This study explored the experiences of master level trainee counselors leading unstructured counseling groups. Twenty-three graduate students were invited to co-lead eleven ten-session counseling groups over a two-year period. The major experiences of the trainees were collected using open questionnaire, and content analysis was conducted using open coding. Results showed that: (1) Group leading triggered self awareness, such as personal behavioral and emotional issues, interpersonal patterns, personal values and conviction, and family experience. In addition, in the process of leading the groups, personal issues were confronted; (2) Co-leading facilitated conflict awareness and adjustment, and consensus development and mutual learning; (3) Reflections about group counseling included self-affirmation for completing the learning process, recognition of group dynamics, and reconsideration of the leadership role in group counseling; and (4) Reflections about professional growth included developing self-confidence, changing professional attitudes and exploring self-approach. Discussions and recommendations for instruction, practice, training and supervision were proposed.
