Counselor supervision during this era pivoted from technique-centrism to interpersonal influence, foregrounding relational dynamics, rapport, and feedback as core development levers. Microcounseling and attending behavior were integrated into supervisor-led practice, enabling rapid, structured skill-building and immediate reflection within supervisory sessions. The period also anchored supervision in theoretical frameworks of counseling and psychotherapy, promoting theory-to-practice alignment and establishing a foundation for standardized practicum evaluation in training. Historical Significance: This shift institutionalized the view of supervision as a relational, influence-based process, shaping subsequent generations' emphasis on feedback quality, supervisee-counselor interaction, and evaluative strategies. It contributed to lasting changes in how supervisees are prepared, assessed, and guided toward professional growth, influencing curricula and supervision models for decades.
