhancing the confidence and competence of supervisee. The focus of the three-step advanced supervision focuses on professional skills development, counselling planning, and counselling evaluation within a single integrated framework based on various counseling theories. This is a step in which the supervisor can develop a framework for his or her theory of counseling and select various counseling plans based on the client observation and hypothesis of counselling. Finally, based on these analyses, future research directions and implications were suggested.
